Sheevaplug: Verifying Checksum ... Bad Data CRC

[MattB]

Hi Everyone,

Just to warn everyone, having only been introduced to Linux within the last 2 years, and coming to the plug from the NSLU2, which (at least at the moment) seems a bit simpler, I am very much a beginner with this type of thing, so please be patient!

I bought a Sheevaplug from New IT off eBay the other day, and it arrived yesterday. My NSLU2 has been overloaded beyond belief and it is just too slow, so I was looking for something with a bit more grunt to act as a home server running things like CUPS, Transmission, Samba, Apache and maybe a webcam.

I was worried about the relatively small amount of space on the plug when it arrived. I decided to move the root file system to an SD card I had (Sandisk 4Gb card) so I followed the guide on the wiki here.

When I got to the part to do with UBoot, as per the guide, I changed the bootargs using the command (I did check that my bootargs were initially set the same as those in the guide, and they were, so I thought it would be fine):

Code:

setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p1 rw ip=10.4.50.4:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none

And then checked it using printenv bootargs. All looked well, so I typed 'boot' and the plug booted. I watched it boot, and a couple of [failed] notices came up, but Debian (mine has Debian on it as standard? I am not sure) booted, I logged ina dn all was fine. I also SSHd in to prove to myself that it wasn't broken. All worked well.

I then repeated the process (shut down, got into UBoot, setenv bootargs etc) and included saveenv at the end, as I figured the changes I made were good.

That seemed to go well. Then I typed 'boot'. I got this:

Code:

Marvell>> boot
NAND read: device 0 offset 0x100000, size 0x400000
Reading data from 0x4ff800 -- 100% complete.

   Entry Point:  00008000
   Verifying Checksum ... Bad Data CRC

This seems to happen without fail every time I turn it on. I tried setting the bootargs back to what I had originally, with this line:

Code:

setenv bootargs console=ttyS0,115200 mtdparts=nand_mtd:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw root=/dev/mtdblock1 rw ip=10.4.50.4:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none

But it still does the same thing upon boot.

So I have a couple of questions - first of all - did I go wrong anywhere obvious? I would love to fully understand what caused this, as well as how to fix it.

Second - how can I fix it? I have found a couple of other threads which sound similar, and they suggested restoring via USB - so this would mean following these instructions?

I would be grateful for any help anyone can offer - as I say, I am a bit of a newbie, but eager to learn from my mistakes!

Thanks,

Matt

OK! So thanks to the instructions on the wiki and in the README, I have managed to reflash the plug with Sheevaplug Installer 1.0. I had quite a lot of hurdles to jump while I was trying to get it to work, but I think a lot of it stemmed from my inexperience with almost all aspects of the process.

In case it helps anyone else, I bought my Sheevaplug from New IT in the UK, and I did not need to change the vid and pid in the conf file (in fact, as it mentioned 'newer plugs', I changed them and it didn't work, so i had to change them back) to run the installer. I tried it on my girlfriends Vista laptop, but it was much easier to do everything on my Ubuntu box. I (stupidly) kept trying to connect to ttyUSB0 to see the console, then realised the port I wanted was ttyUSB1. Once I realised all the mistakes I was making, it went great!

But all good news - it works again. I will no doubt try and move the rootfs to the sd card again sometime, but for the moment I'll stick with 512Mb and see what I can do.

But all good news - it works again. I will no doubt try and move the rootfs to the sd card again sometime, but for the moment I'll stick with 512Mb and see what I can do.

When you do switch to moving the rootfs to SD you'll need to have an mmcinit command in you boot command (it's absent from what you posted above).
I've set mine to boot from SD too.  The SD card has /boot (first partition, small). / (second partition - 4GB), swap (500MB) and /local (~11GB - where all of my stuff goes).  The advantage of this is that kernel updates (which get posted here) just involve:

• unpack the modules to get /lib/modules/2.6.xx.x
• copy the sheeva-2.6.xx.x-uImage to /boot and hard-link it to uImage (what my boot command expects)
• reboot

No flashing required.

Hi birdman,

Thank you for the advice. Actually, just after I posted that reply, I read this.

So I changed my bootargs_root to match that, and now it boots from the SD card no worries. Good times! Funny how some nights I can get anything to work for the life of me, and then other nights I'm on a roll.

Thanks,

Matt

Hi MattB,

I read your last post very carefully, read also the topic: 'Boot from SDcard with Alpha 6' and the HowTo: 'SD Card As Root File System', but my trys always fails....

My SheevaPlug has now UBOOT version 3.4.24 but every SD Card I used for debian installation via tar ball or debian installer stopps in reading uImage from SD Card.

The same installation procedure works fine with USB memory, but I want to use SD Card to have USB free to connect HDs.

My question: What might be wrong? I followed Martin Michlmayrs HowTos and did'nt wrote the command manually - I copied to avoid big-finger-errors - but I have'nt  success.

I hope anyone read this old thread....

Thanks,

Caesar

[Caesar]

I did it!

The only working advise was http://plugcomputer.org/plugforum/index.php?topic=968.0!

@Martin Michlmayr: Please correct your link to the uboot version 3.4.23 on http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html - yesterday there was version 3.4.24 in http://plugcomputer.org/plugforum/index.php?action=dlattach;topic=921.0;attach=153 - this uboot versio don't works with SD Card

Thanks all readers!

Caesar

Fixed, thanks.

I'm guess I'm missing something somewhere, but I can't get it... I'm also getting "Bad Data CRC" message when booting from USB.

I have tried uboot versions 19, 23 and 24 but does not help.

SOLVED!

It seems files uImage and uInitrd included in base.tar.bz2 I downloaded from http://www.cyrius.com/debian/kirkwood/sheevaplug/unpack.html have wrong md5.
