발열이 너무함.

armbian도 과거에 cli만 하다보니 발열이 착하다고 생각했는데

xfce 돌리니까 온도 60~70도는 기본으로 찍힌다. idle 인데 -_-

그래서 LTS 라고 저발열 보드가 나온게 아닌가 싶긴한데

아크릴 케이스 녹여먹을까봐 불안해서 쓸수가 없으니 그냥 봉인해야 할 듯..

차라리 armbian 기반에 해야하려나?

사용자 메뉴얼에 보면 install_to_emmc 치면 설치된다는데

정작 Orangepi3_2.1.0_ubuntu_focal_desktop_linux5.4.65.img 이미지를 이용해서 부팅해보면

해당 스크립트가 없다. debian도 아니고 ubuntu focal 이면 20.04인데

자기들이 릴리즈 하고 어디서 받으라는 말도 없는건 도대체 멀까?

3. Program Linux system into EMMC Flash chip through script
If you purchased the Orange Pi 3 development board with EMMC Flash chip, after booting the Linux system through the TF card, you can also burn the Linux system into EMMC Flash through the install_to_emmc script.
Enter the install_to_emmc command in the Linux terminal, and then enter y as prompted, and the Linux system will automatically be burned into EMMC Flash. After the programming is complete, turn off the power, remove the TF card, and then power on the Linux system in EMMC Flash automatically.

아래 스크립트가 나오는데 sd로 부팅하니 mmcblk1 : mmc1:0001 8GTF4R 7.28 GiB 라고 나오는걸 보면

/dev/mmcblk1이 emmc

/dev/mmcblk2 가 sdcard인것 같은데

스크립트 내용으로는 sdcard 변수가 emmc 경로여야 한다.

일단.. 메모리가 후달리겠지만 시도는 해볼까?

램 2GB에 eMMC 8GB 인걸로 기억하는데 SD 메모리 꽂고 스왑으로 쓰는게 나을까?

해당 이미지가 1GB 밖에 되지 않아, 4GB SD에 넣고 부팅을 하니 다음과 같은 화면 하나만 덜렁 나오고 끝이다.

아마도 eMMC에 복사하는 과정인 것 같은데, 여기까지 진행되면 전원 뽑고, SD 빼고 다시 켜면 끝

처음 켤때는 android 초기화 때문에 좀 오래 걸리지만 두번째 부팅에는 10초 정도? 걸린 것 같다.

youtube 앱(?)도 실은 firefox로 접속하게 하는거고 android 7이라 요즘 앱들은 설치하기 힘들듯.

오늘 출근해서 해보는데

debug uart 상관없이 둘다 9초는 지나야 kernel이 구동하고 그제서야 LED에 불이 들어온다.

아니.. run led도 아니고 power led 정도는 회로에서 바로 켜지게 해놔야 하는거 아냐?

 

아래 들어온게 power LED.

아니.. 말 그대로 파워만 들어오면 불이 들어와야지 이걸 uboot나 kernel 에서 on 하도록 하는 발상은 누가 한거냐.. -_-

armbian 은 uboot에서 안켜고 kernel 에서 켜고 앉았고

orange pi 3 이미지는 uboot 에서 켜주긴 한데

sd 를 꽂지 않으면 파워 led 자체가 불이 안들어와서 보드 고장난거 아냐!? 싶은 상황이 발생한다.

 

왼쪽 eMMC 부팅, 오른쪽 microSD 부팅 메시지

버전이나 좀 차이나고 로딩 속도에서 차이나지만 LED 켜지는 시간은 그게 그거..

중국제 SoC라 그런가 코덱에 allwinner든 amlogic이든 양쪽다 AVS가 들어있다.

대충 S905는 2016년 10월 이전에 출시 된 것 같고

[링크 : https://en.wikipedia.org/wiki/Amlogic]

 

H6는 2014년에 출시 된 것 같은데

[링크 : https://en.wikipedia.org/wiki/Allwinner_Technology]

 

벤치마크만 보면 오히려 늦게 나온 amlogic S905 보다 allwinner H6이 클럭빨로 우월한 성능을 보이는 느낌

그런데 클럭 대비라고 해도 S905X와 H6의 성능 차이가 너무 나는걸 보면 신뢰할 수 있나 싶을 정도..

armbian이 eMMC에 설치되어 있어서 보는데

480MHz에서 딱 달라붙어 있고 cpu 온도도 32도로 착하다

 

armbian-config를 실행하니

# armbian-config

 

orangepi-config 처럼 비슷하게 나온다.
