Dual boot NAND and SDCARD

[hideoushog]

I am attempting to get my plug to dual boot. NAND boot is fine so it is just SDcard booting that is the issue. Everything works fine booting NAND with kernel 2.6.24.18 after which I can access the SDcard filesystem.

SDcard booting

I have consulted the PlugWiki FAQ and Howto and all the forum entries here. I have updated uboot to the  3.4.27 patch that I found in this forum. This has helped and the SDcard boot does now start. However, it still does not start when using the 2.6.32.8 kernel.

The only difference I can see is that the NAND boots from RAM after a direct copy from NAND into RAM whereas the SDcard boots from a file copied into RAM (uImage). Whether this is a cause of the problem I have no way to know.

I am now at a loss how to proceed. I don't want to do my development work using internal NAND, and wear it out. I note others seem to be wearing out their SD cards, which is a bit worrying.

However, since I do have one of the plugs with a SATA port maybe I should try that?

you also have a Bootargs_sd, which isn't being referenced, but is worth noting. bootargs_mmc is missing, but it usually contains the mmcinit and ext2load statements so that isn't necessarily your problem? then again, i don't think the mmc init is actually working below (i don't have any reference in front of me). maybe add a space between the ';' and 'mmcinit' in your bootcmd_sd.

you state that sd boot works fine with an older kernel, presumably 2.6.24.18?, but does not work with 2.6.32.8. the output you provided is confusing, though:

Linux version 2.6.22.18-6plug (sapere@dellgentoo) (gcc version 4.2.1) #1 Wed Mar 11 11:32:30 PDT 2009

i also see that bootargs_ip looks to be superfluous:

Kernel command line: console=ttyS0,115200 noinitrd root=/dev/mmcblk0p1 rw rootdelay=3 rootfstype=ext2 ip= 10.4.50.5:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none

what is the layout of your sd card?

[hideoushog]

Thankyou for the help so far, much appreciated. I am not sure what you ask for regarding my setup. It is a standard plug from NEWIT, uK with Sata port. I am using a 15MB/sec Sandisk SDHC ultra 8G card. I have not yet connected a sata drive as I don't have one but a USB drive does connect. I am close to getting the plug to boot from that, but I would like to be able to boot from SD card if possible.

I have removed the superfluous environment variables, (It was a bit of a mess, clearer now I hope)  made sure there is a space before mmcinit. So lets go through the log and see what it is doing. First I have done a printenv so we know where we are. I start with

Marvell >> printenv
Marvell >> boot  // This does a "run bootcmd_sd" if the SD card is inserted otherwise bootcmd_nand

We now see that "mmcinit" has worked and the SD card found. Space before mmcinit is not the problem. Next we see that the uImage file is found and the image is loaded into and starts to boot from ddram.

## Booting image at 00800000 ...

All seems fine and showing that Linux 2.6.22.18plug is booting.

Uncompressing Linux...

The point I make about version 2.6.32.8 is that it halts here. It also used to halt here before I installed the patched boot loader. Still that is not the problem I am trying to solve right now.

We get to the end of the log......

after the sdhci:... there should be some indication show it detect a SD card was in the card holder. in you case it show nothing so I suggest you use a newer version kernel if possible or change your SD card to non SDHC card. I think this version kernel have problem with SDHC card.

Good Luck

[mundhra]

as pingtoo stated, the sd card is recognized by uboot but it isn't being seen by the kernel.

i had assumed that you used the sheeva.with-linux.com kernel when you mentioned 2.6.32.8, but i guess i shouldn't assume.

for reference, your should see a section similar to the following for successful kernel sd card init:

Code:

my question regarding sd card layout is in reference to partitioning scheme; your settings indicate a single ext2 partition.

[hideoushog]

Thanks for the suggestions. I am starting to understand the log but this is all new to me.

What is interesting is that if I boot from NAND the SDHC card IS detected. It does indeed look like the SDHC card is not detected correctly when I copy uImage from the card into memory and then boot from memory. No idea why that should be. Here is what happens when I boot from NAND ...

I suppose I have 2 options

a) Go out and get an SD card
b) Try to get a bit further with the latest kernel

The trouble with b) is that I get no debug information. The boot process just appears to stop after uncompressing Linux .............................

If you have any other ideas please let me know. Thanks

[mundhra]

what are the origins of the kernel in NAND vs the kernel on your SD card?

personally, i would try the following:

- boot from NAND
- insert and mount SD to /mnt/sdcard
- download modules tar, uImage, and their md5s from here.
- follow the readme, performing the commands manually based on the fact that you aren't booting into the environment you're upgrading:

• verify modules tar against its md5sum
  verify uImage against its md5sum
• tar x -C /mnt/sdcard/ --overwrite -zf sheeva-2.6.32.8-Modules.tar.gz
• cp sheeva-2.6.32.8-uImage /mnt/sdcard/boot/

- then on reboot, interrupt uboot and set bootcmd_sd to 'setenv bootargs $(bootargs_sd) $(bootargs_ip); mmcinit ; ext2load mmc 0 0x800000 /boot/sheeva-2.6.32.8-uImage; bootm 0x800000'
- don't bother with a setenv, just boot and see if that works

(i've highlighted the main changes)

please note: i have not done this procedure manually, so proceed with caution.

i suppose another option would be to copy your NAND kernel and modules to the sdcard.

[pingtoo]

It is hard without actually access your environment to understand the discrepancy between your NAND setup and what is on SD, my guess is you have two different version of kernel.

As when no further output after kernel decompress usually mean one of the two thing, A. you did not pass console=... or B. the kernel was compiled without serial tty support.

What is interesting is that if I boot from NAND the SDHC card IS detected. It does indeed look like the SDHC card is not detected correctly when I copy uImage from the card into memory and then boot from memory. No idea why that should be. Here is what happens when I boot from NAND ...

I think there is one thing you may misunderstand. The 'NAND' is a form of storage in sheevaplug case. It is not memory in the since of you everyday PC. So when you boot from ether NAND or SD you always copy kernel in to memory and execute from memory.

Just remember one thing about why after the kernel decompress message nothing else come out. There are hardcoded stuff in u-boot to control how to load kernel. for any kernel version newer then the one come with sheevaplug you need to set two new [ttu-boot[/tt] environment variables

Code:

Marvell>> setenv mainlineLinux yes
Marvell>> setenv arcNumber 2097
Marvell>> saveenv

Good luck

[hideoushog]

Questions to answer.

My SDHC card is a single partition.
I do understand that uImage is stored in NAND, then copied to RAM before booting from RAM.
I also understand that uImage can be copied from SDcard into RAM and then booted from RAM.

Both these operations work as long as I make no reference to mmcblk0p1.
I have also managed to use tftpboot lo load the kernel into ram, with subsequent successful boot.

However, despite the fact that it appears impossible to boot the kernel with the SDcard as the root of the filesystem, once booted into Linux, the SD card files system can be mounted.

#mount /dev/mmcblk0p1 /mnt/sdcard

It is suggested that no output from the kernel bootstrap indicates either that the kernel is compiled without ttyS0 support or  that I have not started up ttyS0. Somebody in the know will have to tell me if the kernel is compiled without bootstrap support. For my part I am sure I have set up correctly. Please check my log though. I think I have included all salient information.

[pingtoo]

Did you cut and paste output from your terminal emulation program? If you does than it is rather strange, for example

Code:

2821728 bytes read
Marvell>> setenv bootargs=console=ttyS0,115200 root=/dev/mmcblk0p1 rw ip= 10.4.50.5: 10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none
Marvell>> printenv bootargs
bootargs=console=ttyS0,115200 root=/dev/mmcblk0p1 rw ip=10.4.50.5: 10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none

In your setenv bootargs=... you have ip= 10.4.50.5:... however the printenv bootargs show the ip=10.4.50.5: 10.4.50.5.10... the space between the equal sign and the IP address was shifted to second part. This does not make sense if you were cut and paste. It could only mean ether your terminal emulation program is doing strange thing or you u-boot have some strange bug. This problem also manifest in this portion of your output

Code:

CPU0: D cache: 16384 bytes, associativity 4, 32 byte lines, 128 sets
Built 1 zonelists.  Total pages: 130048
Kernel command line: console=ttyS0,11520 root=/dev/mmcblk0p1 rw ip= 10.4.50.5: 10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none
Unknown boot option `10.4.50.5:': ignoring
Unknown boot option `10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none': ignoring

Noticing the console=ttyS0,11520 the baudrate is wrong yet the plug can sent output to your terminal program.

It was never made clear that you did not compile your own kernel that is the reason I guess you kernel may have missing serial tty support. So if you got your kernel from somewhere that is build for sheevaplug than I would guess whoever build it must have tty support build in.

Lets try something simple to debug why the newer version kernel does not work. please do

Code:

Marvell>> setenv mainlineLinux yes
Marvell>> setenv arcNumber 2097
Marvell>> saveenv
Marvell>> reset
Marvell>> mmcinit
Marvell>> ext2load mmc 0 0x800000 /boot/sheeva-2.6.32.8-uImage
Marvell>> setenv bootargs 'console=ttyS0,115200 root=/dev/mmcblk0p1 debug'
Marvell>> bootm 0x800000

The debug should tell kernel to produce more verbose messages.

Hey, after I finish typing above I notice your did setenv bootargs=console=..., this is incorrect. When your try to set u-boot environment variable use setenv command you do not need the equal sign between your variable name and its argument. For example you should have it like this

Code:

Marvell>> setenv bootargs 'console=ttyS0,115200 root=/dev/mmcblk0p1 rw ip= 10.4.50.5: 10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none'

Good luck

  At last it works. Thankyou Pingtoo so much.

So I need to be very careful about spaces in the argument list and simplify my arguments as much as possible. Statements about woods and trees. This is the problem with doing things by rote from FAQ/HOWTO examples when you dont totally understand what you are doing.

[hideoushog]

Pingtoo ... I notice in your command sequence you set the mainlineLinux variable, save it and then do a reset.

Why is the reset operation necessary? What is tit that the boot loader is doing?

I can tell you that if you don't do the reset it does not work. Hangs after loading the kernel .....

This means dual booting is IMPOSSIBLE;

The reset is to ensure when u-boot startup it will be in right condition. this only one time process it should not be necessary for every reboot.

... What is tit that the boot loader is doing?

what is 'tit'?

[mundhra]

good catch, pingtoo. i looked over that with bleary eyes and had no idea.

hideoushog, the saveenv is writing the uboot environment variables to NAND. the reset is restarting uboot as would happen if you were to cycle power on the sheeva.

once you do the saveenv, you shouldn't have to do

Code:

Marvell>> setenv mainlineLinux yes
Marvell>> setenv arcNumber 2097

ever again.

likewise, if the following worked:

Code:

Marvell>> mmcinit
Marvell>> ext2load mmc 0 0x800000 /boot/sheeva-2.6.32.8-uImage
Marvell>> setenv bootargs 'console=ttyS0,115200 root=/dev/mmcblk0p1 debug'
Marvell>> bootm 0x800000

you should reboot, update bootcmd_sd and bootargs_sd appropriately based on what's above, saveenv, reset and be done.
