Hi !

I'm using the TI EV2300 adapter to connect to my batteries (SMD connection).

To read the BQ2060 chip works fine. :D
To read the BQ2040 chip gives me read error. :shock:

I wonder if it can be a problem with the EV2300 and how to connect to read the 24C01 eeprom. I already order a CP2112 adapter from you, maybe it will fix my problems.

Is it possible with the CP2112 adapter read the eeprom and the BQ20xx chip one same time ?

Cheers
Andreas

To fix this battery you need to reset external EEPROM chip.
You need USB to GPIO adapter or LPT to SMBus adapter.
