Hoozah! minimum.exe is supposed to reflect the smallest application you can have. It barely qualifies as an application as the Initialization task exits from the thread body and that's what triggers the fatal error. It is expected so that's a pass. Unfortunately, the exception frame you posted to Discord has what looks like a mistake in printing the idle thread id (see name on next line): *** FATAL *** fatal source: 0 (INTERNAL_ERROR_CORE) fatal code: 5 (INTERNAL_ERROR_THREAD_EXITTED) RTEMS version: 6.0.0.ee92899632c823e19aa4f2e7048af3d910f59be2 RTEMS tools: 12.1.1 20220622 (RTEMS 6, RSB eea379370116628dbe91f19e61ad6129aa1951ac, Newlib ea99f21) executing thread ID: 0x089010001 <==== executing thread name: IDLE Kinsey can you run this on one of the aarch64 bit targets you have? I suspect this is not a Pi specific issue but maybe something in printk? Or the printf format specifier used. Once more is known, this likely will need a ticket. Try the fileio, cdtest, nsecs, and paranoia samples next. If those look ok, it is highly likely that most of the single processor tests will run. fileio requires working console input. > > Here's my setup for running RTEMS6 on RPi4B: > > TF-A is required to enable GIC on RPi.
