STM32L452xx Bootloader on UART4
I'm looking at AN2606, section 65.1 and it looks like UART 4 can NOT be used by the bootloader to load FW into the part. Can someone confirm that is true?

I3C error in transmission/reception process - NUCLEO-H563ZI
I am using 2 Nucleo-H563ZI boards, one as controller and the other target, and referencing the knowledge base post "How to set up and run the I3C_Private_Command_IT controller and target example projects" yet I am getting an error. From what I can te...
Resolved! Núcleo-H755zi spi with NRF24L01
I'm trying to use Núcleo H7 spi 1 to send a message via radio with NRF24L01, the code using HAL worked perfectly on an Stm32F103 but when i try adapting it to the Núcleo it just don't work. Can somebody help me up? The SPI clock is 100MHz , the core ...
nRF24L01 transmitting only 10-15 times per second, and the data is multiplied by two
I'm trying to write a driver for the nRF24L01+PA+LNA. I am using STM32F103, and on the receiver side I have an ESP32 with Arduino IDE and the RF24 library. To rule out a hardware issue I have programmed the STM32 using the Arduino IDE and library and...
STM32H7 SPI6 not working with DMA
Hello team, We have another challenge with STM32h725 controller, What I am trying to do and achieve is, Setup few external ADC over SPI bus with DMA. The ADC on SPIs other than SPI6 works perfectly. But the SPI6 is not with regular DMA but with BDMA....
Driver IHM16M1 burnt pin?
In the lab with a power supply (10V 0.5A) connected to the DC bus of the IHM16M1, the 3 phases of a DC motor, and some oscilloscope probes on the GPIOs of the STM32F302R8 I probably created a short (I don't know how, I deduce).I deduce this because n...
Resolved! STM32H5 RTC count through power cycles
What is the expected RTC peripheral behavior through power cycles on VDD? We have a 3.3V system design with the STM32H562VGT6 right now.Setup:VDD = 3.3V from external supplyVBAT = 220mF supercap attachedRTC is enabled & counting, system is stableLSE ...
STM32 Digital Input Pullup Glitching Issue
Hi,I have an application where I am trying to read some pulsed inputs from an optocoupler (for isolation) which consist of pulled high inputs on the STM32 MCU, the problem is it keeps crashing when connected directly to the optocouplers randomly when...
SPI DMA Receiving buffer is not filled
Hello,I'm trying to setup a SPI communication through DMA but I can't receive data.I use a STM32H7 microcontroller as a single master to reach a single slave. I would like to transmit 1 byte, and receive 1 byte in return. To start the transfer, I cal...
implementing wake up from stop via ethernet mechanism
We apologize for changing the subject again and not responding to your request, but today we discussed this project with our teacher, who told us to first focus on the implementation of Wake on LAN and to be satisfied with putting the device in stand...
