kernel building mt6582....ramblings

[aus9]

ok so I found the header but its for the wrong kernel mt6572 but still no joy
make zImage fails for a related df0* object

code tidied up so its easier to reaad

Code:

KS=MT6582-KK-KERNEL
DN=mt6582

# fix errors in Linaro bin
cd /home/gordon/android-toolchain-eabi/bin
ln -s arm-linux-androideabi-ld.bfd arm-eabi-ld.bfd
ln -s arm-linux-androideabi-gcc    arm-eabi-gcc
cd ~

# fix missing headers
cd $KS/mediatek
S1=platform/mt6582/kernel/core/include/mach
L2=kernel/include/mach
ln -s $S1/timex.h        $L2/timex.h
ln -s $S1/memory.h       $L2/memory.h
ln -s $S1/irqs.h         $L2/irqs.h
ln -s $S1/mt_irq.h       $L2/mt_irq.h
ln -s $S1/x_define_irq.h $L2/x_define_irq.h
ln -s $S1/mt_spm_idle.h  $L2/mt_spm_idle.h
ln -s $S1/mt_devinfo.h   $L2/mt_devinfo.h
ln -s $S1/entry-macro.S  $L2/entry-macro.S

I can not edit first post, but that is not important

If you are on Linux there are a number of Linaro toolchains to choose from

I chose the simplest cos I am a simple person .....giggles

click on d/l link = android-toolchain-eabi-4.9-2014.07-x86.tar.bz2

good luck

now we look to see if we can choose a different custom kernel within the kernel source

eg

#ifndef __ARCH_ARM_MACH_MT6575 visible from
/home/gordon/MT6582-KK-KERNEL/mediatek/custom/bird82_tb_td_a_kk/kernel/core/src/board-custom.h

mine is mt6582 so we can't use that one

2) Can't use same pathway for next kernel
but
/home/gordon/MT6582-KK-KERNEL/mediatek/custom/banyan_addon_x86/factory/init.rc

contents includes
chmod 0777 /dev/mt6516
and
mount yaffs2 mtd@system /system

Nope....my partition does not use yaffs nor do I have such dev

3) other one is also not mine as this pathway exist
/home/gordon/MT6582-KK-KERNEL/mediatek/custom/common/kernel/wifi/mt592x/

so I can't use "common" in my export pathway

I am no closer than before but I have eliminated all but mt6582 as potential custom kernel configs

grrrrrrrrrrr
