    Hi,

    I can see there is some ESM fault, BSS has raised in your case.

    Those payload (8 bytes) are pointed to two uint32 variables.

    Could you let me know what is value of 

    rlBssEsmFault_t -> esmGrp2Err

    i.e. payload[4:7] are stored as 0x00000020 or 0x20000000 ?

    With this clarity only we can find the cause of ESm fault.

    rlUInt32_t esmGrp2Err;

    And apart from that, what is the scenario which has caused this ESM fault??

    Regards,

    Jitendra

    Hi,

    Thanks for your reply, the value of rlBssEsmFault_t -> esmGrp2Err is 0x00000020.

    Hi Edward,

    As you can map that bit to ESM fault error

    bit: 5 ATCM DB error.

    Could you explain the scenario under which you are  observing this ESM fault? Do you enable any Monitor feature of device?

    Regards,

    Jitendra
