Hi,
I have searched the forum but haven't been able to find a solution that works for me. But I am using a nRF9160 on a custom board and am trying to use SDK 2.5.0 with MCUBoot and TFM for secure boot. The application is a simple one to start with, I just want to print some statements using printk to get some information about the modem and then turn the modem on to connect to the network. I have the application building and can flash the nRF9160 using a jlink, but whenever I try to run the program, MCUBoot gives me an error saying that the primary slot is not valid. I have attached my configurations below as well as the static partitions I'm attempting to use. Can you please help?
Terminal Output from device:
*** Booting nRF Connect SDK v2.5.0 *** I: Starting bootloader I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3 I: Secondary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3 I: Boot source: none I: Image index: 0, Swap type: none E: Image in the primary slot is not valid! E: Unable to find bootable image
