Elm Chan's FatFs R0.09 kullanıyorum STM32f407'de sdio ve dma kullanılıyor. Kütüphane 512MB'lık micro SD kartlar ile çalışıyor sadece, 2GB, 8GB denedim çalışmıyor. Debug ettiğimde aşağıdaki fonksiyonda takıldığını görüyorum.

adetli bir ürün vereceğim 512MB'lık kartlar gereksiz pahalı, çinden getirteceğim son çare olarak ama bu sıkıntıyı yaşayan oldu mu daha önce ?

#1
2 TB desteği var kütüphanenin format olarak FAT32 veya ExFAT kullanmalısınız.

ayrıca 0.13 versiyonu güncel olanı http://elm-chan.org/fsw/ff/00index_e.html sitesinden indirebilirsiniz.

http://elm-chan.org/fsw/ff/doc/appnote.html alt kısımda kartın uyumluluğunu kontrol etmenize yardımcı bir program var onunla ayrıca test edebilirsiniz.

ffconf.h içindeki ayarlarınızı da koyabilir misiniz?

kartlarda fat32, fat, exFat denedim sonuç aynı. ffconf.h içeriği :
