Problem with nrfjprog

[Omar]

  Hi 

The Zephyr mesh_demo project has been built correctly but I'm facing a problem when I flash it

C:\Users\OMAR\zephyrproject\zephyr\samples\bluetooth\mesh_demo> west flash

-- west flash: rebuilding
ninja: no work to do.
-- west flash: using runner nrfjprog
Using board 682695511

Hi,

Are you programming a Nordic Development kit, or a custom board? Also, have you tried other examples to see if the issue might be limited to this particular example?

You may also want to try to run 'nrfjprog --recover && nrfjprog --readregs'. If that doesn't work either, then it's likely a communication problem with the chip, which could be caused by wrong voltage levels or a bad connection.

yes I'm programming nr52832 DK and nRF 52840 DK

and the problem happens with the other example also

I have tried nrfjprog --recover and it working now 

thank you
