To the best of my knowledge, yes. The BSS section is zero-filled. The data
section was copied to RAM. Verified that with "mem" in both simulator and
Anything else that RTEMS expects to be done in start.S?
I tried uncommenting "BSP_GET_WORK_AREA_DEBUG" in bspgetworkarea.c to maybe
get some output.
After fixing the pointer-reference bugs in the code, this causes invalid
memory access in the printk routine now, in "console_outbyte_polled". So that
wasn't much help either.
