I am trying to use OpenOCD with GDB to debug C code running on a Cortex A8
(AM335x). One of the issues I am running into is the MCU jumping to the
ISR vector every time I try to step using GDB, which results in stepping to
the ISR vector rather than the next line of code in the current source file.
If I do a “mon reg cpsr 0x1d3” from the gdb command line to
disable IRQ’a , then the stepping works. Obviously, this is not the
correct way to do this.
So the general question is, is there a way I can step through code without
gdb jumping to the ISR vector?
An alternate question, and maybe be related is: Does the OpenOCD cortex A8
module have anything like the M3 maskisr functionality that I can hook into
GDB?
Thanks,
Ken
