But it didn't complain about anything, it's not possible to tell from this output if programming failed or not. Since you're using GDB anyway can you try "load" and then "compare-sections"? And when you're using "program" can you add "verify" parameter to its options so we see if anything at all was written? Are you sure flash wasn't somehow "protected" or "locked" by firmware itself or other tools? Does erasing flash work? On the hardware I had access to I did many tests and flashing was indeed functional so I'm quite confused by your results. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com
