  • [SOLVED] Preservation a flash memory area when programming MCU in J-Flash

    Hi.
    It is necessary to program the GD32F330F8P6 microcontroller with the preservation of the memory area 0x800FC00 - 0x800FFFF (the last sector), in which the calibration coefficients are located. Please tell me how this can be done in J-Flash?

  • Create a batch file or similar, that calls J-Flash 2 times:
    1) Read back of calibration data + save as hex file

    2) Open file to program, pass „merge“ command and specify 2nd file (the calibration data hex file), followed by the „auto“ command that does erase + program + verify
    Please read the forum rules before posting.
