nvidia jetson agx thor dev kit 설치 - USB boot

2026.07.24 기준

jetpack 7.2 / jetson linux 39.2

[링크 : https://developer.nvidia.com/embedded/jetpack/downloads]

usb 키보드 연결하고 esc 연타.

 

그나저나 먼가 익숙한(?) imx8mp 때의 부트로더라고 해야하나

UEFI 로더라고 해야하나 이게 보이네?!

boot manager 선택하고

 

NVIDIA Configuration 선택

 

Boot Configuration 선택

 

밑으로 내려가서(위로 한번 누르면 바로 내려감)

SOC Display Hand-Off Mode를 Auto 로 해주고 usb에 iso 구워서 켜면 그냥 pc 처럼 설치가 되나보다.

 

그냥 USB 꽂고 F11 눌러서 부팅 장치 선택하니(완전 PC네!)

USB 선택하고 엔터!

 

최후 통첩(?) 30초 기다려준다!

 

우분투 grub 는 깜박잊고(맨날 보던거라..) 그냥 넘어가버렸고

하위 선택에서 'Install on NVMe' 선택

 

많이 깔꺼니까 15분 정도 기다려! 라니!~ ㅋㅋ

 

엣! 잠시 자리 비운 사이에 리부팅 되었나 보다. 먼가 업데이트 하는 중

 

휴.. 조마조마했는데 다행이 먼가 뜬다!

불법촬영물 여부 검토

티스토리는 이거 대응한다고 업로드 하면 약간의 시간이 지난 후에 뜬다.

살색이 많은 이미지도 아닌데 왜 이래?

MCP2515 on rpi .. 2번째

벌써 3년전에 가볍게(?) 해봤었네..

또 까먹다니 이 기억력 어쩔.. ㅠㅠ

그때와 다른건.. 작년 부터 /boot/config.txt의 경로가 달라졌다는 정도?

loopback 설정. ifconfig 상으로는 별다른 티가 안난다

아무튼 loopback을 활성화 하고 ssh 로 창 두개 열어서 한쪽은 candump 실행해두고

다른 한쪽에서 cansend로 보내면 보내진다.

MCP2515 / TJA1050

 

D0695323C  라고 써있어서

이게 8 MHz 인지 16 MHz 인질 모르겠다. 검색해도 안나온다.

일단 두대를 보니 서로 다른게 써있어서 그냥 시리얼 번호라고 생각하는 중.

 

일단은 3.3V했는데 이러면 외부로 신호는 발생시키지 못할 듯.

 

예전에도 본건 데 전원이 잘못되었다고 개조를 해야 한다고 하는데

지금 다시 읽어보니 라즈베리 파이 gpio 가 3.3V 라서 아두이노와는 다르게 5V로 주면 라즈베리가 데미지 입게된다.

Because MCP2515 must be powered from 3,3V, because MCP2515 is directly connected to Pi GPIO and GPIO only accept 3,3V

[링크 : https://forums.raspberrypi.com/viewtopic.php?t=141052]

 

데이터 시트를 찾아보면

MCP2515는 2.7 V~5.5 V 면 되지만 SPI 도 Vdd 전압 따라가게 되면 흐음..

[링크 : https://ww1.microchip.com/downloads/en/DeviceDoc/MCP2515-Stand-Alone-CAN-Controller-with-SPI-20001801J.pdf]

 

CAN tranceiver칩은 4.75~5.25V 사이에 전압을 공급해야 한다.

[링크 : https://www.nxp.com/docs/en/data-sheet/TJA1050.pdf]

 

걍 속편하게 SPI 쪽만 레벨 시프터 쓸까? 개조가 나을까..

모델이 작은거라 그런가 94% 인데 33W라.. 좀 더 빡세게 굴려봐야하나 ㅋㅋ

nvidia MIG(multiple instance GPU) - thor

헛다리를 짚은것 같은데 메모리가 안나오는건 공유 메모리를 써서 인가.. 싶기도 하고?

아무튼 thor iGPU에서는 최대 2개로 나누어 쓸 수 있나 본데

gfx는 외부 출력 포트를 쓸수 있냐 없냐의 차이인것 같고

driver 버전은 이런데..

NVIDIA-SMI 580.00                 Driver Version: 580.00         CUDA Version: 13.0

jetpack 버전은 38.4 같다. 일단 위에서 JetPack 7.2GA/R39.2 라고 했으니 업데이드 해봐야하나?

nvidia jetson 아니고 nvidia thor

회사에 굴러 다니고 있어서 전기 먹여 봄

일단 blackwell 기반이니까 50 시리즈와 동급이란거구만

와우 금액 미쳤...

음.. 소비전력 안보이고, 메모리 사용량 미지원인가?

 

메모리 128GB

그나저나 내부적으로 말이 오락가락 했나 dmidecode  에서는 AGX Thor 라고 나온다.

익성전자 is3400 usb hid 모드

전화해서 물어보고 링크를 찾음

usb uart 모드로 접속해서 auto read 활성화하고

usb hid 모드로 켜면 된다.

 

모드는 별거(?) 아니고

그냥 커넥터를 옮겨서 USB to Serial에 연결해서 ISReadPro 프로그램으로 auto read 모드 설정하고

HID keyBoard에 연결하면 된다고 하는데. 선 한번 끊어먹고 의기소침해져서 일단 hid 모드는 언젠가로 미뤄야지 ㅋㅋ

여기서 먼저 활성화 해주고

 

여기서 카드 종류 별로 활성화 하면되는데

가장 만만한건.. 125khz 처럼 작동하는 iso14443a - uid 모드가 아닐까 싶다.

따라해보는데 안되서 일단 귀찮아 패스

"IS-3400-V1.9A" 로 읽히는데 막상 auto read 하면 응답이 없는걸 봐서는 버전 영향을 받기도 하는 듯?

blender 먼가 숨기기 단축키

shift - alt - Z (show overlays)

 

 

ctrl - space (오른쪽 메뉴 숨겨짐 - maximize area)

 

 

ctrl - alt - space (창모드 전체화면 - focus mode)

 

 

 

window - new window 하고

새로운 창에서(오브젝트는 원래 창과 공유됨)

focus mode + overlay off 하면 가장 간단하게 구현이 가능할 듯 하다.

blender quarternion

여기 메뉴에서 XYZ Euler가 기본인데 이걸 클릭하면

 

아래와 같이 rotation이 XYZ 에서 WXYZ로 변경된다.

 

근데 어떻게 써야할지, 어떻게 이해해야 할 진 모르겠음..
