Implement the following:
KVStore base class
TDBStore class
FileSystemStore class
SecureStore class
Global APIs
Configuration framework
Design documentation
The new PSA-aware Mbed TLS importer script calls `config.pl` on the
Mbed TLS config.h to set the PSA configuration option
MBEDTLS_PSA_CRYPTO_STORAGE_C which isn't documented in config.h.
config.pl therefore fails, and so does the importer.
This commit fixes this by calling `config.pl` with the `--force`
option which amends the given `config.h` by a `#define` for the
requested option if the option isn't present in the file.
- Fix handling of duplicate blockwise ACK's
CoAP data buffer was not added into duplication info store when creating response for blockwise request.
This leads to case where whole bootstrap flow just timeouts if received any duplicate messages during blockwise operation.
Fixes error: IOTCLT-3188 - UDP connection fails for lost ACK sending
- Remove error trace when building reset message without options
This makes it possible to build the reset message without allocating option or getting error message.
When initializing serial disable all interrupts as some of these may
have been enabled by a bootloader. This ensures that the NRF52
serial driver remains compatible with any bootloader version.
Make the following enhancement:
-Support serial port use without flow control
-Prevent dropped bytes by updating flow control handling
-Remove dead code
Serial port use without flow control:
In the prior implementation there was a window of time between
reloading DMA buffers after a timeout where bytes could be dropped.
This is because the uart needed to be turned off in order to flush the
bytes in the DMA buffer.
This change configures the DMA buffer to only receive one byte at a
time so there is no need to disable the uart to flush it. After each
byte is received the DMA transfer will be over so the transfer will
never be partially complete and need flushing. Since the uart is
always on it is safe to use it even without flow control.
Prevent dropped bytes by updating flow control handling:
To prevent dropped bytes due to high latency the flow control handling
of the RTS line was configured to be asserted automatically by
hardware after each byte. Once the CPU has read the byte and setup
the next receive buffer the RTS line is deasserted to the transfer can
continue. This ensure that when flow control is enabled data won't be
lost due to interrupt latency.
Remove dead code:
With the above changes there is a lot of dead code, such as the timer
handling code. This patch removes the code that is no longer used.
### Description
Arm compiler 5 builds with "short" enums and "short" wchars. This means
that C/C++ enums will be packed into the smallest power of 2 number of
bytes by the compiler and the `wchar_t` is 2 bytes. Arm compiler 6
defaults to packing enums into 4 bytes and `wchar_t` is 4 bytes.
Further, Arm Compiler 5's `-O0` (no optimizations) bulids will actually
do some amount of optimizing, similar to Arm Compiler 6's `-O1`. I have
switched the debug profile to `-O1` for maximum compatibility with our
prior behavior.
NOTE: "Compatibilize" is a word
