I got SAM7-P64 (using AT91SAM7S64) board and wiggler clone built by Olimex and got all software from Martin Thomas's webpage. I modified the blinking LED code to blink only one LED and built code for RAM. I am trying to use Insight debugger and OpenOcd to step through the code. After loading the code when I step through it, it does not behave right i.e. I don't see it turning on the LED. On the other hand I used HJTAG and IAR startup kit and the two blinking LED code from Twntyone (http://twentyone.blogchina.com) and there I can step through properly. Using SMA-BA I loaded the FLAS with this code and that runs fine. During the debugging with OpenOcd/Insight when I hit continue it both LEDs start blinking telling me that the FLASH code is being executed. I stated insight as arm-elf-insight -x <a .gdb file> main.elf The .gdb file has target remote localhost:3333 monitor reset monitor sleep 500 monitor poll monitor soft_reset_halt monitor arm7_9 sw_bkpts enable monitor mww 0xFFFFFF00 0x0001 I created this .gdb file following example from http://www.usbdip.de/en/armdev/index.html.
