    Hello Darren,

    Thanks for your detailed post. Can you also share a screenshot of the Memory Options window (click "Memory option" to the left of "Results" section in MSP-GANG GUI)? I've attached a screenshot of mine.

    ERROR 41 indicates that the GANG flash write failed. Can you confirm that the "including locked INFO-A" option under "Information Memory Segments" was selected?

    Regards,

    James

    Make sure you're not exceeding the current supply limits of the MSP-GANG. Perhaps the supply voltage is dropping below the recommended levels for programming the device. Also, try slowing down the SBW speed. It sounds like it's a system level issue rather than an issue with MSP-GANG, since it's only happened on 7 devices. How many devices have been successfully programmed?

    Regards,
