ROM Map

[nanomad]

Unless I got everything backwards, I'm not quite sure that the FW check we have in reboot-all.c and reboot.c is gonna work with DigicV(+) cameras.

Today I discovered that checksumming from FF010000 on the 650D leads to false positives. Two cameras had a signature that was slightly different but that could run ML without issues.  Moreover, the automatic firmware dumps seems to be completely useless (ROM0 and ROM1 contain mostly 0xFF or 0x00)

Isn't all this related to the fact that the ROM base address is different?

650D.101/Makefile:ROMBASEADDR = 0xFF0C0000
6D.113/Makefile:ROMBASEADDR = 0xFF0C0000
5D3.113/Makefile:ROMBASEADDR = 0xFF0C0000
EOSM.106/Makefile:ROMBASEADDR = 0xFF0C0000
6D.112/Makefile:ROMBASEADDR = 0xFF0C0000

What about fw signature .c?

This works on 6D:

f = FIO_CreateFileEx(CARD_DRIVE "ML/LOGS/ROM0.BIN");
    if (f != (void*) -1)
    {
        bmp_printf(FONT_LARGE, 0, 60, "Writing ROM0");
        //~ FIO_WriteFile(f, (void*) 0xF0000000, 0x01000000);
        FIO_WriteFile(f, (void*) 0xf0800000, 0x007FE000);
        FIO_CloseFile(f);
    }
    msleep(200);

    f = FIO_CreateFileEx(CARD_DRIVE "ML/LOGS/ROM1.BIN");
    if (f != (void*) -1)
    {
        bmp_printf(FONT_LARGE, 0, 60, "Writing ROM1");
        //~ FIO_WriteFile(f, (void*) 0xF8000000, 0x01000000);
        FIO_WriteFile(f, (void*) 0xF8000000, 0x00ffffff);
        FIO_CloseFile(f);
    }

What about fw signature .c?

Which file?

fw-signature.h

I'm having boot up problems on 113... ti loads, draws battery icon and then freezes screen.

Would restartrestart change for new versions?

fw-signature.h

The signature in the header file is correct for my camera but wrong for another. Both camears run ML just fine and the ROM code  starting from FF0C is the same
