[ARMedslack] Hello

[Davide]

Well I checked md5sum on the 13.1 miniroot tarball and it was ok.
I got the kernel and initrd from /boot in the miniroot after extraction so I'm giessung they should be ok.

Not sure if 13.1 kernel has changed since you two tried but I can assure you that kernel gets loaded and booted but then nothing else:
7706248 bytes read
## Booting kernel from Legacy Image at 06400000 ...
   Image Name:   Linux-2.6.33.5-kirkwood
   Image Type:   ARM Linux Kernel Image (uncompressed)

   Entry Point:  00000000
   Verifying Checksum ... OK
   Loading Kernel Image ... OK
OK

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

This is the last thing that my doickstar does untill hard reset with 13.1 kernel 2.6.33.5-kirkwood

I noticed that this is not the default 13.1 kernel on x86 which is 2.6.33.4 so things may have changed since then.
I can assure you that I cut and pasted the very same instructions in order to boot from u-boot so there is ither something wrong with the kernel or something wrong with my dockstar.

Here are the instructions I'm using (which have now been saved to flash as it looks save for booting with   2.6.38rc8-kirkwood:
setenv x_bootcmd_kernel 'fatload usb 0:1 0x6400000 uimage'
setenv x_bootcmd_initrd 'fatload usb 0:1 0x1100000 uinitrd'
setenv x_bootargs_root 'root=LABEL=usbroot ro rootfstype=ext2'
setenv x_bootargs 'console=ttyS0,115200 mtdparts=orion_nand:1M(u-boot),1M at 1M(second_stage_u-boot),3M at 2M(kernel),32M at 5M(rootfs),219M at 37M(data) ro'
setenv bootcmd '${x_bootcmd_usb}; ${x_bootcmd_kernel}; ${x_bootcmd_initrd}; setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm 0x6400000 0x1100000;'
boot

This works with 2.6.38rc8-kirkwood but not with 2.6.33.5-kirkwood.
One other thing I've not checked out is if with the 13.1 kernel it's only the serial console that is dead ... but the led on the usb stick seems dead too so my giess is that there is more to it then just the serial console.

Regards 
David
