20250520在全志H3平臺的Nano Pi NEO CORE開發板上運行Ubuntu Core16.04.3時跑通4G模塊EC20

1、h3-sd-friendlycore-xenial-4.14-armhf-20210618.img.gz 在WIN10下使用7-ZIP解壓縮/ubuntu20.04下使用tar
2、Win32DiskImager.exe 寫如32GB的TF卡。【以管理員身份運行】
3、TF卡如果已經做過會有3個磁盤分區，可以使用SD Card Formatter/SDCardFormatterv5_WinEN.zip格式化TF卡。DiskGenius可以嘗試。

制作好Ubuntu core22.04.3系統的IMG固件之后，還需要你編輯TF卡中的文件：
1、修改H:\eflasher.conf
autoStart=/mnt/sdcard/friendlycore-jammy
autoExit=true

2、root@NanoPi-NEO-Core:/opt# vi run-eflasher.sh?
root@NanoPi-NEO-Core:/opt# cat run-eflasher.sh?
poweroff

如果能夠直接編輯IMG固件就好了。到時候寫TF卡之后不需要每次都來編輯這兩個文件。

2025/5/20 14:51

緣起：公司將來要在全志H3平臺的Nano Pi NEO CORE開發板上運行Ubuntu Core16.04.3時使用移遠的4G模塊EC200A-CN。
但是先買的是EC20。現在也就是廢物利用了。
也許/可能在有訂單之前還不會確定最終用哪一款了！
友善之臂預編譯的IMG固件就已經適配好EC20了：h3-sd-friendlycore-xenial-4.14-armhf-20210618.img.gz
但是還是需要你在開發板上編譯quectel-CM命令行撥號程序。

How to use 4G Module on NanoPC-T4/zh

3 FriendlyCore下使用4G模塊EC20
3.1 第0步：將SIM卡插入到EC20中

3.2 第1步：在開發板上編譯quectel-CM命令行撥號程序
輸入以下命令，編譯并安裝quectel-CM到 /usr/bin/ 目錄：
git clone https://github.com/friendlyarm/quectel-cm.git
cd quectel-cm/
make
cp quectel-CM /usr/bin/

【不用做】3.3 第2步：創建udhcpc script

3.4 第3步：開始4G撥號
輸入以下命令啟動撥號：
quectel-CM &

撥號成功，屏幕會輸出IP地址等信息，如下所示：
root@NanoPC-T4:~# quectel-CM &

3.5 測試4G連接
ping一個域名，看看DNS解析是否已經在工作了：

root@NanoPC-T4:~# ping www.baidu.com
