JULY 2010

• Part of the work done for kernel A 2.6.24.3 also works for B 2.6.31.3 kernel. Made two topics here.
• Update based on miniport of kernel work from linuxtogo.org (svn version 33). This is a partly working kernel 2.6.24.3.
• Addtional effort to rewrite some sources is done and maintained by Nikolaus at http://projects.goldelico.com/p/letux-400/

• try for debug purposes herewith the steps I made to make these preliminary kernels to work on trendtac epc700.

A patches 2.6.24.3 kernel for ingenic jz4730

• a) ingenic's toolchain: ftp://ftp.ingenic.cn/3sw/01linux/00toolchain/mipseltools-gcc412-glibc261.tar.bz2
• b) kernel source package ftp://ftp.ingenic.cn/3sw/01linux/02kernel/linux-2.6.24/linux-2.6.24.3.tar.bz2
• c) ingenic patches ftp://ftp.ingenic.cn/3sw/01linux/02kernel/linux-2.6.24

• 1A) Extract linux-2.6.24.3.tar.bz2 with: tar xvjf

• 2A) cd linux-2.6.24.3 dir

• 3A) patch ingenic_2010304 with:
• patch -p1 < ../linux-2.6.24.3-jz-20100304.patch

• 4A) patch with modifications from letux-400 (excluding rtc part) and minibookversion33 (excluding yaffs2 part):
• patch -p1 < ../patchminibookRV10

• 5A) make trendtacRV10_defconfig

• 6A) make uImage

• 7A) make modules_install

• 8A) copy kernel modules /lib/modules/2.6.24.3 to SD ext3 (partition2)

• 9A) Copy uImage to SD card FAT32 (partition 1) and your linux distro to ext3 (partition2)
• You can startup from SD by pressing left fn , shift , crtl + press any key to boot from sd partition 2
• Keep F2 pressed = startup from /dev/mmcblk0p2. F4 = nand (default) F5 = /dev/mtdblock5

• 10A) If the kernel is good enough you could install it on your nand by:
• cat uImage > /dev/mtdblock1

B patches 2.6.31.3 kernel for ingenic jz4730

• d) kernel source package ftp://ftp.ingenic.cn/3sw/01linux/02kernel/linux-2.6.31.3/linux-2.6.31.3.tar.bz2
• e) ingenic patches ftp://ftp.ingenic.cn/3sw/01linux/02kernel/linux-2.6.31

• issues 2.6.31.3RV113:
• - jz_eth0 nok. very slow and instable.--> quick fix in 2.6.31.3RV114 uImages, sourcefile jz_eth.c included below.
• - short blink/scramble lcd

• 1B) Extract linux-2.6.31.3.tar.bz2 with: tar xvjf

• 2B) cd linux-2.6.31.3 dir

• 3B) patch ingenic_2010304 with:
• patch -p1 < ../linux-2.6.31.3-jz-20100304.patch

• 4B) patch with modifications from letux-400 (excluding rtc part) and minibookversion33 (excluding yaffs2 part) + quick rework:
• patch -p1 < ../linux-2.6.31.3RV113.patch UPDATE add root_delay=5; in do_mounts.c (prepare_namespace)

• 5B) make trendtacRV113_defconfig

• 6B) make uImage

• 7B) make modules_install

• 8B) copy kernel modules /lib/modules/2.6.31.3 to SD ext3 (partition2)

• 9B) Copy uImage to SD card FAT32 (partition 1) and your linux distro to ext3 (partition2)
• You can startup from SD by pressing left fn , shift , crtl + press any key to boot from sd partition 2
