  • [SOLVED] erasing and loadbin

    Hello
    I have observed from log files that when I execute from script file the loadbin command, Jlink also does a checkup if the binfile is already in MCU flash memory; then it is erasing it, andthen it programs the bin file; after that it checks again if the bin file is in the MCU memory.

    Right now I am erasing the chip and then use the loadbin command.

    It is safe to skip the erase step?
    Is the erasing embbeded into loadbin command equivalent to erase command ?

  • Erase, without any further parameters, will erase all flalsh banks known to J-Link for the selected MCU.
    This means, for a MCU with 2 MB flash, it will erase 2 MB.

    Loadbin erases the affected ranges. Meaning if your bin file is 512 KB in size, only 512 KB (rounded up to complete sectors) will be erased + programmed.

    So if you do not care about the other ranges, you may skip the extra erase step.
