Download eeprom for mt7688

[Microdrive]

Please help me!

I'm using the mt7628-for-mt7628-linux-4.4.61.ko driver. Chip mt7688. My driver uses the default settings for eeprom and does not load the MAC address and other parameters.

When the command is executed

ifconfig ra0 up

Outputs (driver in debug mode):

It looks like the file mt7620.eeprom.bin is ignored! The driver loads the eeprom from the "factory" section.

The analysis of the source code showed: 1) The driver loads the eeprom into FLASH mode ([3909.396916] NVM is FLASH mode) 2) The validFlashEepromID (pAd) function reads the first 2 bytes of the "factory" section and if they equal 0x7628 returns "true".But my validFlashEepromID returns false !!! Why??? My "factory" section looks like this:

3) The eeprom buffer is loaded from the MT7628_EEPROM_20140317.bin file. MT7628_EEPROM_20140317.bin - default settings.

Nossiac, please see the source code. What could be the problem?

Thank you!

Did you solve the problem? I also have this problem...

Mac is at the wrong address. Use latest openwrt i think they solved that.
