In the new ALPHA Release 2016.01 filesytem, what is the "systemd way" of performing ifdown eth0 and ifup eth0?

Thanks for the reply.
1. Easier said than done ;)... The project is very "integrated". I have pared it down to something basic.

Those steps do appear correct.

the ARM code must load the DSP code.

I agree that since the debugger is looking for utl_halt.c something has gone wrong before main.

Good idea. Let us know if you find something that helps.

Thank you for the follow-up on this bug. I'm glad you got it working. I can't find any reference to case-sensitivity in the docs, so I create an internal issue for us to test this with our final Yocto release.
