I'd like to use a ST-Link Utility to extract F/W

I'd like to use a ST-Link Utility to extract F/WThe device I'm using is the "STR736FV0T6"and I have ST-LINK/V2 and ULINK2The other day, I had an experience of extracting the one on the STM32F205 device.Isn't STR736 supported?I want to know which JTAG...

RTC with LSI only starting up when code is launched by debugger.

I am using an RTC to wake up my MCU from shutdown mode. RTC is configured to use LSI clock, which runs during shutdown. When I run my code from a debugger, it works fine. Goes to sleep, wakes up from shutdown when the RTC pings it awake. I can see th...

Where is STM32H735G-DK full .hex file as supplied from the factory?

There's a file STM32Cube_Demo-STM32H735G-DK-V1.0.0 on the website, but it's not the one referenced in the accompanying .bat file (which has a name ending in "FULL") and seems to just (sometimes) load up the selection screen but mostly gives me a blan...

About half-duplex communication (Rx frame size is 3)-2

Hello,Is it possible to perform half-duplex communication like the attached document? (I understand that the timing to switch to Rx is tricky.)The Rx frame size is 3 instead of 1.After changing to Rx, can I receive 3 bytes continuously as shown in th...

What happens when a STM32H747 encounters a skipped clock pulse on its HSE clock input every few million cycles?

I wonder if a regularly or sporadically missed clock pulse on the HSE clock input has any (negative) effect on the operation of the H7 processor or any clock output from a HRTIMER.My guess is that the internal PLL might lengthen the next pulse a litt...

Hi, I am working on STM32F769i-DISCOVERY board. I am quite new to it. I have to implement a transmitter which sends square wave. How can i generate square wave.

Is it possible to reset the CM4 from the CM7 on the STM32H747?

Or at least make software reset work on only one core?Thanks

Connecting PWM output to input on the same board

Good day everyone,At the moment I'm trying to connect a PWM output pin to a PWM input pin on the same board. I'm using a dual core MCU, so both of them are on a different core.I set TIM4 to the M7 and TIM15 to the M4. I enabled the interrupt for TIM1...
