Yes, I can start an rtems image (RTEMS 5.1) on beaglebone (bboted by tftp in u-boot):
*** HELLO WORLD TEST *** executing thread name: (Sep 10 2018 - 19:41:39 -0500), Build: PU : AM335X-GP rev 2.1 But it looks to me like there is no ethernet device driver for RTEMS5.1 and LEGACY_STACK available. So I can't use Ethernet here. So I have to switch to libbsd. I will now try again with RTEMS-master (6). Viele Grüße Heinz Junkes -- Experience directly varies with equipment ruined. > On 1.
