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:

root@hpvmfpga:[/home/aejjeh]: aocl install

2) Yes, jtagconfig passes

root@hpvmfpga:[/home/aejjeh]: jtagconfig
1) USB-BlasterII [2-1.7]                      
  02E660DD   10AX115H1(.|E2|ES)/10AX115H2/..
  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.
