STM32H7B3 bricked after flashing!

Hi,I'm trying to program code into custom PCB with STM32H7B3.I was first able to connect to STM32H7B3 (read Device ID etc.), but after flashing, the target cannot be found!ERROR: STM32: Connecting to CPU via connect under reset failed.I created code ...

What if callback function is interrupted?

On the STM32L0 I have a callback defined based on RTC alarms. In parallel I have a number of external interrupt (EXTIs) . Scenario Callback function is running due to RTC Alarm interrupt. Now EXTI is triggered as well (or visa verse -> EXTI function ...

I can jump without problem inside the main memory and boot a second software. Can I do the same thing with the SRAM1? I've copied data from main memory (0x0802000 to SRAM1: 0x20001000), but I can't jump to that address

Different ADC's VREF

Hi all,I am working with the ADC of the STM32G484 microcontroller, and I would need to have two different reference voltages, in order to gain resolution.I can't find anything about this in the datasheet, so it leads me to think that it is not possib...

Is there an SRAM example code module around to drive static SRAM in the L4R5 CPU?

Now that there is an STM32 cpu chip with larger on-board memory, I would like to make use of it, but I have not found any working examples in that line. Reading the SRAM module in the HAL driver section is not much help.

I am a beginner, I will use the STM32F107VCT6. I have 2 paths. A Stm32-comStick from Hitex and on the other hand a ST-LINK (from 2011) with a Waveshare socket. Can these paths be taken with the STM32CUBEMX? Please advice.

Stm32f072 external interrupts more than one

In my project am using A mcu , and wanted to use pA0 and Pc13 as two interrupt.​But interrupt for pA0 is not coming and Pc13 is coming.​Please help to know the cause.​Rohit+91-8141616356​

How do I get my flash programmer to reset an STM32G070 after programming it, so that I do not need to cycle power to run the just-download code?

I've tried using IAR and the Segger Flasher to program an STM32G070. However, neither programmer will reset the MCU, so that I do not need to cycle power to run the just-download code? I've seemingly tried every type of Reset. What am I missing?

i use the stm32h750b-dk\demonstrations\toughgfx\mdk-arm\project.uvproj perform assembly, no issue. then perform Download, i increase the ram for alogorithm size, and add MT25L01G_STM32H750B-Disco, erase - > programming - > verify. All ok, no issue.

How can I read all the used ADC channels spread out on all three converters?

I have a configuration where I have 24 single-ended ADC channels distributed on all three ADC channels.I have not found any example how to read more than one channel.All channels should be read every 20ms, so there's enough time. But I don't know if ...
