If I correctly understand your reference to porting the HAL, is it possible that this is not complete. e.g. if cyg_hal_invoke_constructors() is not called, you'll see things like crash/reboot when the idle thread should run. (All other threads blocking) We're finishing off our first board port now, and find (as usual) that there's no substitute for an ICE, even if only JTAG, so that reasoning can be based on some hard evidence. Incidentally, we're not using redboot, so the answer to the question asked in the subject line is: Yes Erik -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
