apemberton, my Fedora 3.10.10 kernel IS a device tree kernel, booting a dreamplug device tree.

I have noticed that the device trees from Fedora are not the same as the device trees from Cbxbiker, so I will have a look at that and see if I can fathom if there is anything there.

PQA, is your Fedora 3.10.10 kernel a Device Tree kernel? If not, this should help confirm that the console issue is in the Device Tree rather than the kernel itself.

I had a little look at schematics for a Guruplug and some of the Kirkwood data sheet and some of the MPP pins have multiple functions set up depending on initialisation. I see that MPP8 is shared between a gpio control of RTS (Request To Send) for serial and SDA for i2c/smbus; MPP9 is shared between gpio CTS (Clear To Send) and SCK for i2C/smbus.

I have the feeling that when the hardware is activated by the Device Tree code, the setup is not performed correctly for UART0 and possibly for other hardware. I'm not particularly familiar with the Kirkwood architecture so poring over code and datasheets to tie up the devices and initialisation may take some time and I do have other things to do. I am convinced that the kernel itself (as opposed to Device tree) is OK and the problem is not a .config issue.

I have just booted my Dreamplug on a 3.10.9 cbxbiker kernel, and also a 3.11.1 kernel, and like others I am not getting console output.

I have also attempted to boot a Fedora 3.10.10 kernel, and that IS prodicing console output. It won't bring the system up, however, since for some reason it is not loading orion-ehci.

So it would appear that it is probably not a kernel problem that is causing the lack of console output, but a build/configuration issue.

I know this product is old and hardly state of the art these days but I rely on them for my network services. Lately, they have become less than perfect in the reliability stakes. I cannot let this situation continue.

I find that I get errors on both MMC (sdhc cards) and hard disks. I am in the process of rebuilding them with external power supply and heatsinks to keep things cooler inside but I am still getting write errors on the unit rebuilt. I have replaced the RTC battery and the micro SDHC card.

In order to improve reliability, I am wondering if the second Sata port has all the components and the second micro SDHC 'socket' is equippped as well. I have checked the board traces against the schematic so I guess this was in the mind of the designer. I know I will have to get connectors as a minimum but I am wondering if anyone has already equipped these second ports and what was needed to make them work (hardware components, u-boot and kernel tweaks)?

Since I need at least two gigabit ethernet ports for routing etc, there are not too many replacement options - perhaps the Smile plug but that is a bit pricey for the job. Any suggestions?

Marcus,

Thanks for your survey. Actually I am using 32Gb Sandisk Mobile ultra for my Guruplugs! I use 16Gb Integral Endurance (which had been recommended by NewIT because of their Single Layer Cell structure) for the two standard sheevaplugs. However, my other three Sheevaplugs are eSata and boot from the HDD drives (3Gb/Sec interfaces) and I am struggling to rebuild my development system with new 320Gb Western Digital Scorpio Blue drives. Although it cannot be related directly to the Guruplugs, I have tried things like 50cm cables, common power supplies (to avoid ground loops), replaced corroded RTC batteries but still there are issues. I have not seen problems with my eSata Tonidoplugs (also kirkwood) which boot from internal 1TB eSata disks.

I will say that the i-node errors seem to occur at approximately the same location which suggests overuse of the same cells of disk sector.

I did also find these errors on an old 3.7.7 non-Device Tree kernels.  Undecided

I am considering setting up a cron job to reboot my systems automatically during sleeping hours to effect a fsck daily.

Hi Tony,

I've researched the 'slowdowns' and found that in my case the SD card had been optimized by the manufacturer for cameras etc with large block sizes for read/writes. This will make a login to linux take up to 10s - 10-20 IOPS! Absolutely pathetic. 

If you can get the Sandisk Mobile Micro Ultra 16-64gb cards they are made for small read/writes in phones and I've benched them doing 4kb read/writes at 300 IOPS / 16gb card and 400IOPS / 64gb card.

They also support trim (sadly only exists as an IOCTL in the raspberry pi kernel, not the sheeva) and supposedly have some wear leveling according to the data sheets.

Suffice to say I won't use anything else any more.

The numbers speak for themselves:

Marcus, I had my suspicions that Device Tree for Kirkwood and Dove kernels were the problem and your work confirms that. Thankyou. I would have tried compiling a non-dt kernel but time has not permitted experimentation. I now no longer need to. I am puzzled why there are no more reports of this problem from others though? I do not want to delve into kernel issues as I want to consider the kernel as a 'black box'. Increasingly it seems that I have to. The same is true of u-boot. I want the latest versions to have significant improvements or corrections to the system - much like Microsoft Windows has updates that should be bulletproof (well that is a commercial product - OK I've got the carbolic soap ready to wash my mouth out). I am wondering if Netconsole is compiled into the kernel which might give a workable console when the serial port does not.

I also have had problems with hard disk or SDHC writes which may be kernel synchronisation with the HDD or the SDHC hardware and I have the feeling that there is something wrong with low level file system software (it seems that the problem happens to ext3 and ext4 formatted partitions) and I have seen slow writes being a problem. Every so often the number of errors seem to make a disk go read-only and requires a reboot to force a fs check. That corrects i-node errors. I note that the errors are frequently in the same 'place' so that suggests that a regular type of write for a certain section of code. That said, I think that the temperature inside sheeva and guruplugs may be a factor and a nice version of sensors for sheevaplug would be nice.

Thanks also for the u-boot BTW. I had noticed compilation issues with my version in that mmc has been 'mucked about with' and I want ext4 built in.

OK, so I'm settling on the fact that devicetree is evil and additionally no one cares about fixing it.  Who am I to go against the flow? Smiley

I upgraded from debian wheezy (originally installed via network installer to sd card) to debian jessie, which at the time of writing had a non-device-tree kernel 3.10.2 with the revolutionary benefit of console output.

Here's my environment excluding ethaddr:

z_bootinit=mmc rescan; usb reset; ide reset;
z_bootstrap=run z_bootinit; run x_bootstrap_scr; run x_bootstrap_cmd; run x_bootcmd_mtd; run z_bootfail;

If my notes are to be believed, this should be the set of commands to change the stock nvram to the above:
Code:
setenv initrdaddr 0x01100000
setenv initrdfile /uInitrd
setenv kerneladdr 0x00800000
setenv kernelfile /uImage
setenv x_bootargs 'console=ttyS0,115200n8 earlyprintk mtdparts=orion_nand:768k(uboot),256k(uboot_env),11m@1m(kernel),-@12m(rootfs)'
setenv x_bootargs_root 'root=/dev/mmcblk0p2 rootdelay=5'
setenv x_bootstrap_cmd 'for device in "mmc"; do for fs in "ext2"; do setenv loadcmd "${fs}load ${device} 0:1"; if ${loadcmd} ${kerneladdr} ${kernelfile}; then; if ${loadcmd} ${initrdaddr} ${initrdfile}; then; run z_bootcmd; fi; fi; done; done;''
setenv z_bootcmd 'if imi ${kerneladdr}; then; bootm ${kerneladdr} ${initrdaddr}; else; echo --- next bootcmd device try ---; fi;''
saveenv

Its 99% that its due to the Power supply unit.
Simply buy a regulated PSU from ebay for a few quid (5v and 2amps) and, with a multimeter and some soldering, you will be able to fix it easily. You can simply take out the old psu and wire up the new. Newit also sell a sheeva PSU module but you have to ask -  will it fail again?
checkout my name and posts on newit's forum and you will get pics of how to do it.
