  • [SOLVED] Flasher ATE - possible to write to registries without also rewriting the firmware?

    Hi,

    I'm using a Flasher ATE to program my J-Flash generated files. pex, dat, cfg files.

    #AUTO PATCH 13,100010EC,4:7014A777,100010F0,4:0101E968,100010F4,4:31330F42

    Something like this. It works fine. The thing is, during the test some new information is revealed, and I want to write that into another registry, without changing anything else, and without programming the firmware again. Speed is my concern.

    Is there a command for this?

    I'm picturing something like: #PATCH, which only does this.

    I know I can do this with nrfjprog, such as nrfjprog -f NRF52 --memwr 0x100010EC --val 0x7014A777, but that doesn't work with flasher ATE, does it?

  • Hello,

    the Flasher does not support "read-modify-write", therefore you'd need to create a second minimal data file which only contains the affected sector.
    This will be even faster than the "read-modify-write" procedure, because reading is not necessary.

    Best regards
    Arne
