It will only show output on the very first run of the programm. Running it again will show no further output. To make it worse there seem to be two bugs: SWIWrite (from armos.c) is only called after the first "run" after "load". "run" again after a finished inferior will not call SWIWrite again. This is workaroundable by calling "load" again, but then at the second run the file descriptor is wrong: armos.c: res = sim_callback->write (sim_callback, f, local, len); this will call through callback.c os_write where a call to fdbad will return -1 and set error to EBADF because p->fd_buddy[fd] < 0 Until a real fix (the simulator seems to be not reinitialized well) sim_callback->write_stdout (sim_callback, local, len); can be substituted for the write. But this still only works on the first run. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
