    unto reacted to NeethuVP in Orangepi zero - External SD cad   
    Hi,
    I need to add a second SD card reader to my Orangepi zero. I tried with this link https://github.com/nopnop2002/STM32_TFT_8bit . But it doesn't work. I read that SPI is not enabled in Orangepi kernel and i checked with ls /dev/*spi*  and the output was - ls: cannot access '/dev/*spi*': No such file or directory.
    So i edited the /boot/armbinaEnv.txt as adding "overlays=spi-spidev" and rebooted. then checked ls /dev/*spi* and out is - /dev/spidev0.0. But my code is not working..Can you tell me what is wrong here ? These are my pin configuration
