Good Day,Recently I started working with a new MCU (STM32L152). I ported some UART code to handle received data from a different MCU, which worked fine. But as soon as I started testing edge cases I saw some weird things happen. I am using the DMA on...
Hi,I am implementing RS-485 communication on the STM32G491. Based on available references, I’m currently using a custom GPIO pin for the DE (Driver Enable) signal, since the default USART1_DE pin is already allocated for another function. In the RS-4...
Two of my MCUs are halting in same problem after running for about a year. There have not been many writes/cycles as I have a erase cycle counter which shows 27 so its not wear out problem. The EE_Init function gets stuck at step 4 and returns with ...
Our product requires FIPS certification, and the chip is stm32u595. I found that the stm32 cortex-m33 core already has a library certified by the CAVP algorithm, but the version of the STM32CubeExpansion_Crypto-V4.2.0 library does not match the certi...
I want to write data to an external flash (w25q128 with SPI) by sending a hex file from a PC to the STM32 over UART using tools such as Realterm or a python scriptI have seen examples using the external loader with STM32CubeProgrammer, but I want to ...
Hi team,We are working on the custom bootloader on stm32u073RC. not able to jump on the specific location.#define APPLICATION_PARTITION_1 0x0801D000 void jump_to_application_partition_1(void) { /* Disable Interrupts */ __disable_irq(); ...
I am trying to add the NUCLEO-N657X0-Q (MB194-N657X0Q-C01) to the IMBootloader project, which currently uses the Legacy Classic USB device middleware. I ran into a problem where, after calling the HAL_PCD_Start() function, I receive an unexpected int...
Hello,I followed https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308 tutorial from the scratch to the end, including the Hello UDP part, and adding the "ETH CODE" code.However, I can't pi...
Kindly confirm whether STM32H723VGT6 supports Zephyr using the NUCLEO-H723ZG evaluation board.
Hi,I’m using the STM32U5G9J-DK1 board and working on implementing a FileX-based filesystem on the onboard eMMC. On the first run, I format the eMMC using fx_media_format(), open the media, create a file (e.g., file1.txt), write data to it, and read i...
