word alignment errors during init of epiphany about pal HOT 3 CLOSED

Ok so drilling down a bit into this. the tests try to map memory for status and results and this api call is failing.. I am guessing that the changes to the kernel make p_map unsupported on Epiphany so I am now looking for an alternative way to map memory with something like e_shm_alloc() perhaps the pal equivalent has not yet been implemented?

reg_write(core, i << 2, MMR_R0 + (i << 2));

Thank you, don't know what I was thinking there, I think it should be this though ?

reg_write(core, MMR_R0, (i << 2));

right now the posix host --> epiphany device code only works with the simulator
I'll fix the native device code as soon as I can but it won't be for another week or two.
Patches always welcome of course ;)

If you want to hack on it you'll likely find all bugs in src/base/devices/posix/epiphany/device.c

It might be enough to fix dev_map(), dev_map_raw(), and provide a mem_ops structure,
see simulator.c for how it's implemented there.

Cheers,
Ola

@olajep I have created a pull request to fix this and make my version of the epiphany test work. I will do a bit more later and modify runtest.epiphany.c. My test version worked with this code and got a response from the epiphany core so I think that the changes are good.
