Unable to debug in STOP mode - Break at address "0xa05f0000" with no debug information available
Hello, I'm trying to debug my NUCLEO STM32H7A3 in STOP mode and run into this problem:When I set a breakpoint after the STOP mode, the breakpoint is hit correctly and everything works as expected, even step in or step out, but when I click on RESUME ...
STM32H743 Battery backed ram issue - ideas wanted
I'm using the 4K of battery backed RAM on the STM32H743 to preserve variables between power cycles. This works fine on 90% of identical systems running identical firmware and with identical H/W, identical chip versions etc. i.e. data is exactly what ...
STM32H7 SDMMC2 DMA Configuration
I can configure MDMA for SDMMC1 in STM32H730 in STM32CubeIDE.But I do not understand how to enable it for SDMMC2. In the documentation it says SDMMC2 has a direct access to DMA1 & DMA2. But I could not see it in DMA configuration panel.Could you help...
How to transfer a File which has (.AMR) Format from UART1 to UART2 ??
Dear Sir,I am Using STM32G030C6T6How to transfer a File which has (.AMR) Format from UART1 to UART2 ??
Resolved! Can't find the X3 crystal recommended by ST from any supplier, nor can I find an equivalent that is in stock from any supplier.
Hi,I have a STMF32446ZE board and require an external crystal that isn't using the STLINK crystal. For x3 ST recommend the following: NX3225GD-8.000MEXS00A-CG04874The specs of this crystal are: Frequency Stability ±50ppm Frequency Tolerance ±20ppm ...
printf on STM32H747 core M4 doesn't work
printf works on the STM32H747 M7 core once I add the following codeint _write(int file, char *ptr, int len) { int i =0; for ( i = 0 ; i < len; i++) { ITM_SendChar((*ptr++)); } return len; }and enable the "SWV" in the debug...
Does HAL_UART_Transmit() sends ASCII or binary?
Hi! Does anyone know if HAL_UART_Transmit() sends ASCII or binary? I've tried to send some data a serial plotter but nothing is being plotted. The format of the data sent follows the setting in STM32CubeMx. (It works on Arduino serial plotter)Serial ...
Resolved! I'm using SPI to communicate with a MIPI chip, the commands to the MIPI are sent as 9 bits but the data sent back is 8 bits.
I'm using SPI to communicate with a MIPI chip, the commands to the MIPI are sent as 9 bits but the data sent back is 8 bits. The 9 bit are set up in a uint16_t variable. Using HAL_SPI_Init the data size is set to 9 bits. When I receive the data using...
