Hi all,
I am trying to get MCUboot to work on my custom board with a SAMA5D2
(Arm V7A) and after a lot of battles am nearly there.
I can boot into MCUboot stored in flash, and I can also download/debug it.
MCUboot is happy enough with my firmware images to call my board's
"board_boot-image" function - but no SAMA5 boards in the repo have this
function for me to refer to.
Looking at, say, the function for the samv7 family I need a few lines
of assembly code - I think - to set the main and process stack pointers
and do the relevant reset. But I have no clue when it comes to assembler
unfortunately.
Any suggestions/ideas/whatever?
I'm thinking there might be some assembler related to the working
MCUboot binary that I can use as a basis, but where might it be hiding?
