Thanks for the input Chris!
I have no idea on rtems-libbsd. My RTEMS experience is limited for now. The
original idea was to have ethercat running on a LEON3 by Gaisler. Another
partner is developing the ethernet driver for that and I will have to
consult with him.
For now I read on how the build system works. Built the toolchain for
sparc/erc32 with the RSB on the 4.11 branch.
I agree that it is better to develop upstream and then build via the RSB
pulling the source from github or some other repo. That way you don't
replicate work and get all the patches. I will contact the SOEM maintainers
So I'll open a ticket and post any questions on the devel list.
