7.I add all of them in to stubs_entry_2.S, with dummy values 0x12345678.
Like this
NHSTUB(AllocateMemory,0x12345678)
These functions are required for CHDK to function. You need to find the correct addresses.

Hi guys!

Hi xiaofeng! You Chinese? Last year I made a journey in China. It was a wonderful trip! I visited Beijing, Qingdao, Shanghai, Hangzhou and Sanya. The Chinese kitchen is very delicious! Your country is very beautiful!

My English is not good too.

I bought this camera today. I'm happy! :)

Not clear if you have done this, but all the ASM in boot.c needs adjusted for each camera. Most needs to come for your own cameras firmware, not another port.

Maybe you have some English speaking friend who can help you understand http://chdk.wikia.com/wiki/Adding_support_for_a_new_camera ?

Frankly speaking,I can understand the "Adding_support_for_a_new_camera" only 60%.
Some words I must read many times then understand.
If there is a chinese version,I think I will do fast.

As you say,may be the reason for camera freaze is copy.I have not adjust the asm code yet.I copy these file from a480.So I will try to change it later.
Thanks to reyalp.But today I will suspend temporary.Just because Gril friend coming.

Usually the ASM code is copied from your cameras firmware dump. You cannot use the code from another camera, all of it needs to corrected for your specific camera.

When I test the led status.I get confused.
Here is my startup() code.
the led  light forever.So what's meaning?
Code: [Select]
int gk;       
*((volatile int *) 0xC02200DC) = 0x46; // Turn on LED
for (gk=0; gk<0x1000000; gk++) // Wait a while
{
     asm volatile ( "nop\n" );
}


long *bss = &link_bss_start;
long *ptr;

// sanity check
if ((long)&link_bss_end > (MEMISOSTART + MEMISOSIZE)){
started();
shutdown();
}

// initialize .bss senment
while (bss<&link_bss_end)
*bss++ = 0;

boot();
*((volatile int *) 0xC02200DC) = 0x44; // Turn off LED
for (gk=0;gk<0x1000000; gk++) // Wait a while
{
    asm volatile ( "nop\n" );
}
