I've a problem with my STM32F217VG. I need to use fat filesystem on MicroSD card (2 GB) to read/write/create files.
I tried to use Chan FatFs module but it didn't working at all ...
I use SD card in SDIO mode.
When I debug: I call the sub "f_mount" and return an error! I follow the problem inside : "disk_initialize" >> "SD_Init" >> "SD_PowerON" >> "CmdResp3Error" return always "SD_CMD_RSP_TIMEOUT" ... with or without MicroSD !!!! I'm desperate :-(((
1. I don't know if the subs "SD_Init", "SD_PowerON"... are the right ones! Where I can find the correct sub for my STM32F217 ?
2. What could be the problem ?
