C API drivers for PYNQ FPGA board

pynq_api's Issues

ACP port

Hi Mesham!

I want to accelerate a library and compile it on the pynq board (on top of linux). I think that your library might help me with that, however, I want to use the cache coherence port (ACP) so that all my memory accesses go through the PS cache hierarchy. Basically, my PL does not use DMA at all. I was curios if your API allows for this? If so, what function should be used?

PYNQ_allocatedSharedMemory on ZCU102（ultrascale + MPSoc）doesn't work as expected

I use PYNQ_allocatedSharedMemory to allocate space on ZCU102(PYNQ 3.0), It returns a non null pointer(state->pointer is not null). However, when I use "malloc_usable_size" to view the size of the space pointed by the pointer, the result is zero, which lead to "core dump(bus error )" in “memcpy” function. How to solve this problem？
