Part Number: TPS40428

Tool/software: Linux

Hi,

In Our customised board we are using TPS40428 for Core voltage regulator. TPS40428 is connected to the processor through PMBus. Actually the Core voltage driven from TPS40428 is 1.005V But expected 1.025V. How to reconfigure the TPS40428 through PMBus in Linux or U-Boot.

Thanks in advance.

Regards,

Avinash N
