Hello Luca,

This is going to be my last mail today as it's getting close to my bedtime! I wish you luck and I'll be checking the list tomorrow, as well as continuing to experiment with the initramfs, when I have time.

Waiting 10sec before mounting root device...

The 'rootdelay' parameter forces this pause; as far as I know, it's only necessary for slow boot media, such as if you were booting over USB or serial connection. 10 seconds is a bit long, even for that. This makes me wonder if it's possible to boot the hx4700 over an infra-red PPP or SLIP link (that's a crazy idea - you can tell I've been awake for ages!).

UFS: Cannot open root device "mmcblk0p2" or unknown-block(254,2)
Please append a correct "root=" boot option
Kernel panic - not syncing: UFS: Unable to mount root fs on
unknown-block(254,2)

'unknown-block(254,2)' = /dev/mmcblk0p2 - second partition on the SD card.

In startup.txt.bootimage, I had set

---
set cmdline "root=/dev/mmcblk0p2 rootdelay=10 console=ttyS0,115200n8
console=tty0"

This should be something like:

set cmdline "root=/dev/ram0 console=ttyS0,115200n8 console=tty0 rdinit=/sbin/init"

The 'rdinit' parameter depends on whether you want to use a /linuxrc startup, or another program. I set mine to /sbin/init because I'm using the standard sysvinit.

Cheers,

Lex.
