nRF9160 DK recover

[LeoChen]

Hi,

I have two nRF9160 DK.

One of DK start freeze after programmed some applications.

I try to recovery it by "nrfjprog -e" but no help.

I try to install modem again but log said "ERROR: time out, no event received after 10 s".

How can I recover my nRF 91 DK?

Regards,

[John]

use Segger 4.16

Open SPM project remembering to ensure you use the secure option of the board not ns

Build Clean

Build Rebuild

When compiled:

Connect Jlink

Download zephyr.elf.

Open a command prompt and flash your modem software the way you had been doing it previously.
