Hi

we had also same issue PMIC TPS6521903 was booting Am62x processor.

after some nitration's in power cycle the output voltages of PMIC is 0 Volts.

can you please suggest any debug methods to see the faults / or configuration change  in NVM EEprom any more insights

    Hi,

    Thank You for using E2E. Could you share the schematic through private message? Additionally, we would like to see power-up scope captures showing the following signals (in the same order as they are listed):

    • VSYS
    • EN/PB/VSENSE
    • Buck2
    • LDO1
    • LDO3
    • Buck3
    • Buck1
    • LDO2
    • nRSTOUT

    Please combine as many signals as possible in the same scope captures.  

    Thanks,

    Brenda
