Arria 10 GX FPGA Dev Kit OpenCL and PCIe drivers/runtime stopped working

Hi Mylee

Here are my answers to your question:

1) I think so, here is the output:

2) Yes, jtagconfig passes

root@hpvmfpga:[/home/aejjeh]: jtagconfig
1) USB-BlasterII [2-1.7]

  020A40DD   5M(1270ZF324|2210Z)/EPM2210

3) I cannot run aocl program because aocl does not detect the device to start with

4) Not sure what you mean here, I reboot the machine manually when I am trying to initialize the board. I have a script that I use to initialize the board based on the AN 807 Intel document: https://www.intel.com/content/www/us/en/programmable/documentation/tgy1490191698959.html#wmh1490212984610

Basically, I set the jtag speed to 6M, then I run the following two commands:

quartus_pgm -c 1 -m JTAG -o "p;max5_150.pof@2"
        quartus_pgm -c 1 -m JTAG -o "p;top.sof"

After that I do a soft reboot. When the reboot is done, I used to run aocl install and then the board would work.

5) The board is inside the PC chassis. I cannot see the LCD display while the board is connected to PCIe.

Hi Mylee

The usb cable is working, jtag-config detects the board and works. I can program the board with no problem. Also, as I mentioned, the board was working previously, and I have previously configured all switches and jumpers according to an807. I confirmed that there was a kernel update prior to the board stopping to work.

Hi Mylee

To answer your first question, no we do not have another Dev Board to try out.

As for the linux kernel update, yes I performed "aocl install" AFTER the linux kernel got updated. I have posted the output of "aocl install" in one of my previous messages. The device is definitely properly installed, I have not removed it.
