wget https://raw.githubusercontent.com/friendlyarm/sd-fuse_rk3328/kernel-5.15.y/tools/resource_tool && chmod 755 resource_tool
wget https://raw.githubusercontent.com/friendlyarm/sd-fuse_rk3328/kernel-5.15.y/prebuilt/boot/logo.bmp
wget https://raw.githubusercontent.com/friendlyarm/sd-fuse_rk3328/kernel-5.15.y/prebuilt/boot/logo_kernel.bmp
./mkkrnlimg arch/arm64/boot/Image kernel.img
./resource_tool --dtbname arch/arm64/boot/dts/rockchip/rk3328-nanopi*-rev*.dtb logo.bmp logo_kernel.bmp

After the compilation, the following files will be generated:

kernel.img resource.img The kernel modules are located in the out-modules directory

Run your build:
Please refre to #Running the build

This section applies to the following operating systems:

buildroot friendlycore-focal-arm64 friendlywrt21 friendlywrt21-docker friendlywrt22 friendlywrt22-docker friendlycore-lite-focal-arm64 debian-bullseye-core-arm64

Clone the repository to your local drive then build: 

git clone https://github.com/friendlyarm/rkbin --single-branch --depth 1 -b friendlyelec

export PATH=/opt/FriendlyARM/toolchain/11.3-aarch64/bin/:$PATH
cd uboot-rockchip/
./make.sh nanopi_r2

After the compilation, the following files will be generated:

2.1 Install to target board
2.1.1 GPT partition

This section applies to the following operating systems:

buildroot friendlycore-focal-arm64 friendlywrt21 friendlywrt21-docker friendlywrt22 friendlywrt22-docker friendlycore-lite-focal-arm64 debian-bullseye-core-arm64

RK3328 uses GPT partitions by default, you can use the dd command, but be careful to choose the right output device:

  • The SD/TF Card device node: /dev/mmcblk0
  • The eMMC device node: /dev/mmcblk2

The following is an example of how to update the kernel to eMMC:
Use the 'parted' command to view the partition layout: 

parted /dev/mmcblk2 print

Sample outputs: 

Model: MMC BJTD4R (sd/mmc)
Disk /dev/mmcblk2: 31.3GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
 
Number  Start   End     Size    File system  Name      Flags
 1      8389kB  12.6MB  4194kB               uboot
 2      12.6MB  16.8MB  4194kB               trust
 3      16.8MB  21.0MB  4194kB               misc
 4      21.0MB  25.2MB  4194kB               dtbo
 5      25.2MB  41.9MB  16.8MB               resource
 6      41.9MB  83.9MB  41.9MB               kernel
 7      83.9MB  134MB   50.3MB               boot
 8      134MB   2500MB  2366MB  ext4         rootfs
 9      2500MB  31.3GB  28.8GB  ext4         userdata

as shown above, the resource partition is located at 5 and the kernel partition is located at 6. Use the dd command to write the resource.img and kernel.img files to these partitions, the commands are as follows: 

dd if=resource.img of=/dev/mmcblk2p5 bs=1M
dd if=kernel.img of=/dev/mmcblk2p6 bs=1M

If you want to update u-boot: 

dd if=boot.img of=/dev/mmcblk2p1 bs=1M

To update new driver modules, copy the newly compiled driver modules to the appropriate directory under /lib/modules.

2.2 Packaging and creating an SD image

To create a new OS image file, you need to use the "sd-fuse" packaging tool.

"sd-fuse" is a collection of scripts that can be used to create bootable SD card images for FriendlyElec boards. Its main features include:

  • Creation of root filesystem images from a directory
  • Building of bootable SD card images
  • Simple compilation of kernel, U-Boot, and third-party drivers

Please click on the following link to find out more:

Kernel version Packaging Tool
linux v4.19.y sd-fuse_rk3328/kernel-4.19
linux v5.15.y sd-fuse_rk3328/kernel-5.15.y
2.3 USB flashing
2.3.1 Linux

To flash U-Boot and kernel using the "upgrade_tool" tool, please use the following command: 

sudo upgrade_tool ul MiniLoaderAll.bin
sudo upgrade_tool di -p parameter.txt
sudo upgrade_tool di uboot uboot.img
sudo upgrade_tool di trust trust.img
sudo upgrade_tool di resource resource.img
sudo upgrade_tool di kernel kernel.img
sudo upgrade_tool RD

Note: "upgrade_tool" is a command-line tool provided by Rockchip for Linux operating systems (Linux_Upgrade_Tool).
