STm32H563 RS485 DE-Configuration in CubeIDE

[pit0815]

Hello,

in CubeIDE (MX) RS485-direction switching is only selectable for UART4 and UART5 (by hardware, not by SW-GPIO). According to user manual, it should be possible for all UARTs/USARTs (Pin DE/RTS). Is this feature missing in CubeIDE or is this hardware-feature only available for UART4/5 (manual is incorrect)?

Regards

Steffen

Your detailed explanation is much appreciated.

A ticket  183549 has been submitted to our dev team in order to fix this asap .

I can confirm, that for UART7 and USART6, the Checkbox "Hardware Flow Control (RS485)" is missing. For instance, this is how USART11 looks in my project, using the STM32H563RITx:

And this is USART6, which misses the HW-Flowcontrol configuration options:

Are there any news from the ticket you submitted?

Any solution, we have the same problem

Can't DE be enabled in code, regardless of CubeMX?
