Hi,

I use the nRF52840 chip, which is designed as a module.

I use nRF9160 DK to burn the hex file.

1.And i can use nRF connect to read the ic of the module.

  But can not burn in .hex.(log is as follows)

2.I used nrfjprog to clear the flash and the results are as follows.

3.I used nrfjprog to burn hex, but it was not successful. The result is as follows.

What could be the problem?

Thanks.

Hi Terje,

I rechecked my hardware and found that 32.768KHz did not work, causing the programming to fail.

Thanks.
