Intel® Joule™ 550x 安裝ubuntu

作者：

前言

Intel 已經沒有維護了才拿出來玩...
物盡其用就把它當作小PC使用吧!

BIOS

joule-firmware-2017-06-02-1H3-public

[註]:千萬不要用最新的版本1J2,我當初刷下去後開機會卡在BIOS無法使用

OS

內存:
eMMC 8GB
內建Yocto作業系統
不建議刷掉此作業系統,
作業系統已經設好serial consle,
可以只接serial line直接連進機器
[註]:shutdown -r 0 //Yocto重開機指令




SDCard:


安裝ubuntu-18.04.3-server




安裝過程:


CPU是x86架構沒什麼困難


只要想辦法把OS塞進SDCard插進板子就沒問題了




我下載ubuntu-18.04.3-live-server-amd64.iso


直接使用PC將ubuntu安裝至SDCard


安裝完成順便安裝套件wireless-tools、wpa_supplicant、firmware-iwlwifi


機器插入SDCard,接上HDMI、鍵盤開機




為了方便使用serial line直接Debug,


設定serial consle,Grub及Ubuntu的sericl consle參照下方設定




設定完成後開機過程包含BIOS都可以透過serial去做操作


[註]:baud rate 115200

















Serial Consle





GRUB





https://c4691294.coding.me/Linux/Ubuntu-18-04配置serial-console/

我這邊找到serial port是掛在ttyS6

使用dmesg | grep tty

在Yocto跟Ubuntu比對查找

Systemd



下面似乎無效改用getty@.service





vim /etc/init.d/ttyS6.conf


# ttyS6 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/getty -L 115200 ttyS6 vt100




getty@.service



https://www.rogerirwin.co.nz/open-source/enabling-a-serial-port-console/


sudo nano /lib/systemd/system/serial-getty@.service
First we need to edit the serial-getty service to set the correct bard rate.

# Edit this line
ExecStart=-/sbin/agetty --keep-baud 115200,38400,9600 %I $TERM

# To This
ExecStart=-/sbin/agetty 115200 %I $TERM
Set this to the bard rate that you wish to use. This should be the same at the computer is using at the other end.

systemctl daemon-reload

# For a USB serial adaptor
systemctl enable serial-getty@ttyUSB0.service

# For a built in serial port /dev/ttyS6
systemctl enable serial-getty@ttyS6.service

Arduino Web Server DECodeURI












作者：
























  1.  架設一個簡單Web Server，以GET方式傳值發現傳入中文字收到的東西變得很不正常  原因是以GET傳值會進行ENCodeURI， 如 :   http://192.168.137.177/?test= 送出   ENCodeURI :   http://192.168.137.177/?test=%E9%80%81%E5%87%BA     2.   而 unicode utf-8是一種針對Unicode的可變長度字元編碼   在中文文字使用 3byte 表示   以 ” 送 ” 的 16 進位表示為 ” E9 80 81”   以 ” 出 ” 的 16 進位表示為 ” E5 87 BA”     URL 編碼會把一個字元以 16 進制表示轉成兩個字元，然後在其前面放置轉義字元 ("%") ，編碼完後 ” 送 ” 為 ” %E9%80%81” 、 " 出 ” 為 %E5%87%BA 。     3.   把 ’%’ 去除並 把兩個 ASCII 字元為一組如 ”E9”， 轉換成一個以 16 進位 表示 E9一個 字元。     ASCII 的 ’A’ 為 65 ， 16 進位 A 為 10 ， ASCII 的 ’0’ 為 48 ， 16 進位 0 為 0 ，   當讀到大寫英文字母進行數字計算以 ’A’ 為首減掉 ’A’ 的 65 加 10 ，讀到數字以 ’0’ 為首減掉 ’0’ 的 48 即可轉換成 16 進位表示。     因為兩個字元為一組把先讀到的字元轉成 16 進位做左移 4BIT 即乘於 16 ，與下一個字元轉成 16 進位相加，組合出一個 byte 存入字串內。      String newstring; for(int i=0;i<outputString.length();i++) {   if(outputString[i]=='%')   {     int temp;     char tempchar=0;     int test=16;     for(int j=1;j<3;j++)     {       if(outputString[i+j]>='A')       {         temp=(int)(outputString...
