How to use MT7612E with build-in eFuse?

[wwng2333]

Sorry for my bad English.
I have a MT7612E MiniPCIe card, with PA/LNA.But works badly on openwrt.
I contacted the 7612E wireless card manufacturer, the factory has written the data to the on-chip efuse, this area is one-time, cannot be erased after the write.
So I want to know how to make the driver use build-in efuse instead of reading EEPROM.

by dropping eeprom entry from dts. but you can also cat debug contents of efuse data and compare with eeprom data

Got it,by the way, can you tell me how to get and export data from eFuse?

[psyborg55]

@wwng2333 , did you get your MT7612E to use the build-in efuse?
Would you mind sharing details on how to do it?

Is there any one could help to explain below.
In mt76x02_eeprom.h

enum mt76x02_eeprom_modes {
MT_EE_READ,
MT_EE_PHYSICAL_READ,
};

what different is between MT_EE_READ and MT_EE_PHYSICAL_READ?

Thanks.
