Hi Ahmad, Did you add support for your custom board correctly? This that come to my mind:
1) Did you have configured and enabled the right source clock? 2) Did you have configured the right pins at boards/arm/stm32f7/yourboard/include/board.h ? 3) Did you create a similar file like boards/arm/stm32f7/nucleo-144/src/stm32_sdio.c to detect and initialize your card? or boards/arm/stm32h7/linum-stm32h753bi/src/stm32_sdmmc.c (although it is STM32H7, it is very similar). 4) Did you enable all necessary configs to your board? It is similar what we have to STM32H7 board: boards/arm/stm32h7/linum-stm32h753bi/configs/sdcard/defconfig Best regards, Alan On Sun, Apr 14, 2024 at 11:13 AM Ahmad Noori <ahmad77...@gmail.com> wrote: > Hi > > I have a custom board with stm32h743vit6 > I port nuttx to this board and i am using it. > I have problem with mmcsd sdio and i cant mount sd card.
