Dear Expert

Cross validation: Serial number 71901887LTF240901660558 can be burned normally/Serial number 71901887LTF24090160621 burned NG
1) After swapping two TM4C129ENCPDTI3R chips, the BMS board that could be programmed normally failed to be programmed, while the BMS board that could not be programmed normally could be programmed normally;
2) After replacing the BMS board that cannot be burned after swapping with a new TM4C129ENCPDTI3R chip, it can be burned normally.

    Hi Gabriel,

      Can you please elaborate what is wrong with the suspected chip?

      Is the suspected MCU a virgin/fresh device that has never been used before? Or it has been running on the field for some time. If it has been running on the field, how long was it on the field?

    Please provide problem description like:  you cannot connect to the device with the debugger or you cannot program the device. Or the device is loaded with the firmware but it does not run due to memory corruption or I/Os not toggling, etc? Please provide details.
