Hi, all.
I am studying Beaglebone black, and now I am facing with internal EEPROM problem.
I searched couple of days, but no idea yet.
How can I read and write to the internal EEPROM of beaglebone black.
Best regards.

What problem are you facing?

The eeprom is write protected, other then that it's accessible thru
the standard i2c/eeprom interfaces..

Thanks, and sorry to late reply.
I am going to use internal EEPROM of beaglebone black.
I should write some data to it. I can read data from the internal EEPROM, but writing is not.
I grounded TP4 pin for EEPROM write. But it doesn’t work.
I maybe new to beaglebone.
Beaglebone SRM document says we can use internal EEPROM for personal purpose.
