Hi,
after the (usual) long delay I've managed to fight my jet-lag with a good
coffee and I've tested the image Arnaud provided me with :)
The steps I've followed are:
1. halt the startup sequence at Redboot> prompt with CTRL+C
2. *RedBoot> fis load ramdisk.gz*
3. *RedBoot> load -r -v -h 192.168.1.122 -b 0x01008000 -m tftp
zImage_2633_iop32x_defconfig*
(since Redboot comes up preconfigured with an IP address I've chosen
tftp)
This step ends with the following message:
*Raw file loaded 0x01008000-0x01279aaf, assumed entry at 0x01008000*
4. *RedBoot> exec -c "console=ttyS0,115200 rw root=/dev/ram0 init=/linuxrc
initrd=0xa1800000,8M mem=2...@0xa0000000 force_ep80219"*
At this point the startup sequence goes on pretty normal until it stops with
errors (RAMDISK) eventually terminating in a kernel panic (full sequence is
attached).
What's the meaning of the hex addresses in the above commands? Are they
hardcoded in the image or do they just point to (almost) arbitrary
addresses?
Thanks,
-mw
