Hello there, I'm using USB CDC application. I'm in a situation of receiving more than 250 bytes of data from the Windows(QT). Now my doubt is when the data is more than 64 bytes the USB FS it'll not consider right.But i revised some websites from the...
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 ...
Edited the post to follow the community guidelines. In next time please use </> button to paste your code. See this post. Hello Experts, I am unable to read the byte of data from eeprom in particular address after written the data.i am getting the r...
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...
