官网参考：
https://nuttx.apache.org/docs/latest/quickstart/compiling.html

1、board配置

nhf@nhf-VirtualBox:~/work/learn/nuttx/NUTTX/nuttx$ ./tools/configure.sh -L | grep samv71
  samv71-xult:nsh
  samv71-xult:netnsh
  samv71-xult:vnc
  samv71-xult:module
  samv71-xult:nxwm
  samv71-xult:vnxwm
  samv71-xult:knsh
  samv71-xult:mxtxplnd
  samv71-xult:mrf24j40-starhub
nhf@nhf-VirtualBox:~/work/learn/nuttx/NUTTX/nuttx$ ./tools/configure.sh -l samv71-xult:nsh
  ......
  mkkconfig in /home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/apps
  make[1]: 离开目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/apps”
  #
  # configuration written to .config
  #

2、外设配置

在这里插入图片描述
打开menuconfig

nhf@nhf-VirtualBox:~/work/learn/nuttx/NUTTX/nuttx$ make menuconfig

在这里插入图片描述

图中usb连接是串口usart1，所以使能usart1，作为调试口：
使能usart1外设
System Type —>SAMV7 Peripheral Selection -->USART 1
选择usart1外设作为console调试口：
Device Drivers —>Serial Driver Support -->Serial console
使能SD卡接口支持：
System Type -->SAMV7 Peripheral Selection -->High Speed Multimedia Card Interface (HSMCI)
使能文件系统自动挂载：
File System -->Auto-mounter
使能SD卡自动挂载：
Board Selection–>HSMCI0 automounter
使能根文件系统支持：
File Systems -->ROMFS system
使能根文件系统启动脚本支持：
Application Configuration -->NSH Library -->Scripting Support -->Support ROMFS start-up script
使能内置命令例程：
Application Configuration -->Examples
使能命令行历史：
Application Configuration -->System Libraries and NSH Add-Ones -->read() Support

基本配置完成。

3、编译

nhf@nhf-VirtualBox:~/work/learn/nuttx/NUTTX/nuttx$ make -j8
make[1]: 进入目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx”
make[1]: 进入目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/tools”
make[1]: 进入目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/tools”
make[1]: 进入目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/tools”
make[1]: 进入目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/tools”
make[1]: 离开目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/tools”
make[2]: 进入目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/boards”
make[1]: 离开目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/tools”

LD: nuttx
make[1]: 离开目录“/home/nhf/mnt/newdisk/work/learn/nuttx/NUTTX/nuttx/arch/arm/src”
CP: nuttx.bin

编译成功之后，生成 nuttx.bin，即可烧录至开发板中进行调试。

4、console

程序烧录完之后，打开串口终端工具，有如下打印信息，即编译并烧录成功：
