Hi
I am building a new board and using STM32H743 and STM32F103.
I have defined SD card but my board is not interfacing SD card at all.
hwdef.txt (5.1 KB)
This is hwdef file of my board.
Is there anything else I need to define to use SD card?
I think you didn’t provide that much info(bus/port… ) to let us help.
- If you are using SDIO then you can take Pixhawk6C for example.
- If you are using SPI then you can take Aocoda-RC-H743Dual for example
Hope it helps!
– EDIT: I think you are using SDIO, so something like that. Check your pin number, I just copied from Pixhawk6C. (We have an FC to design, use SDIO also, I hope I didn’t miss any macros)
