stubs_min.S
DEF(physw_status, 0xC624)//--->fixed

The values is 0xCEF8 in a480,I search the 0xCEF8 from a480's firmware.
and at the same code place in a1100's firmware,the value is 0xC624.So I use it.

I am losing track what the current version of your keyboard code is.

Can you list it again ?

For now, I would use :

dst[2] = *mmio2 & 0xffff;

Code: [Select]
void kbd_fetch_data(long *dst)
{
    volatile long *mmio0 = (void*)0xc0220200;
    volatile long *mmio1 = (void*)0xc0220204;
    volatile long *mmio2 = (void*)0xc0220208;

    dst[0] = *mmio0;
    dst[1] = *mmio1;
    dst[2] = *mmio2 & 0xffff;
//  dst[2] = *mmio2;
}

void my_kbd_read_keys()
{
kbd_prev_state[0] = kbd_new_state[0];
kbd_prev_state[1] = kbd_new_state[1];
kbd_prev_state[2] = kbd_new_state[2];

    _kbd_pwr_on();

    kbd_fetch_data(kbd_new_state);

if (kbd_process() == 0){
// leave it alone...
physw_status[0] = kbd_new_state[0];
physw_status[1] = kbd_new_state[1];
//physw_status[2] = kbd_new_state[2];
    //  if(imgbuf)physw_status[2]  = physw_status[2] | menu_key_mask ;  ----->no imgbuf
} else {
// override keys
physw_status[0] = (kbd_new_state[0] & (~KEYS_MASK0)) |
  (kbd_mod_state[0] & KEYS_MASK0);

physw_status[1] = (kbd_new_state[1] & (~KEYS_MASK1)) |
  (kbd_mod_state[1] & KEYS_MASK1);

// physw_status[2] = (kbd_new_state[2] & (~KEYS_MASK2)) |
//   (kbd_mod_state[2] & KEYS_MASK2);
}

    _kbd_read_keys_r2(physw_status);

remote_key = (physw_status[2] & USB_MASK)==USB_MASK;
      if (remote_key)  remote_count += 1;
else if (remote_count) {
usb_power = remote_count;
remote_count = 0;
}

if (conf.remote_enable) {
physw_status[2] = physw_status[2] & ~(SD_READONLY_FLAG | USB_MASK);
}
    else physw_status[2] = physw_status[2] & ~SD_READONLY_FLAG;

    _kbd_pwr_off();

}
with this code,The camera can turn on with sound.
When I press some key of the camera
the digit on the screen have some changes
one case:
physw_status[1]                  --->    2       c21ffeb(when I press the left key,I change to c21f7eb, press right key change to c21fbeb)


I can trun on the mode to let the lens out.But can not take picture.And at this time,any key is disable.But the digit on the screen is changed when I press the key.

As a matter of interest, connect the camera to the PC using the USB cable.

Make sure conf.remote_enable is true.

Does a programme on the PC startup ?

It should not.

Do any bits of physw_status[] change ?

I meant when you connect to the PC while in shoot mode, what happens ?

Anyway, try changing if (kbd_process() == 0){

to

// if (kbd_process() == 0){
if(1){
