blind porting is a challenge
  8) yes indeed it is,
some of the stuff is deductive work like finding the stubs and coping code from the firmware for boot, captseq.....

But as a first step porting is possible, but someone needs to do the testing!

@Bernd R

I Include the sentences from reyalp, for testing only at camera.h for your cam, replace it in the includes directory

get it here http://es.drop.io/asm1989

then you can use
ASM_SAFE( ".....")   inside your  asm volatile (

A romlog http://chdk.wikia.com/wiki/Canon_Basic/Scripts/Romlog may also provide some clues

yes Bernd R , a romlog could help to trace it , it's better to have a small spare SD card for this, since you have to manually change some bytes of the card, follow the realyp link for the details,

 and try to get a romlog file just after the crash.

ok, it try V4 and after
    "BLLT    sub_FF815FD4\n"       //Mising err_init_task

i add a bl blink

and i do romlog soon.

today i find some more maybe intresting information.when the accu show on normal camera use (lens are out) 2 bars(mean 66% full) and i call update the firmware menu (with the testcode in V3 above) i get a message on the camera display "replace akku" (text is diffrent language, so i do only a weak translate.).i test this 2 times and the accu message happen always on firmware update immidiatly

after i charge accu a little (20 miniutes), then crash happen as before( no accu message come), i do also call the menu factory settings load, but it do not help.

that register trashes by C functions i know, and so i call only the blink code as last funtion and the camera never leave the function so it doesnt matter if a register is trash.the blink only show if a codeplace is reach.I remove after every test after 10-15 sec the battery to reset to original firmware.


I get in mind if nobody know whats the problem is, its best then to copy the ixus 1000 firmware code original in GCC and get it working.

and if that work, merge the chdk code in.so can see what chdk code bring the problem.

I get also a romlog.txt file.My clock is set correct, but as can see in the Date it happen not today.
I remember when i buy the camera new, i test and i get once a crash without chdk.this seem store in log.

also when i use new chdk file without blink before, i must remove battery, and insert the card with the script.but seem the log is battery remove safe.

also remember that this text output is not show on display.

 LCDMsg_SetStr(a,"done")

or maybe there need add a delay command so this can read


I use this script

private sub Initialize()
  UI.CreatePublic()
  a=LCDMsg_Create()
  LCDMsg_SetStr(a,"Get ROM Log to file")
  System.Create()
  GetLogToFile("A/romlog.txt",1)
  LCDMsg_SetStr(a,"done")
end sub

Bernd R,

This romlog seams to be from a script execution if you trace back in the asm code 0xFF892258 -> 0xFF892188 .....

to trace the actual error compile with v3 or v4 with out blink stuff, and inmediatly after the crash:
1.- Open the battery door
2.- Insert the sd card with the romlog script
3.- close the battery door
4.- start in play mode, preess set
5.- open the battery door
6.- remove the card and copy with a sd card reader the romlog file

-> Regarding creating the boot.c file
It will help to join develop,  if you have disasembled the firmware in ida or something like it , and processed with the chdk idc scripts...

i am sure i have only after 10. day of october begin with chdk script.so this was a problem in original firmware.have you find what address the assert function of Ixus 1000 is ?
maybe when call instead of blink assert, this give more info ?

this i have do, the blink code is not execute(i try also a version without it) and the romlog i get is always same from 5. day of october.

I see that IDA is a commercial product which cost around 500$.in the wiki to dissasemble Firmware stand version 5.2

Is the 4.9 freeware version also able to reassemble the cannon firmware dumps ?
