Issue with updating ARIA 10 PCIe core to 20_1_1

Hi Wincent.

The failure varies build to build. I am looking at the most obvious error which is the FPGA enumerates okay in the PCIe but all host to FPGA accesses return 0xffffffff. What I just noticed in the lab is the LEDs seem to indicate a good portion of the FPGA is not working. It programmed and loaded okay but more than just PCIe appears to be broken.

Other failures include lockups, DMA (device to host failures), and host to FPGA access returning wrong data (other than 0xffffffff).

I performed a DSE run and out of 11 builds:

3 - work okay

4 - experience the 0xfffffff problem

4 - have other issues as listed above.

I did a DSE run on our other design which is Gen 3 x 8 and targets the exact same board. All 11 builds work fine.

I will continue to look at one of failing builds.

Thanks,

Mike
