Before trying it with rtems-run and rtems-test I tried manually loading it in the simulator. But gdb doesn't respond as soon as I execute the run command. The only way to exit it was using ctrl-c and GDB responds with sim_events_schedule_after_signal - buffer overflow Quit Aborted (core dumped) I tried setting breakpoints within GDB but it never seems to hit them. I tried running the examples through rtems-test results in ta imeout. Due to the slow internet connection and slow development machine, I could only build and test a few BSPs. In case if anyone has an already built tool suite and BSP for the mentioned arch please try them out. BTW: Did I mention adding these to tester, or did I mention creating > build sets for them?
