Compilation error due to missing UART_HandleTypeDef struct name
Hello everyone,
I am currently working on a project with a STM32U545. There was a first prototype electronics + software that was working. I made a new hardware and I wanted to use the same code with just a few modification.
For this, I just copied the STM32CubeIDE project, modified the configurator with the integrated CubeMX, regenerated the code and compiled.
This is where I ran into problems:
I have this compilation error:
../Drivers/STM32U5xx_HAL_Driver/Inc/stm32u5xx_hal_uart_ex.h:231:36: error: unknown type name 'UART_HandleTypeDef'; did you mean 'RTC_HandleTypeDef'?
231 | HAL_StatusTypeDef HAL_RS485Ex_Init(UART_HandleTypeDef *huart, uint32_t Polarity, uint32_t AssertionTime,
| ^~~~~~~~~~~~~~~~~~
| RTC_HandleTypeDefSTM32Cube IDE version: 1.18.0
STM32CubeMX version: 6.14.0
When looking at the generated driver (file stm32u5xx_hal_uart.h), I noticed that the UART_HandleTypeDef was missing its name before the semicolon:

}; // MISSING STRUCT NAME!I tried deleting the file and relaunch code generation but it did NOT solve the issue.
Do you have any lead?
Thanks a lot,
