A few issues with gentoo on a Raq 2

atopo

Hi,

I'm working to get gentoo running on a cobalt raq two. Since yesterday I noticed a few issues:

- emerge mips-sources fails 'coz of a missing patch (I opend a bug report for that: 107880). mips-sources-2.6.12 doesn't have this problem.
- In the standard config the make for the kernel fails, 'coz it's trying to build with "mipsel-linux-gcc" instead of "mipsel-unknown-linux-gnu-gcc". The build works when I remove the "Are you using a crosscompiler" in the kernel hacking options, but I don't know yet if there are side effects later on.
- I have some strange behaviour with colo, using colo on the first hand (boot from harddisk) fails with a "halting" system, using colo by netboot and then using the colo on the harddisk seems to work (altough I still cannot boot my custom 2.4 kernel). I'll supply more infos as soon as I have them.

best regards
Alexander

Alright, one of the colo problem is fixed - "mke2fs -r 0" to format the boot partition with revision 0 ext2 fs did it.

Now I get this:

1> lcd 'Booting...' /dev/{mounted-volume}
1> -load /boot/default.colo
000000d7 215t
1> -script
2> lcd "Mounting hda1"
2> mount hda1
ext2: revision 0
2> menu "Which Kernel?" 50 new old vmlinux
unrecognised command
script aborted <2>

Could someone tell me why colo is in trouble? This is my default.colo:

#:CoLo:#

lcd "Mounting hda1"
mount hda1
menu "Which Kernel?" 50 new old vmlinux
lcd "Loading Linux" {menu-option}
load /{menu-option}
lcd "Booting..."
execute root=/dev/hda3 ro console=ttyS0,115200

thanks
Alexander

Hi, Sorry I didn't answer earlier -- been busy with Real Life (university). :-|

Okay... the mips-sources issue, Kumba looks after mips-sources and so you're best to bug him with kernel issues. I believe he's releasing 2.6.13 kernels shortly though -- 2.6.13.1 works just fine on my Qube2.

With the default configs, the "Are you using a crosscompiler" option should always be turned off. All it does is set CROSS_COMPILE to "mipsel-linux-".
If you wish to crosscompile using a toolchain built with crossdev, use a line such as make vmlinux modules CROSS_COMPILE=mipsel-unknown-linux-gnu-. Adapt to taste. :-)

On the /boot partition format -- it actually tells you in the handbook that it needs to be EXT2r0. Look for the bits in red. :-)

With regards to CoLo -- the menu command was replaced with the select command in version 1.16. I haven't as yet, gotten around to updating that part of the documentation -- it is on my TODO list however. :-)

On my blog, I have a post covering the issues. Essentially, that script file should be rewritten to look something like this:

Yepp, finally my RAQ boots a 2.6 kernel. There was a link missing in /dev/hda1 from boot -> .
