Title: trouble booting A1 with Kernel 2.6.x
Post by: Agafaster on February 02, 2008, 10:05:38 PM
I've tried both kernel 2.6.60.x and 2.6.8 from Ross Vumbaca's page.

I can use RawDisk to squirt the kernel into my Boot partition (RDB disk) which is MDH3B: (effectively a linux dd command in OS4).
however, once I'm in UBoot, and enter Diskboot 500000 0:3 0
and then type Bootm the boot process fails with a bad CRC error on both the 2.6.x kernels. Am I forgetting something ?

I don't think those kernels can be booted from a dedicated partition anymore. A standard file copy to the /boot directory of your Linux partition should do it. You'll need to create the file a1boot.conf (also lives in /boot) and use the standard Amiga multiboot method in U-Boot. A list of Linux configs should appear after the OS4 options.

An example a1boot.conf:
Code: [Select]
Sarge-2.4.26 /boot/kernel-2.4.26.img root=/dev/hdb2 video=radeon:1024x768-8@70 l2cr=0x80000000 ide=nodma

That's for the old 2.4.26 kernel, obviously. Arguments will be different on the newer ones.

It should be all one line. The syntax is
Code: [Select]
[config name] [path to kernel] [arguments]

And it really hasn't been made clear, but these new kernels might require a hardware-fixed A1 - the USB and IDE/Ethernet DMA corrections.

Magic, thanks for the advice !

Hmm. I'll just have to find out won't I .. mine is an unfixed (afaik) A1 - at least the USB seems to be unfixed (but workable ;-) )

worked an absolute charm, thanks for the advice !
Just a few tweaks now (couldnt remember the format for the video card parameter, etc) then I can try to upgrade Debian Woody to Etch 4.0

Cheers Matt_H !
