Code always returns rc = 3 (FR_NOT_READY), using both SSI1 and SSI3
Also, if using SSI0 and SSI2, f_open causes a Fault interrupt.

Hello Rohit,

I'm using your code on my TM4C123GXL TIVA C series board and got the below prints on serial port.

f_mount success!
f_open error

What could be the problem ?
I've used TOSHIBA 16GB microSD card....
Any limitations for this code ?
Can you please help me on this issue ?

Also getting this issue without connecting microSD card into board :(

As per the code, I've usesed SPI3.

// GPIO for SSI pins
#define SDC_GPIO_PORT_BASE GPIO_PORTD_BASE
#define SDC_GPIO_SYSCTL_PERIPH SYSCTL_PERIPH_GPIOD
#define SDC_SSI_CLK GPIO_PIN_0
#define SDC_SSI_TX GPIO_PIN_3
#define SDC_SSI_RX GPIO_PIN_2
#define SDC_SSI_FSS GPIO_PIN_1
#define SDC_SSI_PINS (SDC_SSI_TX | SDC_SSI_RX | SDC_SSI_CLK | SDC_SSI_FSS)

Thanks for your help.

Regards,
Titus S.
