Hey guys, i kind of managed to get the riotboot tests to pass. Whenever i program via terminal (gcc-arm) i receive the error "[FAILED] You're not running riotboot". But when i program via the UniFlash tool, it works. Note, so far only "tests_riotboot-slot0-combined.bin" works. I assume its an offset issue as Gaëtan mentioned. Also, I used the cortexm_base.ld Linker Script.
