Hi Narayan,

Thank you for reaching out on E2E.

TPS6521905 comes with all rails OFF and EN/PB/VSENSE configured in PB. Press down and release SW1 for 1sec and now you can communicate with the device.

Please refer to the NVM programming guide.

TPS65219 Non-Volatile Memory (NVM) Programming Guide

Please follow the 5 steps outlined on page 9 for NVM re-programming.
