Hi,

 

May I know what OS you are using? Could you please provide the output of sudo lspci –s $bdf -vvv (e.g sudo lspci -s 81:00.0 -vvv)?

Hi,

Could you please read the device control register by using command below?

sudo setpci -d 8086:094C 0x78.L

This is to check if bit 7:5 is set to 001b for 256 bytes max payload size? If not, please configure the bit 7:5 as 001b, and then run the test again.

For example:

sudo setpci -d 8086:094C 0x78.L=0009203e (please change bit 7:5 as 001, the rest remain the same as what you read out)

If above do not help, please also read the uncorrectable & correctable status register to further understanding the problem.

 

sudo setpci -d 8086:094C 0x110.L

sudo setpci -d 8086:094C 0x104.L

​Just to clarify, for Arria 10 device, the Device control register is at 0x88 (0x78 is for Stratix 10 device). Therefore, the command should be sudo setpci -d 8086:094C 0x88.L

f1becd33b87b8eecf6d5b26c278ba42.png​I have run the commandsudo setpci -d 8086:094C 0x88.L,the value is 0009283f while 7:5bit is 001b. And what can I do next to solve the errors.

​Could you please share the output of correctable/uncorrectable status "before" and "after" run the fpgabist nlb_mode_3.gbs test? How many boards encounter this error? Do you try to program the flash again, and re-install the DCP 1_2 stack?

 

Below is the command:

sudo setpci -d 8086:094C 0x110.L

sudo setpci -d 8086:094C 0x104.L
