Flashing issues

user113531

I use flash and erase button at Visual Studio Code but get warnings:
I use custom board, nrf sdk 1.9.1

Flashing build to 960168015
west flash -d c:\Users\maxim\Desktop\Projects\Git\vitals_app_v3_0\vitals\build --skip-rebuild -r nrfjprog --dev-id 960168015 --erase

-- west flash: using runner nrfjprog
-- runners.nrfjprog: mass erase requested

1. How to deal with warnings?

2. After erase and flash the device not reset 

3. Sometimes if i press Debug action i get "Error: GDB failed: Cannot access memory at address 0x85a61330 (from data-disassemble -s 0x85a61330 -e 0x85a61970 -- 5)" 

Thanks.

    Hello,

    These warnings are caused due to an update in nrfjprog (nRF Command Line Tools), which is used by West when flashing the devices. 

    1: Just be aware that the programming is not using the --verify flag. In general, that is not a problem. This would typically only be an issue when you are using nrfjprog --program, but you forget to erase the chip first (using --eraseall or --sectorerase).

    2: I have seen that from time to time. When you see this, what DK/sample are you using?

    3: Does that depend on what application you are trying to debug? Or is it regardless of the application? Does it happen if you use "nrfjprog --recover" on the device before programming and start a debug session?

    Best regards,

    Edvin

    Hi,
    I think all issues started after updating nRF Command Line Tools  from 10.15.4 to  10.16.0.

    1. Also if i press Erase and Flash to the board button i see same warnings.
    2. I use custom board nrf5340 that programed via nrf5340-DK
    3. No it is not  depend on what application, also after recover it can happen.
