Nick,
I have implemented user-defined host calls. Let me look into this to see what is going on. I will follow up.

Thanks dar,

I've updated my git repository () with the call back code in it.

Nick,
Just an update. The documentation is unclear, but the bigger issue is that when I ported to the 2016 parallella image, symbol changes for this feature were overlooked. The changes from 2015 to 2016 images included completely changing the ABI symbol naming conventions and required going through and adjusting in many places. This got overlooked. I will update when I get this resolved and my test code is able to link.

Hi Davi,

Have you had a chance to update the code to reflect the changes?

I'm still working on the idea that the ARM cores and the epiphany cores can work together in parallel so that the results from the epiphany processing can be collated on the host cores while the epiphany cores are working on the next chunk of data. I was hoping to use host calls to kick off a process on the ARM to retrieve the data from shared memory.

If there is another way of doing this I'd be glad for some pointers.
