Advanced Boot Copier -

Hi,

Advnaced Boot Copier for CFI Flash memory loads and jumps to a simple application (Hello World code). But it fails to run a "larger" application. The boot copier successfully validates the application using "CRC32". It loads and copys "successfully" into RAM. But somehow the application fails to run. Anyone has any ideas that what might go wrong? Please give me some hints/helps.

Thank you,

OnePlusOne

    I passed that. But I could not recall what exactly was the fix. It has been for a while and I am not using that boot loader for now. I believe there is something to do with the interrupts.

    Yeah thats what I think I'm seeing... seems like when the bootloader writes the new image over it's interrupt table the whole deal goes out to lunch even tho there is a alt_irq_disable_all (); thrown in...
