1 Configuring kernel command line parameters
1.1 eMMC Boot
Here are the steps:
Make an eflahser bootable SD card (use the firmware file starting with rk3xxxx-eflasher-),
Insert the SD card into your computer, go to the SD card's OS-related directory, and edit the file parameter.txt, which is a text file containing command-line parameters,
Then boot from the SD card and burn the system to the eMMC.
1.2 SD Boot
To modify the command line parameters of the SD card, you need to repackage the SD card image file,
you can use the sd-fuse script we provide to assist packaging, here take rk3568 as an example,
other CPUs also have the corresponding sd-fuse repository, replace the word rk3568 with other cpu models:
git clone https://github.com/friendlyarm/sd-fuse_rk3568.git cd sd-fuse_rk3568 wget --no-proxy http://112.124.9.243/dvdfiles/RK3568/images-for-eflasher/debian-buster-desktop-arm64-images.tgz tar xvzf debian-buster-desktop-arm64-images.tgz vim debian-buster-desktop-arm64/parameter.txt # Edit command-line parameters ./mk-sd-image.sh debian-buster-desktop-arm64 # Repackage sd image file
