求万利EK-STM32 的FATFS 移植好的KEIL MDK软件包

自己移植到出现 FILE NO SYSTEM . 搞几天没头绪了！
也发觉这个FATFS 系统经常改变。变来变去的，从R0.06---R0.09 0.09A /B.....

各位有没有万利EK-STM32 的FATFS 移植好的KEIL MDK软件包，请发一个!
谢谢！

你自己找万利就好了

万利木有。只是SPI读SD的接口驱动而已，没有完整的FATFS KEIL MDK包。

万利也不过是个小公司，没有这么多人精力来开发软件的啊！

disk_sta=disk_initialize(0);//disk_status
f_mount(0, &fatfs[0]);
f_open(&fsrc, "0:/ABC.TXT", FA_CREATE_NEW | FA_READ);

出现
FR_NO_FILESYSTEM,             /* (13) There is no valid FAT volume */

本人使用SPI1 硬件和使用 IO 软件模拟SPI1读都是这样！

开发板就是万利电子的 EK-STM32F
