The camera can turn on and off correct.
But if I hook the mykbd_task.Then camera can power on and off correct.But the screen has nothing on it.Any key except power and play back have no response.

SD card lock override is in kbd.c, mykbd_task.

If you run without kbd task do you get CHDK OSD ?

If so, use debug display (core/gui.c gui_draw_debug_vals_osd()) to show bits of physw_status, maybe kbd task is overriding wrong bits.

CHDK shows a simple splash screen if it can't find the logo. Logo goes in CHDK/data/logo.dat

Anyway, if you see simple splash, you should be able to display debug information, but you must do it in code because you have no controls until you get kbd task working.

I only hook the kbd task.But after do that.The screen has nothing.camera power on,then lens come out.Any key have no response except the power and playback button.
I do not know why the screen have no message?If I do not hook the mykbd_task.The camera can power on.I can see the chdk logo.

There is something wrong with your kbd task, you need to debug it. Very unlikely anyone can know what the problem is with just a description.

kbd.c in the platform directory handles the phsw_status bits (buttons, usb power, card lock) and also calls the core/kbd.c stuff to send button presses to CHDK and run script.
