【XR806开发板试用】从零开始（持更。。）

一般开发流程和可能遇到的问题

开发环境准备
请参考https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/quickstart-lite-env-prepare.md
代码下载
`
mkdir xr806_openharmony
cd xr806_openharmony
repo init -u ssh://git@gitee.com/openharmony-sig/manifest.git -b OpenHarmony_1.0.1_release --no-repo-verify -m devboard_xr806.xml
repo sync -c
repo forall -c 'git lfs pull'
`

如果下载进度卡在某一个x%不动，需要修改devboard_xr806.xml文件
`
cd xr806_openharmony/.repo/manifests
vim devboard_xr806.xml

删除下面两行：
<project name="devboard_device_allwinner_xr806" path="device/xradio" revision="master" remote="sig"/>
<project name="devboard_vendor_allwinner_xr806" path="vendor/xradio" revision="master" remote="sig"/>
`
之后，继续repo sync -c，下载完毕后，单独下载上面两个项目
`
cd xr806_openharmony/device/
git clone https://gitee.com/moldy-potat... xradio
cd xr806_openharmony/vendor/
git clone https://gitee.com/moldy-potat... xradio
`
即可顺利完成代码下载。

环境配置
参考https://gitee.com/openharmony...
设置编译工具链（一般默认即可）
vim device/xradio/xr806/liteos_m/config.gni
`
\# Compiler prefix.
board_toolchain_prefix = "~/tools/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-"

\# Compiler type, "gcc" or "clang".
board_toolchain_type = "gcc"
`

vim device/xradio/xr806/xr_skylark/gcc.mk
`
\# ----------------------------------------------------------------------------# cross compiler
\# ----------------------------------------------------------------------------
CC_DIR := ~/tools/gcc-arm-none-eabi-10-2020-q4-major/bin
CC_PREFIX := $(CC_DIR)/arm-none-eabi-
`

对代码工程进行配置
（截图中文件夹名称为xr806_test，根据实际自己调整）

cd device/xradio/xr806/xr_skylark
cp project/demo/audio_demo/gcc/defconfig .config

make menuconfig
（不需要更改，exit回车YES退出即可）

如果报错

执行sudo apt-get install libncurses5-dev

make build_clean

make lib -j
首次编译一次即可

cd -
返回Harmony根目录

hb set
选择wifi_skylark

hb build -f
编译

在hb build -f的过程中，如果有出现缺少某些文件的报错，可以直接从openharmony项目中将缺少的文件目录copy过来。

在hb build -f的过程中，如果出现以下错误，可以vim main.c删掉<200b>。

固件烧录

将device/xradio/xr806/xr_skylark/out/xr_system.img生成的固件，放到烧录工具device/xradio/xr806/xr_skylark/tools/phoenixMC_xxxx.exe中，修改烧录速率为3000000，“设置”勾选“硬件复位烧写模式”和“烧写后重启”。之后选择相应的串口，点击固件升级，即可完成固件烧录。

串口调试
使用友善串口调试助手（下载地址：http://alithon.com/downloads）查看输出并进行调试。

多种功能程序实现

先点个灯
在device/xradio/xr806/ohosdemo中新建一个light文件夹

cd light

static OS_Thread_t g_main_thread;

#define GPIO_ID_PA21 21

void light_biling(void){
  while (1) {
    IoTGpioSetOutputVal(GPIO_ID_PA21, 1);
    OS_MSleep(500);
    IoTGpioSetOutputVal(GPIO_ID_PA21, 0);
    OS_MSleep(500);
  }
}

static void MainThread(void *arg)                                               
{
  printf("LED test start\r\n");
  IoTGpioInit(GPIO_ID_PA21);
  IoTGpioSetDir(GPIO_ID_PA21, IOT_GPIO_DIR_OUT);
  light_biling();
}

void LEDMain(void)
{
  printf("LED Test Start\n");
  if (OS_ThreadCreate(&g_main_thread, "MainThread", MainThread, NULL, OS_THREAD_PRIO_APP, 4 * 1024) != OS_OK) {
    printf("[ERR] Create MainThread Failed\n");
  }
}

SYS_RUN(LEDMain);
