NuMaker-HMI-N9H30 固件下载（Linux）

前面 介绍了在 Windows 系统中使用 NuWriter 图形界面工具为 NuMaker-HMI-N9H30 开发板烧写固件程序的方法。对于 Linux 用户，虽然无法在 Linux 系统中运行 NuWriter 图形工具，不过我们可以使用命令行工具完成固件程序的下载。本文将以 Ubuntu 20.04 系统为例，演示如何安装 NUC970_NuWriter_CMD 命令行工具，并完成程序烧写。

编译安装​

安装依赖​

sudo apt install libusb-1.0-0-dev
sudo apt install autoconf automake automake-1.15

下载编译​

在 https://github.com/OpenNuvoton/NUC970_NuWriter_CMD 下载源代码，例如使用 git 克隆仓库。

git clone https://github.com/OpenNuvoton/NUC970_NuWriter_CMD.git

切换到 NUC970_NuWriter_CMD 目录

cd NUC970_NuWriter_CMD

配置并编译程序

./configure --prefix=$PWD/install
make

如果 make 失败，出现如下错误提示：

$ make
 cd . && /bin/bash /home/rudy/workspace/NUC970_NuWriter_CMD/missing automake-1.15 --foreign
configure.ac:6: error: version mismatch.  This is Automake 1.15.1,
configure.ac:6: but the definition used by this AM_INIT_AUTOMAKE
configure.ac:6: comes from Automake 1.15.  You should recreate
configure.ac:6: aclocal.m4 with aclocal and run automake again.
WARNING: 'automake-1.15' is probably too old.
         You should only need it if you modified 'Makefile.am' or
         'configure.ac' or m4 files included by 'configure.ac'.
         The 'automake' program is part of the GNU Automake package:
         [http://www.gnu.org/software/automake](http://www.gnu.org/software/automake)
         It also requires GNU Autoconf, GNU m4 and Perl in order to run:
         [http://www.gnu.org/software/autoconf](http://www.gnu.org/software/autoconf)
         [http://www.gnu.org/software/m4/](http://www.gnu.org/software/m4/)
         [http://www.perl.org/](http://www.perl.org/)
make: *** [Makefile:355：Makefile.in] 错误 1

那么需要执行下面命令，在重新 make 编译。

$ aclocal
$ autoreconf --force

安装​

编译完成后，执行下面命令将 nuwriter 安装到前面配置的指定目录

make install

添加 udev rule

sudo install -Dm644 99-nuvoton_isp.rules /etc/udev/rules.d/99-nuvoton_isp.rules

这样，nuwriter 命令行工具就安装成功了！可执行文件位于 install/bin/ 目录中。

命令参数​

执行 nuwriter -h 命令，查看 nuwriter 工具的选项参数，如下所示。
