Hi,

I have question regarding ICC.

I want to have a function or in this case a bare metel task running on core B and have core A  running uClinux.

I want to do a function call and pass arguments from Core A to Core B via ICC, I already have it so I can pass arguments, in this case a structure. This structure contains data pointers to large buffers in external L3 memory being access by Core A. So in this case is it possible for Core B to share L3 Ram with core A?

Thanks,

Blair

Yes, ICC is designed for this kind of use case.

See example code under lib/libmcapi/libmcapi-2.0/tests/pkt3.c and user/blkfin-app/icc-utils/example/task/mcapi_pkt3.c
