Prerequisites for cross-compiling

Host PC

• Recommended OS is Ubuntu 18.04 LTS
• You need git to clone this repository
• All other packages are installed by the scripts contained in this repository

Installation

1. Create a directory and clone the repository.

     $ cd <working_dir>
     $ git clone https://github.com/pmliquify/vc_mipi_imx8mm
   

2. Setup the toolchain and the kernel sources. The script will additionaly install some necessary packages like build-essential and device-tree-compiler.

     $ cd vc_mipi_imx8mm/bin
     $ ./setup.sh --host
   

3. Build the kernel image and the device tree file.

     $ ./build.sh --all
   

4. Flash the kernel image and the device tree file to the target and reboot.

     $ ./flash.sh --reboot --all
   

5. Login and check if the driver was loaded properly. You should see something like this in the second box.
