 |
|
Thanks to the good help in the LiveCD thread and #gentoo-mips, my O2 (R5K, 200MHz, 256MB) is now booting a self-compiled kernel happily from the harddisk. Using mips-sources-2.6.9-r3 and arcboot-0.3.8.4-r1.
However, if I set the framebuffer memory to 6 or 8 MB then the boot fails
after arcboot has loaded up vmlinux. The last thing that gets printed out is "zeroing memory". The O2's led blinks red and its game over. With 4MB it works fine.
Ideas? Known bug?
Also, what framebuffer settings work well with X11? I'm having trouble getting a sane colour map in X.

but I have compiled a kernel with 4 MB FB and still get the flashing red light after zeroing memory and booting kernel.
could you post your .config file?

With 4MB FrameBuffer configured, setting "DefaultColorDepth" to 15 in xorg.conf (xorg version 6.8.0_r1) works.
Do not know why. Other configurations just messed up.
Thanks Andy aka squawker for your kernel config file. I slightly modified it with menuconfig, then my cute O2 is now booting with a natively compiled 64bit kernel.
 Now I am wandering where can I get a working sound patch for O2? |

That seems to fix my problems to. Thanks to the quys at #gentoo-mips and Andys .config file I also got the O2 to boot nicely with a 64 bit kernel. The current sound patch seems to work only with 32-bit kernels so lets see if somebody makes a new one. And there is also the HIGHMEM issue to be fixed. It would be nice to be able to use the 1GB of RAM in my O2.
