OPIでFedora22のメモ

投稿日:

loborisさんがリリースしている、Fedora22 のMinimal がどんなものテスト。

以下、備忘録です。Cで、GPIO ピンで光らせる部分まで確認。

 

・Fedora22_Minimal.img をsdcard に dd。要注意で。

$ sudo dd bs=1m if=./Fedora22_Minimal.img of=/dev/rdisk3

・BOOT パーティションの中は、orange pi pc の用途にあったものにリネーム。

[junkhack@OrangePi ~]$ ll /media/boot/
合計 10695
-rwxr-xr-x 1 root root    35724 10月 13 14:08 script.bin
-rwxr-xr-x 1 root root 10915616 10月 13 14:08 uImage

 

・SDCard 挿入、起動

・DHCP で起動するので、IP を固定に。以下のようになじみのあるeth0 に名前変更。

[root@opi 13:35:56 network-scripts]# ll ifcfg-*
-rw-r--r-- 1 root root 364 Jan  1  1970 ifcfg-LoBoInternet
-rw-r--r-- 1 root root 389 Dec 19 13:15 ifcfg-eth0
-rw-r--r-- 1 root root 254 Apr  9  2015 ifcfg-lo
[root@opi 13:36:06 network-scripts]# 

 

・中を変更

[root@opi 13:36:07 network-scripts]# cat ifcfg-eth0 
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=c0a09f2a-3229-4901-9689-7deb7e356848
DEVICE=eth0
ONBOOT=yes
DOMAIN=junkhack
IPADDR=192.168.1.42
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=192.168.1.17
DNS2=192.168.1.1
[root@opi 13:36:23 network-scripts]# 

 

・root のプロンプトを変更。好みで。

[root@opi 13:35:08 ~]# tail -n 3 .bash_profile 
PS1="[\u@opi \t \W]# "
export LANG=C

[root@opi 13:35:16 ~]# 

 

・タイムゾーン設定

[root@opi 13:34:18 ~]# timedatectl set-timezone Asia/Tokyo

・後方の空きパーティション拡大。スクリプトが同梱されているので。ない場合は、git にあるので参照。

[root@opi 13:37:46 ~]# find / -name fs_resize
/usr/local/bin/fs_resize
[root@opi 13:37:59 ~]# 

[root@opi 13:39:25 ~]# fs_resize

 

リブート

・cpu周波数のツールを入れ、ポリシーを見てみる。interactiveのようです。

[root@opi 13:43:15 ~]# dnf install cpufrequtils

[root@opi 13:51:19 ~]# cpupower frequency-info
analyzing CPU 0:
  driver: cpufreq-sunxi
  CPUs which run at the same hardware frequency: 0 1 2 3
  CPUs which need to have their frequency coordinated by software: 0 1 2 3
  maximum transition latency: 2.00 ms.
  hardware limits: 480 MHz - 1.54 GHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, interactive, performance
  current policy: frequency should be within 480 MHz and 1.54 GHz.
                  The governor "interactive"★ may decide which speed to use
                  within this range.
  current CPU frequency is 480 MHz (asserted by call to hardware).
  cpufreq stats: 60.0 MHz:0.00%, 120 MHz:0.00%, 240 MHz:0.00%, 312 MHz:0.00%, 408 MHz:0.00%, 480 MHz:96.37%, 504 MHz:0.00%, 600 MHz:0.00%, 648 MHz:0.00%, 720 MHz:0.00%, 816 MHz:0.01%, 912 MHz:0.00%, 1.01 GHz:0.95%, 1.10 GHz:0.06%, 1.20 GHz:0.21%, 1.34 GHz:0.17%, 1.44 GHz:0.01%, 1.54 GHz:2.21%  (173)
[root@opi 13:51:22 ~]# 

 

参考

http://oneofis05users.seesaa.net/article/288446337.html

    ■ Interactive

    より速いondemandを、ということで考案された。CPUがアイドル状態から

    抜けるとサンプリングを増やして追従を上げる。反応はondemandより良いが、

    最大クロックに上げるまでには間を取る。マルチタスクで忙しい仕事とゆっくり

    した仕事が交互にあっても、最大最小に切り替え時に一気に上下せず少し間を取って、

    中間のクロックを取る。パフォーマンス的にはondemandより良い。

    画面オンで早くトップスピードに上げるので、画面オンの時間が短く、それを

    繰り返すような使用法ではバッテリー消費が多くなる。

 

・kernel をあげてみる。上げる前は以下。

・消してしまってスクリプト上でチェックしているようで、ダミーを作成

[root@opi 14:21:02 src]# echo > /boot/uImage_OPI-2

・tar も入ってなかったのでいれておく。

[root@opi 14:25:05 src]# dnf install tar

・スクリプト実行

・基板上の電源LED の隣の緑LED が点灯、消灯

[root@opi 14:34:58 ~]# echo 1 > /sys/class/gpio_sw/standby_led/data
[root@opi 14:35:13 ~]# echo 0 > /sys/class/gpio_sw/standby_led/data

・WiringOP を入れる準備。c関連を面倒なのでグループインストール

All Done.

NOTE: To compile programs with wiringBP v2, you need to add:
    -lwiringPi
  to your compile line(s) To use the Gertboard, MaxDetect, etc.
  code (the devLib), you need to also add:
    -lwiringPiDev
  to your compile line(s).

・テストソース

[root@opi 14:54:54 gpio]# cat blink.c 
#include <wiringPi.h>

// Define GPIO Pin number wPi
#define LED 16
// delay 1 = 2msec
#define MSEC 500
// blink count 100 = 1sec
#define LOOP 100

// Main function
int main(void) {
        int i;

        // Initialize WiringPi
        wiringPiSetup ();

        // Set GPIO pin to output mode
        pinMode(LED, OUTPUT);

        // Repeat LED blinking 10 times
        for(i=0; i<LOOP; i++){
                digitalWrite(LED, LOW);
                delay(MSEC);
                digitalWrite(LED, HIGH);
                delay(MSEC);
        }

        // Turn off LED
        digitalWrite(LED, LOW);

        return 0;
}
