Just tried it: oocd: > stm32x mass_erase 0 > reset init gdb: (gbd) tar rem :3333 (gbd) load (gbd) mon gdb_sync (gbd) stepi (gbd) info reg ... sp 0xfffffffc 0xfffffffc lr 0xffffffff 4294967295 pc 0x80002dd 0x80002dd <Reset_Handler> So the PC is set up by GDB (assuming the entry point has been set correctly in the elf-file) but nothing touches the stack pointer. And sure enough: (gdb) stepi -> target is off to infinity and beyond (first instruction pushes some registers) _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
