I’m really enjoying the posts, please do keep them coming.
There was one thing I was curious about in the assembly code snippet:
static void start_app(uint32_t pc, uint32_t sp) attribute((naked)) {
__asm(" \n
msr msp, r1 /* load r1 into MSP /\n
bx r0 / branch to the address at r0 */\n
");
}
Is this deterministic? Will the pc variable always end up in r0, and sp in r1?
Is there a way of doing this by using the symbolic names?
