STM32F4 SDIO sorunu

[Sya]

Arkadaşlar merhaba, stm32f4 ile sdio üzerinden sd kart haberleşmesi yapmaya çalışıyorum fakat bağlantıların doğru olmasına rağmen kod

if(f_mount(&fat,(TCHAR const*)SD_Path,1)==FR_OK)

bu döngünün içine giremiyor. 8gblık FAT32 sd kart kullanıyorum.

Bu da kodun tamamı.MOSI çıkışında sabit 3.3v görüyorum herhangi bir pwm yok.

Not:Bunu yaptıktan sonra spi ile haberleştirmeye geçeceğim.

Merhaba, sorunu çöze bildinizmi acaba? Aynı sorun bendede var.
