Hi I agree that even driver is not install successful, it still able to detect by the host as unknown device. So now we can rule out the driver issue.

Suggestion:

  1. is it possible to borrow the BHU variant board from field team and test it with original AN881 design using the same linux host? The reason is to rule out is issue is due to variant or the particular host actually unable to detect any FPGA gen3 card.
  2. What is the slot PCIe capability? Have you tried go into the bios and fix the PCIe slot setting to Gen3x16? In some host, it will create some problem to detect when the setting is AUTO.

Hi,

​

Another question, is the pin assignment of 1SM21BHU the same with 1SM21CHU device?

​Currently all the user guides and documents are based on 1SM21BHU.

We don't know whether there is difference except HBM2 size.
