Hack A10 Devices
This page describe how to hack a A10 powered tablet and let a custom kernel to run on the tablet. The work was done on an Ainol Novo 7 Advanced tablet. But should be working on all A10 based tablet. Since A10 can boot from usb, never worry about bricking your device.
The stock firmware in my Novo7 is android 2.3.4. With android adb i can log into the device and take a look at inside.
# mkdir /sdcard/nanda # mount -t vfat /dev/block/nanda /sdcard/nanda # ls /sdcard/nanda boot.axf boot.ini drv_de.drv font24.sft font32.sft linux os_show script.bin script0.bin sprite sprite.axf magic.bin # ls /sdcard/nanda/linux bImage linux.ini params paramsr recovery.ini # cat /sdcard/nanda/linux/linux.ini [segment] img_name = c:\linux\bImage img_size = 0x2000000 img_base = 0x40008000 [segment] img_name = c:\linux\params img_size = 0x100 img_base = 0x40000100 [script_info] script_base = 0x43000000 script_size = 0x10000 [logo_info] logo_name = c:\linux\android.bmp logo_address = 0x48000000 logo_show = 1
As you can see the linux/bImage is our kernel, and the linux/linux.ini is a config file that some loader reads, and load the file bImage to 0x40008000 address. And the file linux/params is the kernel cmdline.
# cat /sdcard/nanda/linux/params console=ttyS0,115200 root=/dev/nandb rw init=/init fbmem=32M@0x5a000000 loglevel=8;
And recovery.ini and paramsr is for android recovery boot and cmdline.
