Unittest stubs needed to be updated for the API change.
Although this API is private and internal to LoRaPHY, somehow it
appeared in the LoRaPHYStub. Updating it for consistency.
A new algorithm has been taken in use to calculate the receive window
length and the timing offset involved in opening of the said receive
window. This algorithm performs better than the stock algorthm and
consumes less power.
Previously we had been incrementing UL frame counter for a CONFIRMED
message only when the transmission was deemed successful i.e., we would
have received an ack before all the retries would have exhausted.
Now we have opted to increment the frame counter if all the retries are
exhausted considering the fact that we essentially treat the next
message after retry exhaustion as a new packet so we should also
increment the frame counter.
IAR 8 linker map puts C++14-style apostrophe digit separators in its
addresses, such as:
.data inited 0x2000'1ff0 0x4 mbed_rtx_idle.o [159]
Extend the regex pattern to allow this.
When using UARTSerial sending data over the uart follows the sequence
below:
<-TX done ISR runs and sets a software interrupt to pending
<-Software interrupt fires:
-disables TX done interrupt
-calls UARTSerial TX handler which sends bytes until the uart
buffer filled (writeable returns false). Sending a byte
re-enables the TX done interrupt continuing the cycle
Due to this sequence, if the UARTSerial TX handler does not send a byte
then the transmit state machine mentioned above will get stuck with
the TX done interrupt disabled. The events causing this failure:
<-TX done ISR runs and sets a software interrupt to pending
<-Software interrupt fires:
-disables TX done interrupt
-calls UARTSerial TX handler:
-checks writeable which is true and sends a byte
<- interrupted by a higher priority interrrupt
<- TX done ISR runs, setting software interrupt to
pending again
-checks writeable which is true and sends a second byte
-Software interrupt finishes
<-Software interrupt fires:
-disables TX done interrupt
-calls UARTSerial TX handler:
-checks writeable which is false and DOES NOT SEND A BYTE
-Software interrupt finishes, the TX interrupt is still disabled
*-Byte gets sent but TX done ISR does not fire
This patch prevents the TX lockup by removing the code in the
software interrupt which disables the TX done interrupt. Disabling the
TX done interrupt at this point is not necessary so this code is safe
to remove.
Update the LowPowerTickerWrapper class to handle rather than ignore
early low power ticker interrupts. This ensures that devices don't get
stuck in sleep due to a ignored early low power ticker interrupt.
Update the padding sequence so that the gaps
are padded after all the regions are merged.
This avoids overwriting active regions and
serializes the process.
NRF Softdevice hex file can be in chunks.
Make sure we account for the space where the bootloader resides
by including all the chunks within the end of rom marker. This will
clearly mark out the initial bootloader region.
Reduce the default size of `MBEDTLS_MPI_MAX_SIZE` to 512 bytes,
as the default 1024 consumes much stack, and supporting RSA 4096 bit
may suffice at the moment.
With support for checking H/W UART initialized or not, we can simplify stdio management:
1. When serial_init(&stdio_uart) calls in, just set the 'stdio_uart_inited' flag.
2. When serial_free(&stdio_uart) calls in, just clear the 'stdio_uart_inited' flag.
Except above, we needn't make special handling with 'stdio_uart'.
