I210 NVM Programming base on ARM processor (about eepromaccesstool-0.8.0)

- We designed H/W which Raspberrypi compute module + PCIe switch + I210AS(2ea) + I210AT(2ea) + NVM(SST25VF080B : 8MBit)

pi@raspberrypi:~/New_driver/eepromaccesstool-0.8.0 $ uname -a

Linux raspberrypi 5.10.52-v7l+ #1441 SMP Tue Aug 3 18:11:56 BST 2021 armv7l GNU/Linux

- I mounted NVM(already programmed) on my board. It was good operating like ping test, internet access.

pi@raspberrypi:~/New_driver/eepromaccesstool-0.8.0 $ lspci -ntv

-[0000:00]---00.0-[01-06]----00.0-[02-06]--+-01.0-[03]----00.0 8086:1536

+-03.0-[04]----00.0 8086:1536

+-05.0-[05]----00.0 8086:1533

\-07.0-[06]----00.0 8086:1533

1) And I try to get NVM information. But the information is something wrong.

NCI=1&4 was not detect FLASH.

pi@raspberrypi:~/New_driver/eepromaccesstool-0.8.0 $ sudo ./EepromAccessTool

Intel(R) EEPROM Access Tool NVM/OTP Programming Example Tool Version 0.8.0

NIC BUS DEV FUN Silicon Memory Type Present

=== === === === ===== ======================

1 3 0 0 I210 INVM

2 4 0 0 I210 INVM+FLASH

3 5 0 0 I210 INVM+FLASH

4 6 0 0 I210 INVM

2) I expected that if remove all NVM, “MEMORY Type Present” will be displayed “INVM” only.

but the result is strange. And more strange point is NIC number was changed. It is not fixed NIC number.

=== === === === ===== ======================

1 3 0 0 I210 INVM

2 4 0 0 I210 INVM+FLASH

3 5 0 0 I210 INVM

4 6 0 0 I210 INVM

“INVM+FLASH” displayed on the secondary device among recognized devices.

(more detail contents include attached file).

3) I mounted blank NVM on my board.

pi@raspberrypi:~ $ lspci -ntv
-[0000:00]---00.0-[01-06]----00.0-[02-06]--+-01.0-[03]----00.0 8086:1531
+-03.0-[04]----00.0 8086:1531
+-05.0-[05]----00.0 8086:1531
\-07.0-[06]----00.0 8086:1531

But, result was same like when NVM removed all.

2 4 0 0 I210 INVM+FLASH

3 5 0 0 I210 INVM

4 6 0 0 I210 INVM

4) Nevertheless, I was suspicious of the hardware part, so I checked the signal line of the NVM (Chiselect). NVM was programmed NVM. (more detail contents include attached file).

- When board power-up and power-down, signal operating was fine.

- When I try to access NVM through eeprom access tool-0.8.0, all signal line was not operated at all.

- I did not found out H/W issue not yet.

- I checked FAQ document 2.23, 2.25. It was not helpful for me.

- please advice for me hint /documents / anything.

- Please send to us eepromARMtool (old verstion ??) . I want to test old tool.
