<p class="MsoNormal">To make sure something isn’t horribly broken in RTEMS with regards to the BBB, I ran the RTEMS test suite on the BBB and it seems to work as expected. Out of 597 tests 572 tests passed including hello.exe. This is the latest RTEMS 5
build tree.<o:p></o:p></p>

<p class="MsoNormal">I don’t have any experience with rtems-boot-image unfortunately so I’m not much help there. I used objcopy and mkimage to create an image loadable on U-boot via tftp.
