We're attempting to move from v1.1.0 to v1.2.0 of the NCS, in order to take advantage of some driver improvements (particularly DPD in the SPI NOR driver. When we migrate (using git checkout v1.2.0, then west update) our application no longer loads in the SES, saying "Invalid ELF file C:/blahblahblah/build_nrf52840_pca10056/mcuboot/zephyr/zephyr.hex".
I tried the samples (mcuboot/samples/helloworld in v1.1.0, bootloader/mcuboot/samples/helloworld in v1.2.0) without any modifications and get the same result. I'm using SES v4.2.0a, which is what was installed with v1.2.0 through the toolchain manager.
If I revert to v1.1.0, everything works fine.
Is there an SES setting that I need to change for v1.2.0? Since I'm getting the issue with untouched sample projects, I'm guessing it's something in my environment.
