AN881 reference design need to be upgraded for device 1SM21CH.

Hi Intel support,

I've tried it.

I modified the device and upgrade all IP.

The sof could be programmed to the FPGA successfully.

Besides, I install the Linux driver of this reference design.

However, it doesn't work.

Linux cannot recognize this FPGA board which has been connected to motherboard PCIe port.

We followed the steps on this user guide:

Linux didn't find the FPGA PCIe device when we entered the following command:

lspci -d 1172:000 -v | grep intel_fpga_pcie_drv

We have no idea what's wrong.

Perhaps Linux driver needs to be update for the new device?

Or the pin assignment of the reference design is wrong?

Or sof file has some problems?

Please help to check this sof and Linux driver on your board.

For your reference, our project files is as follows.

Thanks.
