Part Number: TPS65982
I am having problems reading the TPS registers from the I2C interface. The TI part acks address 0x38, and other queries but when I go to read a register it returns byte count = 0. I have tried multiple different register reads and I always get the byte count =0. Does this indicate a corrupt PROM, or some other issue with the TPS. As I mentioned the TPS (slave) does ACK the address so it is not completely dead.

In reply to guy lemire:
Sorry for late reply. MODE register should say either BOOT (for example FW is not correct so x82 is stuck in BOOT) or APP (for example FW is correct and goodCRC happens etc.). If you are stuck in BOOT and read a register then it should have 0s. If the MODE register has 0s it is likely that the FW is incorrect or your I2C lines are not working properly.
thank you for your reply. Please close this case.
