STM32H7A3AII6Q Internal bootloader boot for firmware update.
Hello, I'm working into writing firmware image to a STM32H7A3AII6Q via internal boot-loader. I'm using AN2606 and AN3155 as reference documents. The boot-loader entry sequence I'm using:State 1: BOOT0: high RST: lowState 2: Wait 2...
STM32L051C8 comparator consumption
Hi,I have a strange problem on an STM32L051C8 with the comparators enabled in window mode.If I put the system in stop about 20 seconds after powering the microcontroller, the current draw is about 250 uA. If I then exit the stop mode with a soft rese...

Hello, everyone on the forum.I am using ThreadX and FileX to write files to an SD card on the STMH735G-DK.I successfully created a directory using fx_directory_create and created a file using fx_file_create.This time, we'll tackle directory deletion ...
Trying to source a 12.288MHz clock for STM32L433
I am trying to source a 12.288MHz clock for an STM32L433 but having difficulties finding something.The clock is required for I2S playback with a bluetooth receiver (BT401).I have tried using the internal MSI RC to generate the 12.288MHz clock for SA...
STM32H723ZG Nucleo Board 144p, Super Low Power Consumption, Probably on Standby >10uA
Hello, I want to use the STM32 H723ZG Nucleo board 144p in my LoRaWAN project. For that, I need my microcontroller to consume less than 10uA of current in standby or sleep mode. Is that achievable? If yes, then,1- What will be the hardware?2- clock c...
STM32U5 DCMI DMA is not working as expected.
Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. T...
STM32N6 VENC Hardware Handshake with MJPEG encoding
The VENC peripheral on the N6 boasts a hardware handshake path with the DCMIPP peripheral, potentially allowing full compression of each frame to occur with very little active RAM. From what I can find, the DCMIPP capture starts, then the VENC is tol...
