Applications not running in non-secure

[pascal_dao]

Hello guys,

I am trying to run the mqtt_simple sample. I tried to do so on both nrf9160_pca10090ns and nrf9160_pca20035ns. The application builds fine for both boards but when I flash the program, nothing happens. I am expecting:

The MQTT simple sample started

to come through on the serial port but it never happens. I thought the issue was with the printk function so I tested a simple hello world and found out that when I flash programs for secure boards they run, but when I flash programs for non-secured boards (i.e. nrf9160_pca10090ns or nrf9160_pcs20035ns) they don't. The program seems to be flashed correctly but the application never starts or operates as expected.

Regards,

Try running nrfjprog --eraseall and see if that resolves your problem.

Best regards,

Simon

Now I can't flash the thingy91. It throws this error
