Other Parts Discussed in Thread: CC3200

I want to connect using MicoSD FatFS library through SPI. In the process I realized that the same SPI Flash Memory is connected to the FLASH SPI loader.
How is this situation? How do I do to connect and MicroSD and Flash SPI?

    Hi,

    No, PINs for SFlash and SD card interface are not shared. Please read datasheet for CC3200 carefully - www.ti.com/.../cc3200.

    - SFlash interface use pins (at QFN package): FLASH_SPI_CS (pin 14), FLASH_SPI_DIN (13), FLASH_SPI_DOUT (12), FLASH_SPI_CLK (11).
    - SD card interface use: SDCARD_CLK (1 or 7), SDCARD_CMD (2 or 8), SDCARD_DATA (6 or 64) and SDCARD_IRQ (63).
    - Alternative you can use SPI peripheral: GSPI_CLK (5), GSPI_CS (8 or 50), GSPI_MISO (6 or 53), GSPI_MOSI (7).
