Hi Joseph,

This is Oliver from the same company. We ordered the part from third party like digikey and we do not have a TI representative. I am wondering how we could get the device passcode in this case.

Regards,

Oliver

Hi Joseph,

I tried it on my side with TPS544C26EVM through I2C but I am getting a write error while writing to 0xB1.

By any chance that the pass code is different on the EVM?

Regards,

Oliver

Hello Cao,

You just need to ignore the error or NACK you are getting.

thanks!
