Thanks for the advice guys, but I'm still struggling to get the cc2538dk to pass the riotboot tests. To: Francisco Acosta
I provided the length and start variables to link the slots. I used the cc2538sf53.ld Linker Script. I was not sure how to get the offset required, so i used 255 as the offset, this value made the slot0.riot.bin file = 512KB. I assume this correct because whenever you compile an example (not with riotboot), it generates a .bin file with this size. Any ideas on what i could be doing wrong? With thanks!
