Over the past week, some of our users have encountered a known error code with an unknown error code 512. This issue occurs for a number of reasons. Let’s discuss this now.
I am testing xdma transaction with AR65444 driver. The design is a sample design for the PCI DMA Subsystem for Express v4.0 IP Addresses (page 195).
but as soon as I run the run_test.sh test, I actually get an unknown 512 error. How do I solve this problem?
