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...
Hi ST Team,We are using CAN on STM32L562 in classic mode.After configuring, we se FDCAN.PSR.ACT to be 1 as can be seen in screenshot below.This means, node is neither receiver nor transmitter.Why is this happening ? We are able to receive the data, b...

Hi,We are facing the same issue like the below community post. https://community.st.com/t5/stm32-mcus-products/flash-via-i2c-bootloader-problem-for-stm32g0b1kbu6/m-p/636467#M234685 But we are using 'STM32G431RBT6' in our project, kindly let us know ...
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 ...
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...
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...
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...
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...
