DART-MX8M-MINI - Customizing the Debian Linux kernel
This section describes how to build a new kernel configuration using menuconfig and deploy it.
Configuring the kernel
The default kernel configuration file used by Debian is part of the kernel source tree and is located at:
~/var_mx8mm_dart_debian_buster/src/kernel/arch/arm64/configs/imx8_var_defconfig
To configure the kernel using Debian:
Modifying the kernel configuration
To modify the kernel configuration (add/remove features and drivers) please follow the steps below:
$ cd ~/var_mx8mm_dart_debian_buster/src/kernel $ sudo make ARCH=arm64 mrproper $ sudo make ARCH=arm64 imx8_var_defconfig $ sudo make ARCH=arm64 menuconfig
Navigate the menu and select the desired kernel functionality
Exit the menu and answer "Yes" when asked "Do you wish to save your new configuration?"
$ sudo make ARCH=arm64 savedefconfig $ sudo cp arch/arm64/configs/imx8_var_defconfig arch/arm64/configs/imx8_var_defconfig.orig $ sudo cp defconfig arch/arm64/configs/imx8_var_defconfig
Building a new kernel configuration
Build the kernel image, dtb files and kernel modules
$ cd ~/var_mx8mm_dart_debian_buster $ sudo MACHINE=imx8mm-var-dart ./var_make_debian.sh -c kernel $ sudo MACHINE=imx8mm-var-dart ./var_make_debian.sh -c modules
Note: If you have modules newly added / removed, make sure you run the following command:
$ sudo MACHINE=imx8mm-var-dart ./var_make_debian.sh -c rtar
This will create a rootfs.tar.gz file that contains your new modules.
Deploy the kernel image, dtb files and kernel modules
Deploy Kernel, dtb via network
Updating Device tree to target
Transfer dtbs to target
On PC:
$ cd ~/var_mx8mm_dart_debian_buster $ scp output/*.dtb root@<yourboard-ip>:/boot/
Once prompted give root as password. <yourboard-ip> is ipaddress of your board.
Once transfer is done, follow below commands
On Target Console:
# sync;reboot
Note: If you just intend to do dtb, then only follow this section and reboot the target
Updating kernel Image to target
Transfer the output/Image.gz kernel image to target
On PC:
$ scp output/Image.gz root@<yourboard-ip>:/boot/
Once prompted give root as password. <yourboard-ip> is ipaddress of your board.
Once transfer is done, follow below commands
On Target Console:
# sync;reboot
