All the previous articles focus on Ubuntu firmware. Interested readers can read it by themselves. Next, let's talk about how to compile and package Buildroot system firmware! Compiling Linux_ The SDK process is mostly the same as the Ubuntu system firmware described earlier. If the reader has ever compiled Linux_SDK, please read directly from the third part!
1, Construction of development environment
As we all know, the biggest headache of compilation is the host environment! Suppose I have boards from other chip manufacturers, each manufacturer's SDK uses a different compilation environment, and my Ubuntu host system has only one, what should I do?
Use Docker container!
According to the official wiki of Firefly, Ubuntu 18.04 is recommended. Let's build an Ubuntu 18.04 system under Docker!
1.1 host installation Docker
Copy this article I wrote earlier: Linux tools | building Docker container engine for Ubuntu
1.2 Docker installation Ubuntu 18.04
neutionwei@x:~$ sudo apt update neutionwei@x:~$ docker pull ubuntu:18.04
Switch Shell to Ubuntu 18.04:
neutionwei@x:~$ docker container run -p 8000:3000 -it ubuntu:18.04 /bin/bash root@32b7b9ddcaab:/# cat /etc/issue Ubuntu 18.04.6 LTS \n \l
1.3 common tools for Ubuntu 18.04 installation
root@32b7b9ddcaab:/# apt update root@32b7b9ddcaab:/# apt install byobu vim-gtk inetutils-ping net-tools wget cpio unzip rsync xz-utils
In the process, the region needs to be configured. Select Asia and Shanghai:
Configuring tzdata ------------------ Please select the geographic area in which you live. Subsequent configuration questions will narrow this down by presenting a list of cities, representing the time zones in which they are located. 1. Africa 3. Antarctica 5. Arctic 7. Atlantic 9. Indian 11. SystemV 13. Etc 2. America 4. Australia 6. Asia 8. Europe 10. Pacific 12. US Geographic area: 6 Please select the city or region corresponding to your time zone. 1. Aden 13. Barnaul 25.

2, Download Linux_SDK
Go to Firefly's official website and download it. The link is as follows:
https://www.t-firefly.com/doc/download/107.html
Click the place pointed in the following picture to download:
Download the latest version:
Because it is a certain degree of network disk, the download speed is...
Finally, the download is complete. First, use md5sum to verify:
neutionwei@x:~/Download/rk356x_linux_release_v1.2.0_20211019_split_dir$ ls md5sum.txt README_EN.txt README.txt rk356x_linux_release_v1.2.0_20211019_firefly_split.file0 rk356x_linux_release_v1.2.0_20211019_firefly_split.file1 rk356x_linux_release_v1.2.0_20211019_firefly_split.file2 rk356x_linux_release_v1.2.0_20211019_firefly_split.file3 rk356x_linux_release_v1.2.0_20211019_firefly_split.file4
neutionwei@x:~/Download/rk356x_linux_release_v1.2.0_20211019_split_dir$ md5sum *firefly_split* b633414d69240faa0c3bd755c255ede8 rk356x_linux_release_v1.2.0_20211019_firefly_split.file0 5cb1e2b63bbb4e3595c731038f6723fd rk356x_linux_release_v1.2.0_20211019_firefly_split.file1 e06c0f29fd5a870e0942139a1877a470 rk356x_linux_release_v1.2.0_20211019_firefly_split.file2 4e14fbf72ccbb9b87f81d83a256205b0 rk356x_linux_release_v1.2.0_20211019_firefly_split.file3 be8b003703b51e7220e52bb36439a357 rk356x_linux_release_v1.2.0_20211019_firefly_split.file4
Confirm with md5sum in the directory Txt file content is correct!
3, Compiling Linux_SDK
Install the necessary tools according to the official Firefly Wiki:
neutionwei@32b7b9ddcaab:/$ sudo apt-get install repo git ssh make gcc libssl-dev liblz4-tool \ expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support \ qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib \ unzip device-tree-compiler python-pip ncurses-dev python-pyelftools
Create a new directory for Ubuntu 18.04:
neutionwei@32b7b9ddcaab:/$ cd ~ neutionwei@32b7b9ddcaab:~$ mkdir project neutionwei@32b7b9ddcaab:~$ cd project/ neutionwei@32b7b9ddcaab:~/project$ pwd /home/neutionwei/project
The host uses the docker command to convert Linux_ Copy SDK to Ubuntu 18.04 under docker:
neutionwei@x:~/Download$ docker cp rk356x_linux_release_v1.2.0_20211019_split_dir 32b7b9ddcaab:/home/neutionwei/project
Unzip Linux_SDK:
neutionwei@32b7b9ddcaab:~/project$ cat rk356x_linux_release_v1.2.0_20211019_split_dir/*firefly_split* | tar -xzv
Configure the board model and select roc-rk3568-pc-builderoot mk:

Install bc command:
neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_20211019$ sudo apt install bc
Continue full compilation:
neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_20211019$ ./build.sh all
There are still errors:
./build.sh: line 874: /usr/bin/time: No such file or directory
ERROR: Running build_recovery failed!
ERROR: exit code 127 from line 874:

Install time command:
neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_20211019$ sudo apt install time
Continue full compilation:
neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_20211019$ ./build.sh all
If there are any missing commands in the process, continue the installation, and then continue the full compilation. The compilation process of builderoot is relatively long, because it involves the capture and of source code packages, and most of the source code package websites are not in China, so the capture speed is slow and even errors occur!
4, Package builderoot system firmware
Update package catalog soft link:
neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_20211019$ ./mkfirmware.sh
Package builderoot firmware:
neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_20211019$ ./build.sh updateimg
The firmware we packaged is in / home/neutionwei/project/rk356x_linux_release_20211019/rockdev/pack / directory.
Use the docker command on the host to copy the firmware back to the host and burn it:
neutionwei@x:~/Download$ docker cp 32b7b9ddcaab:/home/neutionwei/project/rk356x_linux_release_20211019/rockdev/pack/ROC-RK3568-PC-Buildroot-GPT-20211231-2044.img .
Write to the end
