I am trying to implementation the example "Matrix Multiply and ADD" using half float point. When all the code was executed in CPU, the result is right. When I switch "mmult" and "madd" from CPU to FPGA, although it can successfully generate the bit stream and image file, it still runs with error "ERROR: DMASIMPLE could not find physical address for buffer - make sure the buffer is allocated with sds_alloc". In my code, I do use "sds_alloc" to allocate the memory. Should I add some options to sds++?
