Archos 70b ereader / Bq Voltaire kernel compilation problem

[sady2012]

Hi, guys. Sorry for my basic English.

I have some problem with compiled/compiling kernel for Bq Voltaire - it just not working!

As you may know, about a month ago BQ has made public GPL source code for Bq Voltaire tablet accessible for downloading.

Now the issue:
-------------------------------------
Source code of linux kernel:
www mediafire com/?en5uho61k829f89

Toolchain:
git clone -b froyo git://github.com/android/platform_prebuilt.git prebuilt_froyo

What was made:

Some changes to a Makefile:

CROSS_COMPILE :=/MYPATH/prebuilt_froyo/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-

Running compiler script:

./sh_new STM7UH

The result is "kernel.img"

I replaced the original firmware kernel with the new one and all I got is bootloops...

What I am missing?

Other thing.
I'm confused about "mkbootimg" and "ramdisk-boot" files - they are for SDK2.0 ROMs

Take a look into the sh_new script:

Some video driver correcions:

cp drivers/video/logo/STM7UH/logo_stm7uh_clut224.ppm drivers/video/logo/logo_oem_clut224.ppm -f
rm drivers/video/logo/logo_oem_clut224.c
rm drivers/video/logo/logo_oem_clut224.o

Bq Voltaire .config making:

make STM7UH_defconfig

compilation:

make

./mkkrnlimg arch/arm/boot/Image kernel.img.tmp
cat kernel.img.tmp System.map > kernel.img

It's very close to the result of rkunpack usage:

• boot.img
  kernel.img
  kernel.img-raw
  kernel.img-symbol
  misc.img
  recovery.img
  system.img

kernel.img-raw - compiled non-packed kernel (arch/arm/boot/Image)
kernel.img-symbol - symbol table used by the kernel (System.map)

We can make kernel.img with two files:

./mkkrnlimg kernel.img-raw kernel.img-signed
cat kernel.img-signed kernel.img-symbol > kernel.img

So, kernel.img format is correct, all we need to do is run ./sh_new STM7UH

What am I doing wrong?

• arm-eabi-4.4.3 - bootloops
  arm-eabi-4.2.1 - can't compile
  arm-eabi-4.3.1 - can't compile
  arm-eabi-4.4.0 - bootloops

Any suggestions?
