The boot pin has been confirmed to be uart1. Please help her.

    WIthout the UART Host tool,  have they tried to see if the on a serial terminal if the BOOTME is received correctly ? Have they used Secure AIs gen tools to generate the output binary.  Did they test the board with non-secure device before trying this test with the secure device. We are trying to understand if this is a hardware issue or software issue.

    We have binary that we used to test JTAG unlock on Secure devices, that I have attached here. can you try to load this on the custom platform and test it the devices will boot and unlock JTAG

    I will send you some additional material for secure devices offline to forward to this customer.

    Regards,
