Hi,   I have a firmware runing on STM32F405RGT6 whith is reloacted at 0x800C000 and is called by a bootloader. The problem is if I enable UART DMA, the program will be interrupted by non stopping DMA interrupt immediately. However, there is no stream...

Hi ,   I made a STM32F405VGT6 board with SD card interface. The SD code is generated using STM32CUBEMX and FatFs middleware.   The SD file write is not stable, it return error sometimes after calling f_write(). However, if I run the same code in uVis...

We connect STLINK/V2 to STM32G071 with 3 wires : SWDIO, SWCLK and GND. It always failed to connect. However, we can connect by using JLINK. We notice that STM32G071 combines the boot0 with SWCLK. Does this make STLINK/V2 failed to connect ? How can w...

It seems there is a mistake in STM32Cube\Repository\STM32Cube_FW_L4_V1.13.0\Projects\STM32L4R9I-EVAL\Examples\OSPI\OSPI_NOR_MemoryMapped project, the STM32L4R9I-EVAL board flash chip is connected in OCTOSPI1, but in this project, the instance is OSPI...
