HiSpark Wi-Fi IoT小車上手之燒錄出廠樣例
作者：yukoyu
本篇帶給大家HiSpark Wi-Fi IoT智能小車套件上手之燒錄出廠樣例，希望對你有所幫助！
1.下載樣例代碼
①.gitee倉庫地址
https://gitee.com/hihope_iot/hispark-pegasus-smart-car.git
②.克隆代碼到本地
git clone https://gitee.com/hihope_iot/hispark-pegasus-smart-car.git
③.將樣例代碼拷貝到openharmony
目錄：hispark-pegasus-smart-car\智能循跡避障小車樣例代碼\robot_demo
拷貝到：openharmony\applications\sample\wifi-iot\app\
2.使能編譯IIC驅動
目錄：openharmony\device\hisilicon\hispark_pegasus\sdk_liteos\build\config\usr_config.mk。
找到這里
# CONFIG_FACTORY_TEST_SUPPORT is not set
# end of Factory Test Settings
#
# BSP Settings
#
CONFIG_I2C_SUPPORT=y 《《《打開編譯IIC驅動，改成這樣
# CONFIG_I2S_SUPPORT is not set
# CONFIG_SPI_SUPPORT is not set
# CONFIG_DMA_SUPPORT is not set
# CONFIG_SDIO_SUPPORT is not set
# CONFIG_SPI_DMA_SUPPORT is not set
# CONFIG_UART_DMA_SUPPORT is not set
CONFIG_PWM_SUPPORT=y
CONFIG_PWM_HOLD_AFTER_REBOOT=y
CONFIG_AT_SUPPORT=y
CONFIG_FILE_SYSTEM_SUPPORT=y
CONFIG_UART0_SUPPORT=y
CONFIG_UART1_SUPPORT=y
# CONFIG_UART2_SUPPORT is not set
# end of BSP Settings
3.把樣例加入編譯
目錄：openharmony3\applications\sample\wifi-iot\app\BUILD.gn。
import("http://build/lite/config/component/lite_component.gni")
lite_component("app") {
features = [
"robot_demo:robot_demo",
"robot_demo/ssd1306:oled_ssd1306",
]
}
注意：官方樣例使用說明 https://gitee.com/hihope_iot/hispark-pegasus-smart-car 里面的 BUILD.gn 未將 oled_ssd1306 加入編譯，不加入會報錯。
4.編譯樣例
①.設置編譯路徑
hb set
.(英文字符)
復制②.選擇wifiiot_hispark_pegasus
③.執行編譯
hb build -f
5.燒錄
①打開HiBurn燒錄工具
②. 選擇要燒錄的文件
點擊select fine
選擇該路徑：openharmony\out\hispark_pegasus\wifiiot_hispark_pegasus 下的Hi3861_loader_signed.bin和Hi3861_wifiiot_app_allinone.bin
復制
③.勾選上 Auto burn
④.燒錄
點擊Connect⑤.開發板復位
開始燒錄。
⑥.燒錄完成，點擊disconnect按鈕
6.測試結果
測試成功!
7.報錯解決
①.未使能驅動編譯
報錯提示：
[OHOS ERROR] riscv32-unknown-elf-ld: ohos/libs/libhal_iothardware.a(libhal_iothardware.hal_iot_i2c.o): in function `IoTI2cInit':
[OHOS ERROR] hal_iot_i2c.c:(.text.IoTI2cInit+0x10): undefined reference to `hi_i2c_init'

]
}
③.HiSpark Wi-Fi IoT開發板上電沒反應
可能原因：使用了雙頭Type-C數據線供電，導致無法供電，因為開發板沒有受電端誘騙芯片。
