회사일을 Jetson Tx2관련일을 하게되어 이에 관련된 일을 간단히 정리하고자 한다.
그리고, 인터넷에 오픈된 것만 관련하여 간단히 서술한다.
현재 Ubuntu는 16.04LTS이며, 아래와 같이 Jetpack 3.3 설치를 하며, 설치 방법도 EVM의 영문 매뉴얼을 참조하면 어느정도 이해를 할수 있다.
- Jetson TX2 Jetpack 설치 정보
$ sudo apt update && sudo apt upgrade -y
아래의 부분은 Jetson TX2에서 진행을 했지만, 동작이 되지 않았다.
$ sudo ./jetson_clocks.sh $ cd ~/tegra_multimedia_api/samples/backend ./backend 1 ../../data/Video/sample_outdoor_car_1080p_10fps.h264 H264 --trt-deployfile ../../data/Model/GoogleNet_one_class/GoogleNet_modified_oneClass_halfHD.prototxt --trt-modelfile ../../data/Model/GoogleNet_one_class/GoogleNet_modified_oneClass_halfHD.caffemodel --trt-forcefp32 0 --trt-proc-interval 1 -fps 10

2. JetPack 설치 후 USB Device 정보
Jetson TX2의 Jetpack 3.3 설치 후 아래와 같이 USB의 설정확인하였으며, 간단히 정리해본다.
일반적인 USB 정보 알아두자.

- Host PC 확인 (JetsonTX2 USB 접속)
좀더 자세히 분석하여 알아 보면 다음과 같다.
Jetson TX2의 USB Device Mode 일경우 지원사항
- USB Mass Storage : USB CDC 관련 Manual 내용
- USB CDC-ACM : /dev/ttyACM0 으로 Serial로 쉽게 Login 가능
- USB CDC-RNDIS: USB를 통하여 Window의 RNDIS Ethernet 사용가능
- USB CDC-ether: USB CDC Ethernet이며 RNDIS와 같이 연동되는 것 같음
Window에서는 Network는 상위 CDC-RNDIS만 지원될 것라고 생각함
USB CDC-Network Adapters (Kernel Config 사항)
( Device Drivers - Network device support - USB Network Adapters)
CONFIG_USB_NET_CDCETHER
CONFIG_USB_NET_RNDIS_HOST
CONFIG_USB_NET_CDC_EEM
CONFIG_USB_NET_CDC_MBIM
USB CDC ACM (Kernel Config 사항)
( Device Drivers - USB support)
CONFIG_USB_ACM
**CDC-ACM은 Ethernet 기반의 Adapter가 아니므로 별도로 /dev/ttyACMx 존재하지만,
상위 Network Adapters들의 경우 별도의 /dev는 존재하지 않음 주의

WARNING: Each option in this kernel commandline gets higher preference over the same option from fastboot. In case of NFS booting, this script adds NFS booting related arguments, if -i option is omitted. -F --------- Flash server such as fastboot.bin. -G ------- Read partition and save image to file. -I ---------- initrd file. Null initrd is default. -K ---------- Kernel image file such as zImage or Image. -L ------ Bootloader such as cboot.bin or u-boot-dtb.bin. -M -------- MTS boot file such as mts_si. -N --------- i.e. :/my/exported/nfs/rootfs. -P -- Primary GPT start address + size of PPT + 1. -R ------ Sample rootfs directory. -S ------------ Rootfs size in bytes. Valid only for internal rootdev. KiB, MiB, GiB short hands are allowed, for example, 1GiB means 1024 * 1024 * 1024 bytes. -T -------- ITS file name. Valid only for u-boot. --no-flash ----------- perform all steps except physically flashing the board. This will create a system.img. --bup ---------------- Generate bootloader update payload(BUP). --multi-spec---------- Enable support for building multi-spec BUP. --clean-up------------ Clean up BUP buffer when multi-spec is enabled. --usb-instance -- Specify the USB instance to connect to; integer ID (e.g. 0, 1), bus/dev (e.g. 003/091), or USB port path (e.g. 3-14). The latter is best.
