[uClinux-dev] romfs help?

[Brandon Fosdick]

Alright, I've given up on romfs. I've switched to using initramfs and a 
cpio archive. Now the kernel says it's mounting the filesystem, but it 
seems that it can't find anything in it. I get the warning about not 
opening an initial console, a kernel panic, and then it can't find init. 
Any suggestions?

The cpio archive has a /dev/console and a /sbin/init and works just fine 
with a 2.6.11 kernel.

Here's my cmdline:
---
CONFIG_CMDLINE="rootfstype=ramfs initrd=0x812000000 keepinitrd 
console=ttyS0"
---

and here's the boot output:
