Hi, I tried the example design in UG20170 https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/avmm_stratix10_hard_ip+_ug.pdf.
I installed the driver and load the example design to the device successfully. However, when I use lspci to search the device, it cannot be discovered. And the test program didn't run as expected becauce the pcie device was not found.
The environment is Ubuntu20.4. The device is Stratix10 1SG280LN2F43E2VG.

Hi,
After you program the SOF to FPGA, did you reboot the host for it to perform the PCIe link training and enumeration?
