The reallocation trigger for unpacking star args with unknown length did not take into account the number of fixed args remaining. So it was possible that the unpacked iterators could take up exactly the memory allocated then nothing would be left for fixed args after the star args. This causes a segfault crash. This is fixed by taking into account the remaining number of fixed args in the check to decide whether to realloc yet or not. Signed-off-by: David Lechner <david@pybricks.com>
In-the-field use of these FUS/WS firmware update scripts has exposed some weak points, causing corrupted FUS/WS firmware to be flashed to the unit. The problems are mostly caused with the ST GUI application, but sometimes from un-recognised failures during bin file transfer to the WB55 prior to running the rfcore_firmware.py script. Other failures were caused by incorrect load addresses being used, again both from user error copying the address from the HTML release notes to the GUI tool, but also from similarly not updating the address correctly in rfcore_firmware.py To guard against these errors and make it easier to prepare different versions, this commit adds a few features to the rfcore firmware update tools: - When creating the bin file, automatically parse the release note in the folder to get the correct address. - Add a footer to the bin file containing the name, version, CRC, address etc. - Before flashing rfcore, check if the same version is already installed. - Verify the CRC and obfuscation key before flashing bin. - Log the name and version of file being flashed.
