htop graph style

htop 이 armbian 에서는 온도도 나오고 좋아 보이길래 어떻게 설정하나 찾아보는데

htop 홈페이지에서 cpu 그래프가.. 신기한게 보여서 빌드도 해보는데 안되서 좌절하다가

[링크 : https://htop.dev/screenshots.html]

[링크 : https://github.com/htop-dev/htop]

htop graph 로 검색해보니 먼가 걸려나온다.

Remember you can press space bar to change the meter style. That way you can get the graph display you want.
And by the way, graph display for Load average will not probably work what you expect. It's work-in-progress. Patches are welcome.

[링크 : https://github.com/hishamhm/htop/issues/440]

F2(setup) 에서 Meters에 하단에 보니 Space / Style!

아무튼 CPU와 같은 녀석들은 [Bar] 라고 되어있는데 이걸 space 누르면 스타일이 변경된다.

valgrind callgrind

valgrind는 일반적으로 메모리 누수를 찾는데 쓰지만

call graph라고 해야하나? call 관련 추적도 가능하다고 하니 다음에 돌려봐야겠다.

tool에 여러가지 있는데 cachegrind 정도만 찾아봤던 흔적이 있네..

openOCD와 jtag

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.

We decided to support both urJTAG and the well known OpenOCD out of the box.

MARVEL » fx FEROCEON CPU CORE
FPGA » fx Xilinx Spartan, Virtex or Altera Cyclone, Stratix
CPLD » fx Xilinx CoolRunner or Altera MAX

Technical details
The board itself is 5 by 5 cm with a USB B connector at one side and JTAG and IO headers at another.

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.

html canvas와 시간 그래프 흘리기

canvas에 먼가 그려져 있어야 테스트를 하니 일단 줄을 그리고

const canvas = document.getElementById("myCanvas");
const ctx = canvas.getContext("2d");

// Start a new Path
ctx.beginPath();
ctx.moveTo(0, 0);
ctx.lineTo(300, 150);

// Draw the Path
ctx.stroke();

[링크 : https://www.w3schools.com/jsref/canvas_lineto.asp]

여기서 나오는 waterfall display를 canvas로 간단하게 그려보려고 하니

[링크 : https://www.arc.id.au/Spectrogram.html]

간간히 아래와 같은 경고? 에러가 나지만 일단 무시하고 실행은 가능하니 나중에 찾아봐야 할 듯.

tt.html:27 Canvas2D: Multiple readback operations using getImageData are faster with the willReadFrequently attribute set to true. See: https://html.spec.whatwg.org/multipage/canvas.html#concept-canvas-will-read-frequently

[링크 : https://html.spec.whatwg.org/multipage/canvas.html#concept-canvas-will-read-frequently]

getImageData를 이용하여 좌상단으로 부터 가장 아래 1줄 빼고 복사하고

putImageData를 이용하여 복사한 그림을 위에 1줄 비우고 붙여넣는다.

결과적으로 가장 왼쪽 위 1픽셀은 남은채 나머지는 아래로 흘러내리는 애니메이션 완성!

<!DOCTYPE html>
<html>
<head>
</head>
<body>
    <canvas id="sepctrograph" height=500 width=1800></canvas>
    <script>
        function init_canvas()
        {
            canvas = document.getElementById("sepctrograph")
            ctx = canvas.getContext("2d");

            // Start a new Path
            ctx.beginPath();
            ctx.moveTo(0, 0);
            ctx.lineTo(300, 150);

            // Draw the Path
            ctx.stroke();
        }

        function flow_canvas()
        {
            console.log("ing");
            canvas = document.getElementById("sepctrograph")
            ctx = canvas.getContext("2d");
            imgObj = ctx.getImageData(0,0, canvas.width, canvas.height - 1);
            ctx.putImageData(imgObj, 0, 1); // next line draw
        }

        init_canvas();
        setInterval(flow_canvas, 1000);

    </script>
    </body>
</html>

+

새로 생성하지 않고 getImageData로 받은건 이상하게 편집이 안되는 느낌이라..

그냥 높이 1짜리로 새롭게 만들어서, 가장 위에 한줄 넣는게 무난한 듯.

const myImageData = ctx.createImageData(width, height);

차라리 armbian 기반에 해야하려나?

[링크 : https://forum.libreelec.tv/thread/25388-orange-pi-3-emmc-install/]

-------

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.

인터넷 찾아보니

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
