fsbl이 웬지 arm 에서 작동하는 느낌인데
ps가 먼저 살아나고
ps에서 pl을 초기화 하는 컨셉인 듯
그래서 ps만 쓸수는 있어도 fsbl등이 없이 pl만은 못 쓸지도 모르겠다
(아니 그러라고 만든 제품이 아니잖...)
일단은 부팅시간 측면에서는
ps기동하고
uboot 구동하고(키입력 없앤다 하더라도)
pl 초기화 하고(bit파일 읽는시간, 적재하는 시간 소요)
커널 로딩, 리눅스 기동
이라는 절차가 필요한데
리눅스 기동이 빠르게 필요하다면
리눅스 이후에 sysfs를 통해 pl을 초기화 해도 되지만
그러기엔 너무 전체 초기구동 시간이 너무 오래걸린다.
가능할진 모르겠지만
부트로더 개조해서 2 cpu 니까
smp가 아닌 amp로 기동해서
cpu0은 리눅스로 쓰고
cpu1은 pl 초기화 하는데 쓰면 좀 단축가능하려나?

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..

문득.. JTAG은 표준인데 왜 업체별로 다르지? 라는 생각에 검색하다 보니
공용으로 쓸 수 있는진 모르겠지만
openOCD를 이용하면 viviado 등이 없어도 FPGA에 쓸 수 있다고 하는걸 봐서는
openOCD가 각종 jtag를 지원한다고 보는게 맞을 듯.

The JTAG port supports a wide range of voltages, as it is connected to a couple of voltage translators (74LVC2T45). This makes the uniJTAG even more universal, as you can use it together with any JTAG�able device, running at 1.2V to 5.5V. The IO header can be used as 8 single controllable IO�s, or it can be used as a full standard UART port. With a jumper you can chose whether the IO�s should be at a 5V level, or a 3.3V level. The board has also an onboard EEProm for storing the FT2232 configurations, so the uniJTAG is a plug and play solution, and it automatically enumerates as a JTAG and a Serial device. |

새로 생성하지 않고 getImageData로 받은건 이상하게 편집이 안되는 느낌이라..
그냥 높이 1짜리로 새롭게 만들어서, 가장 위에 한줄 넣는게 무난한 듯.

| 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. root@OrangePi:~# install_to_emmc WARNING: EMMC WILL BE ERASED !, Continue (y/N)? y Erasing EMMC ...

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.
파일 전체 수정으로 emmc 라고 이름을 좀 바꿔주던가 헷갈리구루
