Hi All, I'm working on an STM32 application which runs from on-chip flash, and I would like to debug it with JTAG. I prefer JTAG debugging to serial debugging from flash for a number of reasons.
Is anyone else doing this successfully? I've made the necessary kernel changes to run from internal flash and sram, and built the examples and they run fine. My app is much larger and will require some step-debugging. However, when I connect with JTAG and continue, the debugger halts at the software interrupt in hal/cortex/arch/current/src/hal_misc.c:191 __asm__ volatile ( "swi" ); And does not step/continue once it breaks there. I can step up to that point. This happens with the examples and with my app. Is there a gdb hook or OpenOCD handler, or something else that can manage this? I'm using eCos 3.0 OpenOCD 0.4.0, JTAGkey STM3210E board for now arm-eabi tools version 4.3.2 .gdbinit follows: target remote 127.0.0.1:3333 file testApp mon reset init mon sleep 500 mon poll define hook-step mon cortex_m3 maskisr on end define hookpost-step mon cortex_m3 maskisr off end mon reg pc 0x08000018 Thanks, Brian -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
