![]() It's true that booting normally doesn't take long enough for the register to roll (which actually happens in a little over an hour, not just a few seconds). However, the counter starts at power-on, and if the board is held in reset to be booted over USB, one actually risks hitting wrap-around during boot, which can both result in too short delays (if the "st += delay" calculation makes st small) and theoretically also unbound delays (if st ends up being UINT_MAX and one just misses sampling digctl_microseconds at that point). It doesn't take more code to DTRT, and once bitten, twice shy. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk> |
