Resolved! synching HRTIM's TIMA and TIMB

Trying to make a phase shift PWM for a DAB converter, i managed to do this exact functionality with normal TIM1 (Asynchronous mode), but im very very lost with HRTIM. I am able to produce complementary PWM signals for TIMA1 and TIMA2, and TIMB1 TIMB2...

Open bootloader for STM32H747 on USART

I want to use open bootloader on STM32H747 controller. I found that ST provides support for STM32H5 but not STM32H747. Can I use it for STM32H747? How can I port to my target controller?

STM32 NRST line

Hi,We are using STM32L452 for our project.We have problem with pin NRST.We set a 30K pull-up resistor (with pull-down capacitor of 0.1uF).Sometime voltage on the NRST pin is 3.3V and sometimes it is 1.4V.In cases it is 1.4V the MCU is stuck.We think ...
