Can anyone from Nordic comment on this?

The offending call is dfu_sd_image_swap() in bootloader_dfu_sd_update_continue(). dfu_sd_image_swap() call sd_mbr_command() with SD_MBR_COMMAND_COPY_SD, which returns 3.

Also seems to overflow into BANK 0 location. BANK 0 is correctly offset at 0x16000 and softdevice size was checked to be 0x15[something] so it shouldn't be overflowing.

Could this be a bug in the softdevice sd_mbr_command to copy the SD image?

I programmed the softdevice with --dfu flag as stated in the migratio notes (nrfjprog -e --programs <sd.hex> --dfu). In addition, the softdevice memory does get significantly changed and corrupts the original softdevice so something must be getting written.

I didn't use OTA for SD yet, but my blind shot is: check if enable softdevice protecion is checked in nrfstudio. i think it shouldnt be.
