Hi Nikolaus,
I use compiler mipsel-linux-gnu-gcc and binutils from debian sid version.
Version 4.2 and 4.3 worked fine for me.
Ingenic provided original sources and a toolchain (I think gcc 4.1 and
glibc2.61 is the minimum required toolchain to get things working).
Check source here.

Hi all,
I have also made some progress with cross-compiling the kernel.
First of all I had to solve some issues when compiling the HOST tools of Linux
(genksyms etc.) on Darwin since there are some assumptions about availability
of header files. This resulted in missing malloc.h and optargs...
Now the kernel compiles mostly, emitting approx. 20 warnings about
uninitialized variables e.g.
drivers/scsi/scsi_lib.c: In function `scsi_alloc_sgtable':
drivers/scsi/scsi_lib.c:708: warning: 'index' might be used uninitialized in
this function
drivers/scsi/scsi_lib.c: In function `scsi_free_sgtable':
drivers/scsi/scsi_lib.c:708: warning: 'index' might be used uninitialized in
this function
drivers/scsi/scsi_lib.c:708: warning: 'index' might be used uninitialized in
this function
and some other minor issues.
But then I get:
SYSMAP System.map
SYSMAP .tmp_System.map

Please report this bug.
Oops... When I look into the head.S line 86 it is:
.comm .stack,4096*2,4
Anyone knows incompatibilities? I use gcc-3.4.6 and binutils-2.16

Hi,
Some additional info from my debugging of the mini-book 2.6 kernel sources.
Attached a zip file from my trial CONFIG file.
First step: copy CONFIG_X to .config
Second step: you need to run make oldconfig. and enter untill end of file.
Third step: make uImage.
Optional: make modules
The standard kernel will stuck at boot due to no startup rootfs. I changed the
do_mounts.c to boot from /dev/mmcblk0p2. See issue 5.
If you hook up a serial port via cutecom or minicom you can see the console
commands (my output is included in zipfile)
Check http://projects.kwaak.net/twiki/bin/view/Epc700/SerialConsoleHowto.
Updates from the five previous issues:
1) Issue with sound, the driver i2s jzsoc is loaded, I modified the
/sound/oss/ak4642en.c GPIO items to be the same as the skytone one.
This only works with esound stuff (esd, esdplay will work). SDL, X11 and audio
mixer isn't able to run. (get a message from kernel that audio is busy or
unsupported channels)
2) Issue with shutdown. no update
3) Issue with touchpad buttons. no update.
4) Solved. If I want to compile modules for the angstrom kernel. I disable
CONFIG_PREEMPT and add softfloat compiling to gcc. add -msoft-float in the
makefile at LD and CC compiling.
5) Issue with my own kernel. Have found a work-around for this. I modified the
do_mount.c
if (saved_root_name[0]) {
// root_device_name = saved_root_name; << commented this part out
root_device_name = "/dev/mmcblk0p2"; << and added this one, to
load from my second SD ext3 partition.
Any advice for issue 1-3 ?
