Hey Mario @marioruiz
I am not trying to allocate the PL-DDR, however, it seems to fall back on the contiguous memory allocator, nevertheless, xrt.xclAllocBO returns -1, which means it is trying to allocate buffers without success, It derives that the problem is also with the CMA .
I would try and update this dtbo, or even create a new one. The second question which raises is why the CMA fails. am I in the right direction?
Thanks, everyone.
