Hello,
I am trying to use buildroot to create a rootfs (specifically a
initramfs) that I can incorporate with the Xilinx linux kernel (2.6...).
I am able build properly, I have the rootfs becoming a cpio.gz and the
initramfs is enabled. I then take this pass it to the linux kernel
build environment and get a single elf file. When I run this I get the
following problems:
Bootline: Linux/PowerPC load: console=ttyS0 ip=on
Bad trap at PC: 4801f1b4, SR: 2d000, vector=2010
Bootline: Linux/PowerPC load: console=ttyS0 ip=on
root=/dev/ram
Bad trap at PC: 4801f1b4, SR: 2d000, vector=2010
I then tried to just get to a shell by doing the following:
Bootline: Linux/PowerPC load: console=ttyS0 ip=on
rdinit=/bin/sh
Bootline: Linux/PowerPC load: console=ttyS0 ip=on
root=/dev/ram rdinit=/bin/sh
Bad trap at PC: 4801f1b4, SR: 2d000, vector=2010
init has generated signal 5 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!
Call Trace:
[cf831d80] [c0005f88] show_stack+0x48/0x15c (unreliable)
[cf831db0] [c0220c80] panic+0x94/0x174
[cf831e00] [c0038490] do_group_exit+0x0/0xb8

[cf831f40] [c000e8c0] ret_from_except_full+0x0/0x4c
Rebooting in 180 seconds..
First, do I need the root=/dev/ram line?
Second, does anyone know what signal 5 is and if it is an error in my
configuration of BR? I think it is this because I can "boot" with
another initramfs image (see:
http://www.aclevername.com/articles/linux-xilinx-tutorial/minimalist-ini
tramfs.html).
Any help would be really great! Thanks in advance!!
