Hello every one, I have a problem about connecte micro Sdcard. I use FS_Init() then:
Firstly, I use funtion : FS_GetVolumeName(0u, &sdVolName, 9u), I have name Sdcard is "mmc".
Secondely. I use funtion: FS_Mount("mmc") , I have value -1 (Erro, Volume can not be mounted)
Please Tell me why? I dont read or write any file to/ from micro sd.
Thank so much!
Probably not all MicroSD cards support SPI
My microSD cards (> = 16Gb) also do not work with SPI
I use the SD <= 4Gb
Hello pavloven, New start, I think like you, MicroSd cards not support spi or zerror spi.
But Then, I conneted MCU with Microsd card by spi protocol, and send some command to Micro Sd, Micro Sd return true. so, spi of Micro Sd card alway run. :))
