DMA Loopback test fails on Acorn CLE-101 #86

Closed MattEttus closed 2 years ago

MattEttus commented 2 years ago

Built using: $ ./sqrl_acorn.py --variant cle-101 --with-pcie --uart-name crossover --build

With Vivado 2021.2

$ ./litepcie_util dma_test Unable to find DMA RX_DELAY (min errors: 2048/2048), exiting.

litepcie_util scratch register test and info both work.

@MattEttus: I've been able to reproduce on an Acorn CLE101 and no longer see it with https://github.com/enjoy-digital/litepcie/commit/1a0857323b51780d6d45f4e1e3865d42b1b98299 and https://github.com/enjoy-digital/litepcie/commit/d3af0fcfd805d834b19ed287ecb7b4c689f612be.
