Hi, I am using STM32H743ZI Nucleo 144 board for one of my application. As per the observations I got the utilization factor with STM32H743 is 35% where as with STM32H752 it was 60%. We have not initialized any crypto or secure features on STM32H753 b...
Hi, On STM32G071CBU6, when PB15 is used as CC2 with DBCC2 shorted to CC2, does the ROM bootloader ever drive PB15 as SPI2_MOSI, or does the CC/dead-battery own the CC2 pin and that path always takes priority? This detail is critical for our design be...
Hi. I'm trying to read data from w25q64. When i erase and write the chip and then read it, i receive true data.But when i only read data, my chip is blank and i receive 0xFF.Is my chip still blank or i wrote the chip correctly?Why don't i receive tru...
Hi, I'm using a Nucleo-F446RE Board and I'm trying to set up a basic DAC with DMA configuration without HAL-libaries.The configuration without DMA works just fine, I can measure correct voltages with my oscilloscope on PA4 as intended. My following D...
Hi. I'm trying to read data from W25Q64 flash memory.These are my connections:And these are my SPI and RCC and GPIO settings:And these are my functions and main code:Using W25Q_ReadID function, i could read device ID.But i can't read data stored on d...
Hi everyone,This is a follow-up to my previous question about LED behavior on the STM32H755ZI-Q when using OpenAMP communication between CM4 and CM7.https://community.st.com/t5/stm32-mcus-boards-and-hardware/nucleo-h755-led3-not-turning-on-pb14-in-ip...
Hello ST experts,I have a weird experience with UART communication between two STM32G4 microcontrollers. MCU1 sends 10 bytes to MCU2 via UART. Both UARTS are configured with 9600 Baud rate with DMA in circular mode. The Problem arises when the MCU1 i...
Hi, everyoneI recently encountered a strange phenomenon. I opened three DMA channels on the STM32G474RBT6.The first one is Channel 1 of DMA1 (circular mode), which is used for automatically collecting the data converted by ADC.The second one is chann...
In my embedded software project, I need to write a bootloader. I wrote an application code for the bootloader and testing, and everything is fine so far, but the delay function in the application code is not working. I think the reason for this is th...
I am designing a system that will utilize the dual bank feature of the STM32 devices to make a robust system for OTA updates. I am currently using a STM32U545 for my project and have questions about writing to the FLASH_OPTR to change the SWAP_BANK b...
