Hello,

 

We are using P2041 processor in our SBC. Our used part number is: P2041NXN7NNC which is security not present option. When I read PCI EXPRESS DEVICE ID REG at address 2h expected result is 0x0411.

 We have produced lots of boards and all returns 0x0411. But we have 2 board which had ID as 0x0410 in this register.

 

I have controlled markings of the processor ICs on these boards and they are P2041NXN7NNC. 

 

What can be the problem?

 

Thank you.
