Hi, I have an issue with my SAM7P64 board. Let's say that the program with a blinking led is running. When i write the same program to flash with OpenOCD, the program continues running. But the again, when I flash the board using another .bin, the board freezes. Now i have to press the on-board reset button, and the new program is running perfectly. But I should be able to reset it automatically via OOCD, I don't know why it's not working.

I have a thought it might be something wrong with my startup.s/startup.c files? Or maybe it's something with the linker script? It's been adapted from AT91SAMX256 board, I can provide those files if necessary

PS. When telnet to OpenOCD server and 'poll', it says 'Target state: running' - so it's not really halted, it's running, but the led is not blinking. Also when I 'halt' the working program, PC always says something like '0x0010045c', but when I halt the other program, the PC is '0x00000010'.

Hi

The address 0x10 is the abort interrupt (often a branch to itself) so it would mean that that program is exceptioning due to an access error.
