  • [SOLVED] extend flash area

    Hello,
    I need to flash a certificate(binary file) onto my MCU (MAX32651) to a one time programmable area in the flash.

    My Flash base address is 0x10000000 and its size is 3072 KB and my certificate should be written to offset 0x801000( which is much larger then 3072K). What do I need to do to be able to flash the certificate ?



    # I am able to accomplish all of this with gdb+openocd+olimex(debugger), but I am trying to move my setup to SEGGER products.


    Thanks!

  • A little bit more details -

    When I try to flash the certificate with JFlash with this command :

    Source Code

    1. JFlash.exe -min -jflashlog"C:\Users\david\workspace\firmware"/build/jflash.log -openprj"C:\Users\david\workspace\firmware"/tools/jlink/flash_crk.jflash -open"C:\Users\david\workspace\firmware"/maxim_test_crk.bin,0x10801000 -program -exit

    I get :

  • Hi,

    Without checking the manual, not sure what this area is. What I can say is that it is currently not supported.
    While SEGGER may add support for it in a future version, there are no immediate plans yet.
    You can always add new flash banks on your own via open flash loader:
