Trying to update the MAC address of an i210 using 'EepromAccessTool' v0.8.0

[Hugaerts]

Hi,

Since a while now, I'm trying to discover how and what to use to flash an empty i210 iNVM memory from an aarch64 system (imx8).
The chip is part of our board made in-house and the goal is simply to set the missing MAC Addresses and let the igb kernel module
recognize and manage that device (the device id is still 1531).

After many researches, NDA signed, mail exchanges, access to this portal, aso, aso... I received from your help the archive 'eepromaccesstool-0-7-7.zip' who is not working. However, reading this forum I found the version 0.8.0 and this one can be compiled and seems to discover the chips we have:

$ ./EepromAccessTool

2 1 0 0 I210 INVM+FLASH

Trying to dump the content of the NVM result in all the bytes at 0xFF:

$ ./EepromAccessTool -dump -nic=1

$ cat I210NIC1.otp
FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF
FFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFF
...

And trying to flash it with the provided 'I210_Invm_Copper_APM_v0.6.HEX' result in nothing at all:

$ ./EepromAccessTool -nic=1 -f=hex_files/I210_Invm_Copper_APM_v0.6.HEX

I've resetted the device many times... Tried all the provided hex images for the i210... Nothing works...

Thank's in advance for your help.
