编译

1.1环境准备

OS：Ubuntu 18.04 x64 或 Ubuntu 22.04 x64

安装hb

vm:~/$ python -m pip uninstall ohos-build # 卸载hb

vm:~/$ python -m pip install --user build/hb # 4.0及之后的版本和master安装hb 1.0.0版本

编译过程可以参考：

https://gitee.com/open-loongarch/wiki

1.2 拉取源码

vm:~/workspace/oh$ repo init -u git@gitee.com:open-loongarch/manifest.git -b ohos-v4.1 -m ls2k300-dev_v4.1.xml --no-repo-verify -v

vm:~/workspace/oh$ repo sync -c

vm:~/workspace/oh$ repo forall -c 'git lfs pull

1.3 编译

下载编译工具链

vm:~/workspace/oh$ ./build/prebuilts_download.sh

打补丁

vm:~/workspace/oh$ cd device/soc/loongson/

vm:~/workspace/oh/device/soc/loongson$ ./setup_toolchain.sh

vm:~/workspace/oh/device/soc/loongson$ ./patch.sh

vm:~/workspace/oh/device/soc/loongson$ cd -

编译支持通过hb 命令和使用build.sh 两种模式，用hb命令支持以菜单形式选择要的产品。

1.3.1使用hb 命令编译

通过hb set选择产品，完成之后通过hb build进行编译。

vm:~/workspace/oh$ hb set

OHOS Which os_level do you need? (Use arrow keys)

mini

❯ small

Standard

OHOS Which os_level do you need? small

OHOS Which product do you need? (Use arrow keys)

loongson

ls2k300_mini_dp_linux

❯ ls2k300_vanguard_pi_linux

vm:~/workspace/oh$ hb set

OHOS Which os_level do you need? small

OHOS Which product do you need? ls2k300_vanguard_pi_linux

vm:~/workspace/oh$ source ./set_env.sh

vm:~/workspace/oh$ hb build

在ubuntu22.04下，由于python版本的关系，直接执行hb set会报错，执行hb set出现的异常：

File "/home/ohos/.local/lib/python3.10/site-packages/prompt_toolkit/styles/from_dict.py", line 9,infrom collections import mapping

ImportError: cannot import name "Mapping" from "collections" ......

出现这种原因是因为Python3.10版本以后对requests库进行调整，collections中不能直接调用方法Mapping，MutableMapping。

解决方法：

编辑

~/.local/lib/python3.10/site-packages/prompt_toolkit/styles/from_dict.py

将文件中的

from collections import Mapping

修改为

from collections.abc import Mapping

1.3.2使用build.sh 脚本编译

这个方式需要先查看产品名称，但编译参数等配置可以比较灵活。

vm:~/workspace/oh$ source ./set_env.sh

vm:~/workspace/oh$ ./build.sh --product-name ls2k300_vanguard_pi_linux --ccache --gn-args build_xts=true --no-prebuilt-sdk

编译成功后会生成rootfs.img 和 rootfs.tar.gz 文件。

vm:~/workspace/oh$

cd out/ls2k300_vanguard_pi/ls2k300_vanguard_pi_linux/

vm:~/workspace/oh/out/ls2k300_vanguard_pi/ls2k300_vanguard_pi_linux$ ls rootfs.*

rootfs.img rootfs.tar.gz

1.4烧录系统镜像

将编译成功后生成的rootfs.img 烧录到板卡即可。烧录方法：

https://gitee.com/open-loongarch/docs-2k0300

见链接中的《2K0300先锋派/广东龙芯2K0300先锋派快速使用指南-v1.0.241010.pdf》

适配不同分辨率

代码默认适配的是 1024x768（7寸LCD），若想修改为800x480（4.3寸LCD）。

编辑

vendor/loongson/ls2k300_vanguard_pi_linux/graphic_config/product_graphic_lite_config.h

将文件中的

#define ATK_MD0700R_7_1024_600

// #define ATK_MD0430R_43_800_480

修改为

// #define ATK_MD0700R_7_1024_600

#define ATK_MD0430R_43_800_480

编辑

vendor/loongson/ls2k300_vanguard_pi_linux/hdf_config/input/input_config.hcs

将文件中的

inputAttr {

/* 0:touch 1:key 2:keyboard 3:mouse 4:button 5:crown 6:encoder */

inputType = 0;

solutionX = 1024;

solutionY = 600;

devName = "main_touch";

}

修改为

inputAttr {

/* 0:touch 1:key 2:keyboard 3:mouse 4:button 5:crown 6:encoder */

inputType = 0;

solutionX = 800;

solutionY = 480;

devName = "main_touch";

}

之后重新编译，将编译成功的roofs.img烧录到板卡中。而后在u-boot 中配置LCD 的分辨率为800x480。

2.1 配置分辨率

重启后按字母’m’, 进入u-boot 操作菜单

U-boot操作菜单，如下：

*** U-Boot Boot Menu ***

[1] System boot select
   [2] Update kernel
   [3] Update rootfs
   [4] Update u-boot
   [5] Update dtb
   [6] Update ALL
   [7] System install or recover
   [8] Video resolution select
   [9] Video rotation select
   [a] U-Boot console

Press UP/DOWN to move, ENTER to select, ESC/CTRL+C to quit

通过方向键移动选择 “[8] Video resolution select”，再按 “enter”键，进入下一级菜单：

*** U-Boot Boot Menu ***

[1] BOE BP101WX1-206 1280x800 60Hz

[2] ALIENTEK ATK-MD1010R 1280x800 60Hz

[3] ALIENTEK ATK-MD0430R 800x480 60Hz

[4] ALIENTEK ATK-MD0700R 1024x600 60Hz

[5] use board default panel

[6] Return

Press UP/DOWN to move, ENTER to select

通过方向键移动选择”ALIENTEK ATK-MD0430R 800x480 60Hz”，再按 “enter”键。之后输入reset重启板卡即可。
