由于RV1103_Luckfox_Pico默认是使用sd卡烧录镜像的，但是给他焊了个spi nand flash，不用sd卡。
首先查看下flash信息
制作spi nand flash镜像的操作如下：
1） 使用linux系统，下载sdk
git clone https://gitee.com/LuckfoxTECH/luckfox-pico.git
2） 在目录luckfox-pico/project/cfg/BoardConfig_IPC下新建一个BoardConfig-SPI_NAND-Buildroot-RV1103_Luckfox_Pico_Pro-IPC.mk文件
将BoardConfig-SD_CARD-Buildroot-RV1103_Luckfox_Pico-IPC.mk的内容复制到BoardConfig-SPI_NAND-Buildroot-RV1103_Luckfox_Pico_Pro-IPC.mk中，然后修改下面五处

3）在目录luckfox-pico/sysdrv/source/kernel/arch/arm/boot/dts下复制一份rv1103g-luckfox-pico.dts并命名为rv1103g-luckfox-pico-pro.dts
cp rv1103g-luckfox-pico.dts rv1103g-luckfox-pico-pro.dts

4）编译镜像
# 选择参考板级
RV1103/luckfox-pico$ ./build.sh lunch
You're building on Linux
Lunch menu...pick the Luckfox Pico hardware version:
选择 Luckfox Pico 硬件版本:
[0] RV1103_Luckfox_Pico
[1] RV1103_Luckfox_Pico_Mini_A
[2] RV1103_Luckfox_Pico_Mini_B
[3] RV1103_Luckfox_Pico_Plus
[4] RV1106_Luckfox_Pico_Pro_Max
[5] RV1106_Luckfox_Pico_Ultra
[6] RV1106_Luckfox_Pico_Ultra_W
[7] custom

[build.sh:info] Running build_select_board succeeded.
# 一键自动编译
RV1103/luckfox-pico$ ./build.sh
要很久时间
5）使用SPI NAND Flash 烧录镜像
将luckfox-pico/output目录下的image文件夹全部复制到windows系统电脑上，然后打开SocToolKit工具
使用USB线将开发板连接上电脑
烧录完成后参考官方指导试一下串口调试，烧录的系统是buildroot
