Hello

I bricked the shevaplug by installing the wrong file as uboot. I got around this and the plug now boots. However when connected to the shevaplug, after it says uncompressing  the kernel it prints garbage to the screen. Eventually it stops. After it stops I can login to the plug using putty and its ip address. Before I bricked it was booting correctly and the console was functioning

However I really want to get another version running which meets the requirements of the application. Ive been following the procedure to install to the sdcard as below.

 http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

Ive tried both lenny and squueze and the result is the same. When i run the bootm command I get


 print bootargs
bootargs=console=ttyS0,115200n8 base-installer/initramfs-tools/driver-policy=most

Uncompressing Linux... done, booting the kernel.

And then garbage on the screen and thats it. Cant login to ip address

I was going to try and install to the plug directly using

http://plugcomputer.org/plugwiki/index.php/Installing_Debian_To_Flash

However dont really want to do that yet if I just end up again with the garbage on the screen.

Any ideas. Ive attached the result of printenv from uboot. Would be happy initially to get it back to how it came booting ubuntu without the garbage to the console. Then believe the debian install may work.

Thanks

Paul

same thing that looks odd, never used it. try without the n8

Bump, does anyone have any idea what is causing the linux boot message to comes out as garbage on the console. If theres any interaction in an install it stops it working.

Thanks for the reply. Im actually using another computer now. Im certain its not the serial connection as uboot works fine, its only after its loaded the kernel and starts the linux boot that the rubbish is put on the screen. It seems that its displaying the normal linux boot messages wrongly. The plug does boot. However I cant update it as theres no way to answer any interactive questions. Plus of course the console wont work for anything other than uboot.

I'm having the same issue. My rootfs worked fine on the older models, but I got 12 new sheevaplugs and now I have this issue with al of them. I contacted globalscale about the issue and they said the CPU has changed. I'm thinking I need to use a differen't kernal now.

Garbage on bootup is likely the wrong serial baud rate. Are you using 'console=ttyS0,115200' in uBoot?

Here is an example:

I copied these setting directly from the original plug's config and put it in uboot-dflt.txt. uboot-dflt.txt had different settings.
