24d6b9ed6c Build stm32 and stm32-examples in test script. 
Panic handler was missing, I had to add exaple_common.rs like in the nrf examples.

93780fa31d uarte: Wait for the peripheral to be disabled 
Prevents a panic in the case of:
1. Abort a receive future
2. Free Uarte::free()
3. Uarte::new()
->  panicked at 'assertion failed: uarte.enable.read().enable().is_disabled()'

9b1f7b8a17 uarte: Enable peripheral with first poll 
This fixes a lockup when a future is dropped before it was polled.

85ec9dd16f uarte: Be on safe side with potentially racy code 
The PS does not specify how many cycles it takes for a STARTXX task to
generate a XXSTARTED event. I think it is instantaneous but let’s be on
the safe side for the following sequence:
1. poll() starttx
2. drop() txstarted not yet set, but future gets dropped
3. txstarted set by hardware, peripheral enabled after it was dropped

a3b3305b8e uarte: Only stop TX forcefully when a transmissions is running 
This comes with insignificant power consumption improvements but makes
the code of the RX and TX case symmetric.
 2021-01-04 22:55:40 +01:00
Timo Kröger
a7c03e4cb6 uarte: Only stop RX forcefully when a reception is running 
The STOPRX task always triggers a timeout of ~55bit times until the
RXTO event is generated. Before we disabled the receiver only after
the timeout.
With this change the receiver is stopped right after reception has ended
because the DMA buffer is full.
For forced RX aborts like `stop()` or on drop still need to wait for the
RXTO event before disabling the receiver.

Timo Kröger
9f28c7ab8d uarte: Do not spin when stopping a receive future 
Spinning on drop() is still required when the future has not been
stopped so that DMA finishes before the buffer is released.
