Software update: Betaflight 3.5.5




Drivers or flightplanes use flight controller software. Open source examples include MultiWii, Baseflight, Cleanflight and Betaflight . The latter includes support for dshot, multishot and onshot engine protocols, STM32, F7, F4, F3 and F1 processors, telemetry protocols, and OLED displays. Betaflight 3.5.5 has appeared with the following announcement and list of changes:

Maintenance Release

Please read the Betaflight 3.5 Release Notes. This release contains bugfixes and target changes only. For a full list of new features see 3.5.0. We have tried to make this release as bug free as possible. If you still find a bug, please report it back to us by opening an issue here. We also have a Facebook Group: If you want to talk about Betaflight, ask configuration questions, or just hang out with fellow pilots, you can do this here.

Important information when upgrading from an earlier version of 3.5
a number of users reported issues with the firmware hanging during a diff or dump. The root cause of this was identified as a bug in the MSP protocol causing corrupted configurations. This was fixed in 3.5.1. If you are using 3.5.0, it is recommended that you upgrade at least 3.5.1, to eliminate the risk of experiencing lockups (# 6696);
unfortunatly, bugfixes in the flight controller core functionality have led to an increase in the firmware size, causing it to overflow the available space on a number of F3 based flight controllers. As a result, some features have been removed from a number of F3 based flight controllers in order to make the firmware fit into flash. The following targets are affected: AIORACERF3, FRSKYF3, IMPULSERCF3, RACEBASE, RG_SSD_F3, RMDO, SPRACINGF3, SPRACINGF3MINI, SPRACINGF3NEO, STM32F3DISCOVERY, and ZCOREF3 (# 6815, # 6887, # 6994, # 7239, # 7241, # 7362).
Safety Improvements:
Made the most important OSD warning show with highest priority (# 7276);
Fixed the behavior of the ‘car’ failsafe setting for throttle when 3D is used (# 7352).
Fixed OSD temperature display for negative temperatures (# 6973);
Fixed switching or PID profiles with stick commands (# 7218);
Fixed potential error when printing configurations in CLI (# 7232);
Added resetting of the GPS rescue maximum altitude and distance on arming (# 7244);
Fixed a problem with the sanity checks in GPS rescue causing sporadic disarms (# 7254, # 7265));
Fixed on-board flash MSC emulation for MacOS on F7 (# 7266);
Fixed sporadic twitching in FrSky X SPI when sending failsafe values ​​from the TX side (# 7345);
Hide stale altitude and vario in OSD when GPS fix is ​​lost (# 7368);
Check that a MSC capable storage device is selected for blackbox before rebooting into MSC emulation mode from CLI (# 7380);
Fixed a boot loop if rebooting into MSC is not ready (# 7382).
Target Updates:
Fixed the pin assignment for the softserial ‘TLM’ path on KISSCC (# 7149);
Fixed a flash overflow on IMPULSERCF3 (# 7239);
Updated STM32F3DISCOVERY to support the on-board gyro and acc (# 7241);
Added support for on-board flash on MATEKF722SE (# 7257);
Added new targets CRAZYBEEF4FR, CRAZYBEEF4FS, and CRAZYBEEF4DX (# 7263);
Added new target STM32F411DISCOVERY (# 7289);
Added new target ELINF405 (# 7296);
Added new target RUSHCORE7 (# 7338);
Added new target FF_RACEPIT (# 7344);
Added pin for pinio use on PYRODRONEF4 (# 7389).
