``` ## 获取代码通过执行如下几条命令获取基础代码： ``` repo init -u git@gitee.com:oh-mini/manifest.git -b ohla-v502r -m default_ohla_mini.xml --no-repo-verify repo sync -c -j8 repo forall -c 'git lfs pull' ./build/prebuilts_download.sh ``` 获取上述代码和默认的编译构建工具之后，可以尝试编译示例项目。 ## 编译代码安装 OpenHarmony 编译工具 ``` python3 -m pip install --user build/hb ``` 验证 hb 安装成功 ``` export PATH=~/.local/bin:$PATH hb help ``` 以编译L0的wifiiot_hispark_pegasus为例，在代码根目录下执行： ``` hb set ``` 选择 mini，再在子菜单下选择 hisilicon/wifiiot_hispark_pegasus。再执行： ``` hb build ``` 或者执行： ``` ./build.sh --product-name wifiiot_hispark_pegasus --no-prebuilt-sdk ``` 即可编译指定的项目。 ## 编译代码(ls2k300) 以编译L0的ls2k300_mini_dp为例，在代码根目录下执行： ``` hb set ``` 选择 mini，再在子菜单下选择 loongson/ls2k300_mini_dp。再执行： ``` hb build ``` 或者执行： ``` hb build -f -b debug --gn-args build_xts=True ``` 即可编译指定的项目。 ``` [OHOS INFO] -------------------------------------------- [OHOS INFO] ccache summary: [OHOS INFO] ccache version: 4.5.1 [OHOS INFO] cache hit (direct): 0 [OHOS INFO] cache hit (preprocessed): 13 [OHOS INFO] cache miss: 3 [OHOS INFO] hit rate: 81.25% [OHOS INFO] miss rate: 18.75% [OHOS INFO] Cache size (GB): 4.94 / 100.00 (4.94 %) [OHOS INFO] --------------------------------------------- [OHOS INFO] end hpm command [OHOS INFO] start run hpm command [OHOS INFO] end hpm command [OHOS INFO] start run hpm command [OHOS INFO] unrecognized ninja log format, we need # ninja log v5 [OHOS INFO] [OHOS INFO] end hpm command [OHOS INFO] start run hpm command [OHOS INFO] c targets overlap rate statistics [OHOS INFO] subsystem files NO. percentage builds NO. percentage overlap rate [OHOS INFO] commonlibrary 2 0.3% 2 0.3% 1.00 [OHOS INFO] hiviewdfx 12 1.8% 12 1.8% 1.00 [OHOS INFO] kernel 50 7.4% 50 7.4% 1.00 [OHOS INFO] security 123 18.1% 123 18.1% 1.00 [OHOS INFO] startup 26 3.8% 26 3.8% 1.00 [OHOS INFO] systemabilitymgr 15 2.2% 15 2.2% 1.00 [OHOS INFO] test 51 7.5% 51 7.5% 1.00 [OHOS INFO] thirdparty 394 58.1% 394 58.1% 1.00 [OHOS INFO] xts 51 7.5% 51 7.5% 1.00 [OHOS INFO] [OHOS INFO] c overall build overlap rate: 1.00 [OHOS INFO] [OHOS INFO] [OHOS INFO] end hpm command [OHOS INFO] build success [OHOS INFO] Cost Time: 0:00:07 ``` ## 运行 ``` => tftp 0x9000000001000000 OHOS_Image.bin Speed: 1000, full duplex TFTP timeout (1 ms) too low, set min = 1000 ms Using ethernet@0x16020000 device TFTP from server 192.168.1.2; our IP address is 192.168.1.20 Filename 'OHOS_Image.bin'.
