Flashing new image erases user storage area.

[Venka Gade]

I am using nvs_init(), nvs_read(), nvs_write() calls to store and retrieve user data. Everytime I flash a new image I use the following commands:

# nrfjprog -e -f nRF91

# west flash

I have to specify -e -f flags. If I omit those flags, the unit will not boot and gets stuck at the following logs

SPM: NS image at 0xc000

SPM: NS MSP at 0x2002c120

SPM: NS reset vector at 0x13b2d

SPM: prepare to jump to Non-Secure image

Try updating to the newest nrfjprog and check if that resolves your issues.

What version do you recommend? 

I am using the latest from nordic site:

nrfjprog version: 10.3.0

JLinkARM.dll version: 6.44e

[Simon]

The latest version is 10.4.1, try updating to that and see if your problem goes away (direct download link).

Best regards,

Simon
