hello,
I am studying the source code of Haret and I am compiling new kernels of
linux but I can`t boot the linux.
the half (light) coloured-dotted screen is similar to:

The problem is that the kernel lapel the frame buffer.
Frame buffer (P550) is in 0x300a0000 - 0x3019f000
My default.txt
set mtype 1389
set kernel "zImage"
set ramaddr 0x30200000
set cmdline "root=/dev/ram0 rw noinitrd ramdisk_size=16384 mem=64M
console=ttyS0"
bootlinux
You need:
The datasheet of s3c2440a cpu.
http://www.embedinfo.com/english/download/s3c2440.pdf
Configuration GPIOS,....
Port linux to new pocket pc is very dificult. The work is very slow because
in Internet don't exist hardware information about our pocket pc. You can
use Haret. You can dump the memory register and you can search information
about the hardware. You must read the datasheet.
You could dessasambler you P350 and you will view all microcontrollers and
you will view the connections. I don't disassemble my P550 because It is in
guarantee.
I hope that i can help you.
Bye.
