Description
Endless loop in runtime_nrf.go: sleepTicks() function can happen for parameter d >= 0x800000 (>= 256 seconds for 32768Hz ticks) because & 0x7fffff operation will return 0 for second and following loop runs and d variable remains unchanged:
Current version:
func sleepTicks(d timeUnit) {
for d != 0 {
ticks := uint32(d) & 0x7fffff // 23 bits (to be on the safe side)
rtc_sleep(ticks)
d -= timeUnit(ticks)
}
}
Fixed version:
func sleepTicks(d timeUnit) {
for d != 0 {
ticks := uint32(d)
if ticks > 0x7fffff { // 23 bits (to be on the safe side)
ticks = 0x7fffff
}
rtc_sleep(ticks)
d -= timeUnit(ticks)
}
}
