SPI between F769I and F446RE not working

Hi,I'm trying to implement a basic SPI full-duplex between two STM32.I have set up an F769I as Master, which works just fine. However the F446RE Slave doesnt transmit anything.I used CubeMX to create the project (file attached).The Master currently d...

Bug report: STM32F4 Cube 1.18.0 HAL CAN driver generates incorrect code.

Cube 1.18.0 appears to generate HAL CAN code in can.c and can.h which is aimed at the 1.21.0 redisigned CAN driver.The code refers to member variables which do not exist in the 1.18.0 register structures, for example: hcan1.Init.SyncJumpWidth = CAN_S...

LoRaWAN Rx2 timeout not being triggered for confirmed messages
