Hi,

​

We changed Quartus version from v19.1 to v19.3, and now Linux could recognize the board!

All ​PCIe reference designs includes AN881 could be detected by "lspci" command.

​

However, there is still something wrong.

We use AN881 driver, it could read configuration space, but couldn't access HBM2/DDR4.

​

​Besides, the AN881 document doesn't describe how to set DMA clearly.

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an881.pdf​

What's the flow to use above gui?​

​

Thanks.

    Hi

    ​

    Only "4. read configuration space" works, we could read vendor ID.

    "0. Link Test​" we got 100 R/W/mismatch errors.

    "5. Change BAR" we got "Could not change BAR"​

    Do you have any suggestion?
