PKTEND usage: Problem about short packet
I have a problem about PKTEND# usage with short packet.
I set DMA buffer size as 1024bytes on device side, and set "bytes to transfer" as 2048 on Cypress Control Center. When I wants to send a short packet, for example, 1020 bytes, I assert pktend# with last word, and this is ok.
But when I wants to send 1024 bytes and assert pktend# with last word, I can not read data from Control Center. Should I append a ZLP on this situation? Why does not FX3 consider the pktend# valid ?
