I'm working on Custom boot loader based on Openbootloader by ST, existing example is based on STM32G0/G4 series but I'm using STM32F417 and there are losts of differences in terms of internal flash memory architecture(G0 to F4 series) and HAL/LL libr...
Good morning everyone,I’m trying to get FDCAN working on a STM32G431 however with very limited success. I’m not able to get a valid output signal on the TX line (measured with an oscilloscope) however, if I put the FDCAN peripheral into External Loop...
Hi,I am working with STM32G491RET6 custom board and for debugging I am using segger jlink debugger with STM32 Cube IDE 1.13.0. Everything working correctly like flashing and debugging.1.But I don't know what happened suddenly while debugging program ...
I will use the STM32U575 with OCTOSPIM as Quad SPI (master) adapter.Q: The DQS signal is intended for DDR mode (I know).Could I use also DQS as input in SDR mode (when OCTOSPIM acts as SPI or QSPI master)?Idea:I want to compensate the "Round Trip Del...
hello, I ues OCTOSPI device in STM32U545, it just generate cs and clock wave when run this code.HAL_OSPI_Command(hospi, &sCommand, HAL_OSPI_TIMEOUT_DEFAULT_VALUE)But io 0-3 nothing happened.I have reference the examples, it's use OCTOSPIM what not in...
Hi guys,When setting option bytes to boot device from internal flash (at 0x0800_0000), the entire Flash memory region is aliased to start at address 0x0000_0000. But the mapping address of ITCM is starting from 0x0000_0000 to 0x0000_FFFF, so I wanna...
Hey everyone!Some context:We are developing a medical device using STM32H7ZIT6 MCU. We succesfully developed a working prototype, using UART connection protocol. Couple of consistency problems (i.e. the device works flawlessly at times, sometimes we...
I have reviewed the many posts from others that have not been able to jump from a bootloader the application code and nothing that I tried worked.My MCU has its 128kB of flash in two banks, one at 0x08000000 and the other at 0x08040000. When the MCU...
Hi All, I'm using an STM32F1 with a 240x240 LCD screen that comunicates with the micro by SPI (with DMA). The screen uses the ST7789 driver (I supose it is not important). I'm working with RGB565 color format.The problem that I have is, for example, ...
Hi, I observed a limitation in the STM32H7 reference manual saying that "The current version of the SDMMC supports only one SD/SDIO/e•MMC card at any onetime and a stack of e•MMC."So my application requires to control two SDIO slaves from both SDIO i...
