> 50000 peripheral memory accesses are needed [to initialize the hardware] Wow, that's a lot. If OP could upload somewhere the list of accesses together with a stack trace for each, I think we could crowd source a rewrite of each function - I'd be willing to bet the vast majority of those are repetitive patterns - ie. 'run this transmission test 1000 times while increasing the power levels each time until the received power = some set value'.
