Step 3 - Parameter Modification

In the root directory of the SD cards (this would be our FAT partition), theres a file called "uEnv.txt" in the top directory. Just for fun, lets understand what we're editing here too, in case we need to come back to it. According to this link, the uEnv.txt file "contains a series of parameters the user has put there and then the command boot on the last line, or alternately the commands uenvcmd= run loaduimage; run mmcboot." So when we modify it, we're modifying the parameters of our build before the system is booted.

  1. Open uEnv.txt
    gedit uEnv.txt
  2. Add the following line near the top of the code
    buddy=spidev
    This should enable the spi pins in the uboot
