1.  Determine the SD card device name

   1. The SD card device name is of the form /dev/sd[b|c|d|e]. Run the following without and with the SD card connected:

      Code Block
      language bash
      ls /dev/sd*

      
      

   2. The device that appeared on the call to ls with the SD card but not the call without is the SD card device.

2. Unmount all partitions of the SD card, using the SD card device name from Step 1: 

   Code Block
   language bash
   umount /dev/sd[b|c|d|e]*

   
   

3. Load the SD card image onto the SD card from the linux command line. This will format the appropriate partitions, as well as add U-Boot, the kernel image, and the root filesystem to the card.

   1. From the directory that contains the '.sdcard' file, execute the following command:

      Code Block
      language bash
      sudo dd if=fsl-image-gui-<MACHINE_NAME>.sdcard of=/dev/sd[b|c|d|e] bs=1MB && sync

      
      

...

1. If modifying the kernel, remove the existing zImage and device tree binary files:

   Code Block
   language bash
   rm /media/<user>/Boot\ imx7-p/zImage rm /media/<user>/Boot\ imx7-p/<MACHINE NAME>.dtb

   
   

2.  Load the new Linux kernel and device tree binary to the SD Card:
    

   Code Block
   language bash
   cp zImage /media/<user>/Boot\ imx7-p/; sync cp zImage-<MACHINE NAME>.dtb /media/<user>/Boot\ imx7-p/<MACHINE NAME>.dtb; sync

   
   

...

1. If modifying the root filesystem, remove the existing:

   Code Block
   language bash
   sudo rm -rf /media/<user>/<rootfs partition>/*

   
   

2. Load the new filesystem to the SD Card:

   Code Block
   language bash
   sudo tar -jxf fsl-image-gui-<MACHINE NAME>.tar.bz2 -C /media/<user>/<rootfs partition>/; sync

   
   

...

1. Flash u-boot to the SD card:

   Code Block
   language bash
   sudo dd if=u-boot.imx of=/dev/sd[b|c|d|e] bs=512 seek=2 conv=fsync
