Angstrom & OpenZaurus / Sound Card Problem: Must Be 44.1khz ...

« on: November 30, 2006, 08:49:30 am »

I have a akita and installed hentges ROM on it.

For play SFC games, I compiled libsdl with fb support on (qpe support off) and snes9x.
With the QVGA support in Linux kernel  2.6.17, the video side is very good. But the sound side doesn't work.
(In Linux 2.6.16 of OZ 3.5.4.1, the sound works good, but the video is too small).

But the music can be played properly under Linux 2.6.17. So sound card driver can work, at least under some
specific condition. I try a sound wave file with 8 bit, 11025 Hz, and the it can not be played by mplayer.
So I think the sound card can work only under certain condition.

Then, I modified the snes9x, make it use 44100 Hz instead of 22050 Hz, and now I can play SFC games on
my zaurus perfectly (except the cursor, which is always there).

Why the sound card can not work in 22050 Hz?

Angstrom & OpenZaurus / Kexec For 2.4.x/arm

« on: March 08, 2006, 12:28:08 am »

Hi! everyboy.

I implemented the kexec for Linux 2.4.x/arm based on the bootloader of OpenBSD.

It can be used to boot another kernel(such as 2.6.x) within the 2.4.x kernel, and it is useful for somebody who want to test the 2.6.x kernel without flush the flash.

Caution:
  Not very security. I have ever corrupted my jffs2 root file system on nand flash with this. Turn off the MTD support on booted kernel.

Usage:
 make KERNEL_SRC=<some place>
  copy vmlinux to the directory of kexec.
 modify bootlinux
 ./bootlinux

Hope helpful for somebody.

Best Regards.

Thank you for you replay.

I try openzaurus now and use rboot to use mmc card as root file system.

Sharp ROMs / Source Of Root File System Of Sharp Roms

« on: March 04, 2006, 11:15:25 am »

Hi! everyone.

I buy a zaurus c1000 recently.

Because of the write number of flash is limited, I want to mount the /home file system on a image of mmc card. But when I do this in /etc/rc.d/rc5.d/S01mounthome, the system can not boot up. I think the booting up process of sharp rom perhaps do something for sd card or /home so that the /home mounted on a image of mmc card can not be used.

I go to http://developer.ezaurus.com, but can just find the source of kernel without source of root file system. Where can I find the source of root file system for C1000.

Best Regards.
