DMA and Reed-Solomon Encoder IP blocks

[marioruiz]

Hi @Oumayma,

You have an open question about this already:

PYNQ-Z1 - IP or hierarchy not found in overlay-

You need to make sure that you are feeding enough data to the IP and the output buffer is big enough to receive the result. Please verify the IP documentation, https://www.xilinx.com/support/documentation/ip_documentation/rs_encoder/v9_0/pg025_rs_encoder.pdf I also suggest to run the IP test bench to understand better how it works.

As I mentioned in the other thread, I believe you are not defining your buffers appropriately. The RS encoder IP will add symbols to the input data, therefore the output buffer should be bigger than the input one.

How do you now that the RS encoder IP is not receiving data?

You can try to use an output buffer with shape=(64,) that may work, but it is just a hack.
