Hello,
I am trying to program the application into the CortexM33.
I am using the lte_cloud_demo_v0.3.5 , compiled under Keil.
using nrfjprog:
\DemoPack1_EU-1.4\Firmware\Application\lte_cloud_demo_v0.3.5\examples\demopack\pca10074\blank\arm5_no_packs\_build>nrfjprog -f nrf91 --program nrf9120_xxaa.hex --sectorerase

Applying system reset.
Checking that the area to write is not protected.
Programing device.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
Also, using Keil programmer, or J-link flash lite, it is the same.
I managed to connect to SWD still (using j-link commander for instance),
