I have a project based on the L496. The application does a few writes to FLASH. The initial write works correctly, however subsequent writes fail. The code is directly from STCube:/** * @brief Wait for a FLASH operation to complete. * @param Ti...
Posted on January 25, 2018 at 14:07Hi,I use STM43L476 and try to use fast flash program to program 256 bytes (decripted_firmware_data buffer).The flash area is erased (all 0xFF), but the function HAL_FLASH_Program always returns with HAL_ERROR and n...
Hi everybody!I'm trying to acquire data from the ADC1 with two channels, and store them in a 40k long buffer with Circular DMA.The problem is the following: it seems that every about 3k samples the ADC stops workinkg for a while and then starts again...
Hello ST Community,I use two UARTs at the same time, 1 to communicate with a sensor and the other to communicate with the BlueNGR-M2SP BLE module.The UART2 is configured with DMA IDLE because the length of the frame I receive varies and the UART1 has...
I have an application on STM32H750 which runs out of QSPI in XIP mode. After init, I enable the cache with SCB_EnableICache() and SCB_EnableDCache(). After this point, the application goes to a continuous loop which just calls the same small function...
Hi,I am using STM32H743VI MCU for running a BLDC motor. When I debug and run the code without connecting the motor then I can able to debug the code and I also printing some messages on the UART, its working fine. As soon as I connect the motor with ...
I am using the STM board as STM32H745 controller . I taken One example program and I am able to transmit the data through the UART. But I also need to receive the data which is coming from the putty through the UART and it should be in the interrupt ...

Hello,I'm posting a question to get advice on a problem about communication with UART using DMA.I wrote code like followings : Transmit data only when HAL_DMA_STATE is ready. if(HAL_DMA_GetState(hdma) == HAL_DMA_STATE_READY) HAL_UART_Transmit(hu...
