@ionic fulcrum The "THROTTLE" disarm flag means the throttle wasn't low enough to arm. Betaflight won't let you arm the drone if the throttle isn't near zero.

@ionic fulcrum For some reason you have bitbanged DShot enabled. The CADDX_PROTOS_F4 target explicitely disables that due to an issue with DMA2 on the F405 MCU.
Now your gyro SPI bus doesn't have DMA enabled, which is bad.

#

Please set dshot_bitbang to OFF
