03:08 PM Software Development: RE: FPGA (FIFO) -> DSP (DMA) transfer problem
The fpga guys can step in if I've missed something but it looks to me like your missing cache invalidate calls. If t... Jonathan Cormier
08:57 AM Software Development: FPGA (FIFO) -> DSP (DMA) transfer problem
hello.
I am posting because I have a question related to DMA.
The last CCS issue was not resolved, so I am loading ...
