If you do not see the second blink, the camera dies before boot.c
You can try to comment out "MOV R0, # 1 \ n" in loader / main.c
Or wait for some advice from more experienced people.

Code: [Select]

        //"    LDR     R0, =sub_FF020000 \n" 
        "    MOV     R0, %0\n"              // new jump-vector
        "    BLX     R0 \n"
//        "    MOV     R0, #1 \n"        
        //"    LDMFD   SP!, {R4,LR} \n"  
         : : "r"(MEMISOSTART) : "memory","r0","r1","r2","r3","r4"
        );

tried removing MOV R0,#1

still the same

Can you attach the source that changed since the latest published source zip?

Here you go.

Thanks.
In code_gen, move the CHDK_NOT_IN_CANON_HEAP related modification block of boot.c down so it replaces this (0x2B9464 is MEMISOSTART):
LDR R0, =0x2B9464

the camera no longer freezes

the AF LED turns on , turns off
there is a very small period it turns on then immediately turns off ..... maybe a few milliseconds... you could almost miss it

but the camera does not freeze

if i press the power button again it repeats the process
