I'm trying to make a version of a HAL timer that uses async
to sleep. I use a priority queue and it all works great in debug, but when I compile in release I get a hard fault. The assembly instruction that causes it is
10a8: strd r5, r5, [r4, #72]
which is apparently a double word store. Can anyone help me debug this - I just don't know much about ARM assembly.
Whole code available on github. It's a firmware for the pinetime smartwatch, but at the moment I'm playing with sleeping the hf clock during downtime. I'm compiling it for thumbv7em-none-eabihf
using cargo-embed
.
