What happens when you reduce the memory space for the mbufs to 4MiB? What is the
"RTEMS work space"?
By "RTEMS work space" I mean the space between bsp_section_work_begin and
bsp_section_work_end, which I assume is handed over to the unified work space. I also assume
allocated "libbsd" data structures come from there.
Yes, the space between bsp_section_work_begin and bsp_section_work_end
is used for the heap which is used by libbsd.
After reducing the space for the mbufs I still run out of RAM. I've been
patching rtems_bsd_allocator_domain_page_mbuf_size in the debugger for test.
I'll put it in at compile time but looking at the code that won't make a
difference.
Which memory allocation fails? Is it in the libbsd initialization or
afterwards?
