Hi

with STM32CubeMX 5.1.0 on STM32F746BGTx there is an issue when I enable RS485.

Cube doesn't genrate all funtions related to RS485, for example the main inizialization function HAL_RS485Ex_Init is not present in the code generated by Cuce.

Attached the simple project file that generate the issue.

Best regard.

Hi

In fact the problem is that CubeMx doesn't copy the file stm32f7xx_hal_uart_ex.c in the folder Drivers\STM32F7xx_HAL_Driver\Src

A temporary workaround is to copy it manually from the CubeMx repository:

cube\repository\STM32Cube_FW_F7_V1.15.0\Drivers\STM32F7xx_HAL_Driver\Src

 to you project folder Drivers\STM32F7xx_HAL_Driver\Src
