OK, I have been given conflicting information about this so I will take your word for it

Strange that the capture-sequence has to work just to power-up the camera.

Because that file contains one of important task procedure created on camera startup.

Small hint: if kbd.c, capt_seq.c, movie_rec.c are not rewritten yet, in file platform/<camera>/main.c simply disable lines:

// *entry = (long)physw_hook;

// *entry = (long)capt_seq_hook;

// *entry = (long)movie_record_hook;

Thanks, I will try that to save time.

Big hint !

We now have the splashscreen displayed and the CHDK folder and sub-folders created.

(apparently the splashscreen was covered in 'bands').

I guess that I now have to get the keyboard working somehow.

Great!
I see that keyboard is very similar to other cameras, but not uses kbd_pwr_on() and kbd_pwr_off() functions....

Well, I enabled the create keyboard task and of course the camera crashed and locked-up.

For no particular reason, I use the ixus55 kbd.c.

So, what do I do now

It seems that kbd.c from A570 is better solution.

Please check in CHDK following ROM addresses:
0xFFA433D0 kbd_p2_f
0xFFA42FB4 kbd_p1_f_cont
0xFFA4457C kbd_read_keys_r2

And RAM adresses:

physw_status 0x64E00
physw_run 0x8738

Do no use kbd_pwr_on() and kbd_pwr_off() function, because TX1 do not have it.

If camera boots, enable showing of "misc values" in OSD and adjust keyboard map and KEYS_MASKn by pressing all keys.
