stm32f334 HRTIM STM32CubeMX bug

Hi.

 

I want to use the A HRTIM timer to independently control two MOSFETs. Namely, I have a transformer with the midpoint connected to the positive pole of the power supply, and these two transistors switch the 2 halves of the winding as lower switches to generate 2 half-waves of a sine wave.

But I can't configure it in STN32CubeMX for the second output the condition for set. STN32CubeMX "Set Sources: nothing to set as Dead Time is enabled, Output2 signal is defined based on Output1 Configuration Set Sources must be 0." although the channels are configured as independent. Moreover, before the update there was no such problem. Now STM32CubeF3 Firmware Package V1.11.5

Why the problem?

Hi.

I opened the project using STM32CubeMX version 6.15, where there were no errors. In STM32CubeMX version 6.16 - this shows the errors.
Of course, I can fix the code manually, but this is not good, because when changing in STM32CubeMX, the changes will be replaced by the old code and you will always have to remember what needs to be changed. This spoils the whole idea of ​​using the graphical configurator.

What is the status of the ticket?

For anyone facing the same problem, the conditions preventing changing the sources are in STM32CubeMX/db/mcu/IP/HRTIM-hrtim_H7_Modes.xml

You can disable the checks there as a temporary fix.

Cheers, Lukas
