Enabling Esata on V1.3 Sheeva Plug - Progress Report.

[superpat]

Hi

Progress report,  early results!

Populating the Sata components and getting the Sata to work  on the "newer" V1.3 Sheevaplug appears to be feasible

I have got a SATA drive visible in uboot,  using a non standard uboot, (borrowed from openrd uboot 3.4.19).

I am using a 500Gb Samsung sata drive in an elcheapo  USB/Esata external case, Esata only connected.

I have not finished connecting all the filter caps on the power supply to the Marvell Sata section. They are so difficult, (one cap side pad is connected to the ground plane, which makes cleaning the pad flat very hard. the ground plane sucks the heat from the iron). However I connected the ferrite inductor  to power the Sata section, just to see if I could get any sign of life from the drive.

Here is the applicable uboot output:-

Now some warnings,  ( and I know I am 'shouting' )

1. DOING THIS WILL DESTROY ANY WARRANTY ON YOUR SHEEVA PLUG

2. IT IS VERY EASY AND QUICK TO DESTROY YOUR PLUG WHILST DOING THE MODS

3. FITTING THE COMPONENTS IS VERY HARD     You need SMT soldering equipment and  SMT soldering experience.

4.  EXTENSIVE SOFTWARE MODS are REQUIRED

/shout over

Caveats

I have not read / written data yet  I need to understand the format of the uboot ide read / write commands, and also where I can read and write to an area of nand that isn't going  tramp on the O/S, but the plug can get the drive info and the partition info, which is a good start.

I have NOT yet got the kernel to 'see' the Sata drive on boot.  I assume that it is done via udev. My problem is that I  am not familiar with udev in it's latest flavours.   If anyone can point me at a CURRENT tutorial on the current udev,  (I gather that using hotplug is now depreciated),  I will be very grateful.  Also any info you can provide on  the current convention for udev rules naming. When I Google for info on this I bog down in dozens of articles from when udev  was first introduced, but it has altered a lot in todays incarnation.

Now I have some progress, I will now finish installing the pi filter on the 3.3v power feed to the Marvell Sata section, and  work on  the software.

cheers

Edit:- just noticed cut and paste corrupted uboot o/p ide part in quote

it should have looked like:-

Just to say "well done! Great progress!".

I haven't made any new progress myself as I'm still waiting for the cheapo usb/esata dongle I ordered on ebay to salvage its esata connector.

Keep up the good work!

What ferrite did you use?
Something like this?

http://parts.digikey.de/1/1/350803-ferrite-chip-60-ohm-500ma-0603-blm18pg600sn1d.html
Is it 0603?

[superpat]

Hi Andy

I did post a pdf of the mouser part I used here:-

http://plugcomputer.org/plugforum/index.php?topic=683.msg5381#msg5381

It is similar to the DigiKey part, I think the mouser has more dc current capability though. Compare them yourself!

The ferrite is a 0603 part, the caps are 0402's!

I  am still trying to  cross compile a modified plug kernel, with sata initialisation  and  sata data stuctures. I am using a Marvell git clone, and modifying
plug setup.c.  However I am having problems creating a "non-standard"  mach-type sheevaplug.   I am trying to learn how the conditional compile is controlled. I wish I knew the process better. Then I would know which def files to edit.  For instance there is a mach-type file which defines the sheevaplug as 2097 and the Cetra plug variants as 2025 and 2026. I wish I knew where these identifiers were used.

Ah well  blunder onwards!

Hi

Some Sucess!

I succeeded in cross compiling a kernel with sata support for my plug.

The esata drive has to be "kicked" to make it visible to the kernel before booting. (power off/on)

I could not take a directory of the drive as I had previously formatted it in ext4, and my modified kernel does not support ext4

patrick@sheevaplug:~$ sudo mount /dev/sda1 /mnt
mount: unknown filesystem type 'ext4'

So I decided to fdisk it and format it with ext3

The fdisk went fine:-

patrick@sheevaplug:~$ sudo fdisk /dev/sda



The number of cylinders for this disk is set to 60801.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

This is getting a bit deep for me.  I have Googled the WRITE FPDMA QUEUED error and I found:-

Race-Free Status Return Mechanism

This feature eliminates the "handshake" traditionally required with the host to enable the status return, allowing the status of any command to be communicated at any time and the drive to complete multiple commands sequentially or at the same time

Interrupt Aggregation

The drive typically interrupts the host multiple times for each command it completes. The more interrupts, the bigger the host processing burden and the slower the performance. NCQ reduces the average number of interrupts per command to as few as one. If the drive completes multiple commands in a short time span--common with a highly queued workload--NCQ can aggregate the individual interrupts so that the host controller only has to process one interrupt.

First Party DMA (FPDMA)

NCQ uses First Party DMA to allow the drive set up Direct Memory Access (DMA) operation for a data transfer without host software intervention. The drive selects the DMA context by sending a DMA Setup FIS (Frame Information Structure) to the host controller. This FIS specifies the tag of the command for the DMA to be set up. Based on the tag value, the host controller will load the PRD table pointer for that command into the DMA engine and the transfer can proceed with no software intervention, allowing the drive to efficiently re-order commands since it can select the buffer to transfer on its own.

Please can anyone advise me... Does Marvell support this NCQ and FPDMA?,  Does my Samsung drive?  Is there a def in the driver I can switch it off when compiling?

How should I tackle this error?

Cheers

Patrick


EDIT 17:47

I threw away my cheapo ext Esata drive case and connected the Sata drive directly to the Plug with a sata/Esata cable I had in my junk box. I connected an external power supply to the drive and gave it another go to ext3 format the drive.

This time it completed successfully albeit with 7 of the same errors as I had previously. (I wonder if the power filters might help, I must may the effort and solder them in)

I mounted the drive OK and wrote and read a few short files OK.

I get a periodic (every tens of seconds), error in the sata system, it looks like the drive I have tries to go to sleep if not used, this appears to upset the plug's sata sub system, I want to run hdparm to tell the drive to keep spinning!

I have just screwed up my sd card ext2format, pulling it out of the powered plug, ( I needed to add the networking params so I could apt-get hdparm)

AGH!!

So I am back to fdisking my sdcard, then I will put the  rootfs back and the uImage I built and will try again

These Sd cards are most definitely NOT hot swappable!

Hi

A lot of progress today!

1.  The errors I was getting in the sata subsystem  were due to my new, (one month old), Samsung HM500JI sata drive being defective.

I replaced this drive with a Samsung HD501LJ drive I dug out, it appears to work perfectly (see later)

2.  I found that neither of two Esata / usb external enclosures worked with the Plug Esata  system

However connecting the disk drive(s) directly to the Plug  esata connector worked. I did not need to power cycle to get the drive(s) visible to uboot

My esata to sata cable is one metre long, and unshielded, but the  HD501LJ drive worked well.

3.  Summary of today's tests.

3.1  I connected the replacement Sumsung drive  HD501LJ to the Plug computer with an Esata / sata 1 metre cable and a 12/5 v power brick.
3.2  I started uboot and halted at prompt. Using the ide reset command I saw that Uboot had found the drive.
3.3  I then booted my modifed kernel uImage from  SD card.   The kernel loaded and loaded the ata  sata drivers and created a dev/sda.
3.4  I repartitioned the drive and formatted it ext3  with no problems.
3.5  I ran the bonnie++ disk test /exercise program, with no errors, still working out the timing info, putty really screwed the formatting! (Higher disk transfer is good lower cpu usuage is good)
Output from bonnie:-

Timing cached reads:   712 MB in  2.00 seconds = 356.04 MB/sec
Timing buffered disk reads:  244 MB in  3.02 seconds =  80.82 MB/sec


4. Work to be done.

4.1  Finish installing filter caps.
4.2  Find out why plug  sata system does not like my external enclosures on initiqalisation
4.3  Clean up modified kernel  and document.
4.4. Cut hole in sheevaplug case to access esata connector.
4.5  Get a RMA for the defective drive and return it, ( there is "lifetime" warranty on the drive).

Hi

More progress.

In my last reply, I wrote that I thought my 2.5in Samsung sata drive HM500Jl was defective, but before I raised an RMA, I thought I would test it.

I installed it in another linux box I have here and thrashed the drive, there were no errors!   --- Not the drive then!

I reconnected the suspect drive to the Sheevaplug, whilst doing so I noticed the "kettle" mains connecter to the +5/12V PS brick I am using was very sloppy fit.  I replaced this with a new kettle lead, much firmer push fit into the PS brick.

I was also unhappy about the heat generated from the 500G Samsung drive in a small sealed case, so I put it "naked" across an upturned plastic box lid, so air could reach the electronics on the underside of the drive, as well from the disk itself

I powered up the plug and rebooted my modified kernel.

I have repeated all the steps I did yesterday, which YESTERDAY showed the intermittent errors  and also did several more  tests .

I  have not recorded ANY drive errors today  ------ Hooray!   But I still don't know which "fix" fixed it!, I should have only changed one thing at a time!

I D/L'd  another tester prog:- iozone and ran that for an extended period of time.  I ran bonnie++ for a full pass    ---- No Errors drive or otherwise from either.

I used wget on the sheevaplug and D/L'd  debian-live-502-i386-gnome-desktop.iso to the drive, and then copied it to a new file name, repeated several times.

I checked the md5sum of the final copy against the reference on the DL site... they were still identical.

The 724838400 byte file took around 32 seconds to transfer, (file to file on the same disk)  which I work out as 22.6 Mbyte/sec transfer rate 

I have been thinking about repackaging the plug and hard drive into a aluminium die cast box. This would mean I can mount the drive in the box,  ensure effective cooling of the drive, keep all the cables inside, and generally make a neater server. 

My goal for all this has been to create a reliable home server that uses minimum power, that I can feel happy about leaving on 24/7. 

cheers

Hi,

I have spent a couple of days trying to understand USB / eSATA enclosures!

Connecting either my Samsung 2.5in or 3.5in  drives to my eSATA enabled Sheevaplug DIRECTLY, i.e.  bare drive plugged into a external 5/12v PS brick, and cabled straight into the eSATA port of the Sheevaaplug results in:-

1.  Uboot " seeing" the drive on a ide reset command
2.  Linux booting and running with my sata enabled kernel, will "see" the drive and create a /dev/sda and /devsda1
3. The system is quite happy to be hot plugged and unplugged, the /dev/sda being removed and replaced as the drive is unplugged and replugged
4. There are no data errors, and data transfers  are fine.

HOWEVER.  I have two eSATA  / USB hard drive external enclosures which struggle to work with the Sheevaplug eSATA (USB works on both)
One is a 3.5in EYE-T USB 2.0 and eSata Mobile disk, 3.5in model NS320ES
The second is a Pluscom 2.5in  model C221-INIC1608.

The problem with the 3.5in unit is that the SheevaPlug NEVER "sees" the drive subsytem either by Uboot or the kernel
The problem with the 2.5in unit is that the Sheevaplug ONLY  "sees" the drive after the power to the enclosure is removed / replaced.
Once the 2.5in unit is disconnected, and reconnected, the kernel cannot find the drive again and shuts down the sata driver.

Both  enclosures work OK  when connected to a i386 SATA  motherboard running Linux.  (I have not tried hot plugging the enclosures).

Looking at the guts of the enclosures reveals some interesting things.

Firstly the EYE-T enclosure uses an Initio inic-1610l  bridge i.c. 
It is quite a complicated i.c with an integrated 8051 microcontroller.  Here is the feature summary:-

1.1   Feature Summary
    •  Integrates USB2.0 PHY IP core.
    •  Data transfer rate of up to 60 MB/sec on USB side, 150 MB/sec on SATA side.
    •  Integrated internal Turbo 8051 uP with 16KB embedded SRAM.
    •  Program Flash In-Line (Firmware download mechanism, USB direct for MFG Test, write .bta file.
    •  Local Bus Interface to Serial Peripheral Interface (SPI) Flash Only.
    •  Support HID.
    •  Up to 9 GPIO pins.
    •  The option of using only one external crystal.
    •  Provide software utilities for downloading the upgraded firmware code under USB.
    •  Supports SATA (bridged SATA) Hard Disk drives, CD-RW devices, DVDs, Removable media devices
    •  USB 1.1 and USB 2.0 compliant.
    •  USB Mass Storage Class Bulk-Only Transport Specification Compliant.
    •  SATA specification 1.0 (1.5 Gbps), SATA II and eSATA Compliant (Hot Plug is supported).
    •  Support SATA to SATA pass through.
    •  Supports SATA NCQ.
    •  Supports 3Gbps SATA host and 3Gbps SATA HDD connection to internal 1.5Gbps SATA Phy.
    •  Support ATA/ATAPI device DMA and PIO mode.
    •  4k bytes of data buffer for data transfer.
    •  One SATA channel support.
    •  On-Chip 3.3V to 1.8V regulator.
    •   64 pin LQFP

The block diagram shows that the serial data signals from the host pass through the I.c. where they are muxed with the sata signals derived from the USB connection. The two serial data lines then leave the chip to connect to the disk drive.

Note the maximum data rates for the USB and Sata  connections!

The 2.5in Pluscom enclosure also has an Initio I.C. but in this case it is a inic-1608l.  This ic does NOT have a sata port, it is ONLY a USB to sata converter, as far as I can see, the two serial lines from the input eSATA connector go directly to the sata drive connector, but the output of the inic-1608l ic, USB to Sata is wired in parallel to the drive connector.  Again the ic has a 8051 microcontroller.  The USB data rate is specified at 60MBps. Obviously there is no sata data rate.   If the 8051 is not running correctly, perhaps it shuts the o/p of the chip off, stopping the sata connection running as well

I had a hard look at the external enclosures available.  There does not appear to be many true SATAll specification  enclosures.  most devices on the market appear to be Chinese clones in the Pluscom vein.   (The Initio bridge Ic vendor does not appear to support more than 150MBps on any of the 4 chips they sell.

Now the inition inc-1610l does state that hotplugging is supported in the chip, but I have no idea whether the EYE-T manufacturer has implemented it in the firmware of the 8051!

Have you ever seen a ext enclosure manufacturer offering a firmware update ?

I have found a reasonable priced vendor of the Antec MX-25  enclosure, and ordered one, just to see if paying for a more expensive product will result in one that works. It should arrive in a few days.

I am thinking more seriously about installing the Plug and drive in a metal box.  My misgiving is that the price of it this  development will soon reach the price of an OpenRD box!  However this is much more fun.  It keeps my brain from completely melting into mush! I am retired and I cannot abide watching the cr*p on the  tv every night!

cheers for now

Hi,

Whilst waiting for my more expensive 2.5in esata / usb enclosure to arrive, I thought I would play around with my Samsung HD501LJ 500 mbyte sata drive. I think it is faster than the 2.5in drive I also use.

To make it more interesting I thought I would try to boot off the Sata drive, instead of running the kernel from a SD as I usually do.

 I put the drive on my 386 Linux box,  created a "rootstock" ubuntu  root file system on the drive,  put my modified kernel uImage in  the /boot directory, edited the /etc/network/interfaces file.

I then attached the drive directly to the Sheevaplug, using a 5V/12V power brick, powered the Plug, typed in the boot commands  and booted the drive!     

For proof and FYI here is the console message... Note the Sheevaplug finds and uses ata2 for a Sata2 device!

Hi,

Well this is about the last progress report, I have come to the end of the saga, and I am a happy bunny.

My new Antec "Veris" MX-25 2.5" ext USB / E-Sata enclosure arrived today.  I installed my Samsung 500Gb Sata drive, but did not connect it to the plug.

I booted up my sata enabled kernel on a SD card,  when  system was settled I connected the Enclosure to the Plug firstly by USB

I ran the tests I did on the previous reply (on my 3.5 in drive) and got the following results:-

USB CONNECTION
hdparm
/dev/sda1:

 Timing buffered disk reads:   76 MB in  3.06 seconds =  24.85 MB/sec 
 Timing cached reads:   590 MB in  2.00 seconds = 294.36 MB/sec

1024000000 bytes (1.0 GB) copied, 32.9567 s, 31.1 MB/s

I then umounted the drive and disconnected the usb cable. I powered the enclosure from a +5v brick and connected the eSata cable to the Plug.

The running system "found" the new sata drive and created the /devs for me !  Removing and replacing the drive several times, "hot plugging",  works fine

I then ran the same tests again:-

E-Sata connection
hdparm
/dev/sda1:

 Timing buffered disk reads:  192 MB in  3.02 seconds =  63.57 MB/sec
 Timing cached reads:   630 MB in  2.01 seconds = 314.12 MB/sec

1024000000 bytes (1.0 GB) copied, 11.9506 s, 85.7 MB/s

The only "funny"  remaining to be investigated is once when I plugged the Esata cable into the enclosure, the Putty connection closed itself. When I restarted it and reconnected to the Plug, I was still logged in and  the Plug had not taken a dump, there was no dmesg or errors in any log files. All I can think of is that there may be a bug in  uboot.

Since the E-Sata connection  appears to being performing very well now, I am going to cut a hole in the plastic case of the plug to accomodate the E-Sata connector, (ala the Ctera Plug). and box it all up.  I haven't yet added the four filter caps to the Plug sata power supply, but I have to do that, although there does not appear to be any problems with them not fitted!

I will then install the required apps to build my home server!

 I will try to create an illustrated account of the modifications, hardware and software on the PlugWiki, ( I have opened an account, but I have to learn how to create a "how to" article).

One thing I am not clear about, is how to document and name the modified kernel, so as to avoid any chance of people confusing it with "normal" kernels.   The mods are very minor, only a couple or three lines in   arch/arm/mach-kirkwood/sheevaplug-setup.c  There is of course the need for the modified uboot which I obtained from the openrd  archive.

If anyone wants any info please reply here or drop me a PM

cheers for now

Patrick

Edit for punctuation

Edit  I cut a hole in the SheevaPlug case and stuffed it all back inside.

Added picture of modified Plug with E-Sata drive connected!

Does that mean I have put on the wrong components?

@Guai888

Hi,   Nice to read that someone else is having a go at Esata!

Firstly.... You write "put on the esata connector and the components".

Have you installed ALL the components. If not, the critical ones are the 4 series decoupling caps to the esata connector, and the Ferrite inductor (BIT7) that conducts 3.3V power to the sata section of the Marvell SOC.  (Its good to install the pi filter components if you can).

I have already documented the component values and locations  at length in the  hardware forum, mainly in the http://plugcomputer.org/plugforum/index.php?topic=683.msg5371#msg5371, but also in this post, earlier replies.

I installed Uboot  I borrowed from the Openrd forum, I  haven't tried esata with the SheevaPlug uboot, didn't know it supported sata ! My u-boot announces itself thus:-

Hi Superpat,

I have change the uboot to Open-RD. Here is what I got:

I think I have put on all the component correctly but it is time for me to recheck.

Hi,

You are 50%  complete now.

The Marvell SOC sata section is alive and well!

It looks like the communication between the drive and the Soc is not OK

There appears to be a problem either

1. Between the Marvell Soc and the esata connector  ( i.e.  the 4 serial decouple caps, or the esata connector soldering)

2. Esata cable and sockets.  I found the Esata / esata cables I had purchased had very thick plastic grips on the connectors which would not allow the pins of the connector to enter the sockets fully,  I had to trim back the plastic surrounding the esata sockets on both my drive enclosures' end plates, to allow the esata plug to make contact properly.

3 The sata device you are connecting to the esata connector    What have you got connected?    I found that one of my cheap external enclosures would NOT work with the Esata connection at all, the other only connected after removing / replacing the 5v power connector several times, or unplugging / replugging the esata cable.

I found the PREFERRED way of testing the sata channels was to connect a sata drive, bare, directly from the sata connection on the drive to the esata connector on the sheevaplug, using a Sata to ESata cable I had in my spares box, ( it was a 1 metre cable but worked fine).  I powered the drive from a small 5V 12V power brick and a sata drive power connector.
This eliminates the possibility of your esta enclosure not being "compatible" with the Sheevaplug

I am convinced a lot of the  cheap enclosures  although fitted with USB and Esata ports do not function with Esata properly. I think there may be issues between Sata 1 and Sata 2  standards and speeds.  I went as far as purchasing a Antec enclosure, nearly £30 retail, this connects to the Plug first time every time, with no need to pulse the power or esata
cables

YMMV

good luck

Hi Patrick,

I double checked my board.

C197 on the CPU side
C196, C78, C79 on the (K column) right above BIT7
BIT 7

C164, C188, C190, C189

Do I miss any components?

I am pretty sure that Open-RD uboot is working. I just can not get it pass the initialization.
If I pull out the eSATA cable, the prompt will immediately inform me that drive fail to initialize otherwise it will just wait for a long time before prompt return and inform me that drive fail to initialize.
I assume that uboot was waiting for some thing from the drive but never get it so it just time out.
Do you need to set any environment variable?

Best Regards
Paul Liu
