Im currently trying to use an SD card in one of my projects.
PSoC Creator 3.3 CP2, Component emFile 1.20, Lib emFile_V322c.
I am using an Lcsoft.net SD Card holder (see the schematic attached) and a PSoC5LP Prototyping Kit. I already measured all the physical connections, tried another SD-Card holder, other boards, other pins, other libraray configuration... no success so far.
I used the Demo-Project and as well tried to set up an empty project with the instructions from the emFile datasheet.
I have used exactly this SD-Card (32MB SDXC/MMC) some years ago with PSoCs and it worked fine. Also the card is not write protected and works fine under windows.
I also Included FS_ConfigIO.c to my project and inserted UART Debug statements there but there is nothing coming out. My code (based on the example)
/* Get volume name of SD card #0 */
if(0 != FS_GetVolumeName(0u, &sdVolName, 9u))
/* Getting volume name succeeded so prompt it on the LCD */
UART_PutString("\r\nSD card name:");
/* Operation Failed - indicate this */
UART_PutString("\r\nFailed to get SD card name");
UART_PutString("SD card format: ");
if(0 == FS_FormatSD(sdVolName))
/* This will create directory "Dir" on SD card */
if(0 == FS_MkDir("Dir"))
/* Display successful directory creation message */
/* Display failure message */
UART_PutString("\r\nFailed to create directory");
SD card name:mmc:0:SD card format: Failed
Failed to create directory
Needless to say that also the card is not formatted and no directory created.
Its a bare-metal system without OS. I tried emf16nosnlfn emf32nosnlfn and emf16noslfn

I attached a logic analyzer to the borad, this doesn't look like proper SPI communication to me (see attach file).
