Jetson TX2 Jetpack3.3 설치 및 USB Device 관련사항

1. Jetson Tx2 Jetpack 설치 

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 
현재 나의 경우는 JetPack L4T를 설치를 Force Recovery Mode를 이용하여 최종으로 설치한다음 아래와 같이 update와 upgrade를 진행했다.

$ 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)
Jetpack 3.3 설치 후 아래와 같이 USB를 확인을 해보면 Nvidia 관련사항을 확인가능
좀더 자세히 분석하여 알아 보면 다음과 같다.

Jetson TX2의 USB Device Mode 일경우 지원사항
  1. USB Mass Storage :  USB CDC 관련 Manual 내용 
  2. USB CDC-ACM :  /dev/ttyACM0 으로 Serial로 쉽게 Login 가능 
  3. USB CDC-RNDIS:  USB를 통하여 Window의 RNDIS Ethernet 사용가능 
  4. USB CDC-ether:  USB CDC Ethernet이며 RNDIS와 같이 연동되는 것 같음  
결론적으로 USB Ethernet이 두개 지원가능하며, Serial도 지원가능 및 Mass Storage도 지원
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

  • Jetson TX2의 USB-ACM Interface 
Jetson Manual을 읽어보면, 기본으로 nvidia/nvidia 로 id/pw로 제공을 하며, 두번째 id와 pw는 ubuntu/ubuntu를 제공해준다.


$ ls /dev/ttyACM0    // USB ACM  Interface 확인 
/dev/ttyACM0
$ minicom -s    // JetsonTx2 접속  nvidia:nvidia 


2.1 Jetson의 USB Ethernet 통신 설정 

Host PC와 Jetson Tx2 USB의 설정을하면 USB를 통하여 Internet 통신이 가능하다.
이를 이용하여 SSH 와 SFTP 및 추후 GDB까지 기능확장이 가능하다.
이 관련 Manual은 Mass Storage의 영문 Manual을 참조하자.

  • Host PC의 USB Host 의 Network 설정 
나의 경우 Host PC 아래와 같이  두 개의 USB Interface가 잡히며, 이를 설정해주자.
이 관련내용은 Mass Storage의 영문 매뉴얼을 참조하자.

usb0 직접 설정 or DHCP 설정

$ sudo ifconfig usb0 192.168.55.2 netmask 255.255.255.0 up
or
$ udhcpc -i usb0   // DHCP Client로 설정 

network 환경설정

$ sudo vi /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto usb0
iface usb0 inet static
netmask 255.255.255.0
address 192.168.55.2


상위와 같이 설정후  Host PC에서 Jetson(192.168.55.2)로 접속가능.(SSH/SFTP/NFS)

$ ssh nvidia@192.168.55.2   // ID: ubuntu 가능 
$ sftp nvidia@192.168.55.2  // ID: ubuntu 가능 

  • Jetson 의 NFS지원 
아래와 같이 Kernel에서 NFS는 지원이 되지만, /sbin/mount의 NFS가 지원이 되지 않아 별도의 package 설치
 
$ cat /proc/filesystems | grep nfs  // Kernel의 NFS지원확인 
$ sudo apt-get install nfs-common   // mount nfs 지원 
$/sbin/mount  // mount 명령어 nfs 지원확인 
mountall                mount.ecryptfs_private  mount.lowntfs-3g        mount.nfs4              mount.ntfs-3g
mount.ecryptfs          mount.fuse              mount.nfs               mount.ntfs  

Host PC의 NFS Server 설정 후 아래와 같이 테스트

$ mount -t nfs -o nolock 192.168.5.3:/home/jhlee/test /home/nvidia/test

3.  Flash Jetson TX2

Host PC에서 USB를 통해 손쉽게 Flash하며, Backup 도 가능하기 때문에 관련 Command를 소개한다.


  • USB Force Recovery Mode



  • flash.sh 기본사용법 
Host PC와 Jetson의 microUSB 과 연결하여 USB를 통하여 Image를 Write or Read 할 수 있는 기능이다.





  • Host PC USB 연결확인 
만약 문제가 있다면, 상위 USB Force Recovery Mode로 진입하자.

$ lsusb  // Host 에서 USB 로 Jetson TX2 연결 후 Connection 확인
.....
Bus 001 Device 036: ID 0955:7020 NVidia Corp. 

  • Image Flash 방법  (USB 연결확인 후)
$  cd jetsonTX2/64_TX2/Linux_for_Tegra // JetPack 3.3 설치 위치  
$ sudo ./flash.sh  jetson-tx2 mmcblk0p1// For Jetson TX2 


  • Image Backup 및 Flash 방법 
$ sudo ./flash.sh -r -k APP -G clone.img jetson-tx2 mmcblk0p1    //기존에 사용하던 Image Backup
$ ls
clone.img  clone.img.raw
$ sudo cp clone.img.raw bootloader/system.img             // 실행전 반드시 bootloader/system.img bakcup  
$ sudo ./flash.sh -r -k APP jetson-tx2 mmcblk0p1                              // 적용된 이미지로 Flash


  • mount system.img.raw 방법 
system.img 는 mount가 되지 않으며, system.img.raw만 mount가 되었으며, mount 한 후에 NVIDIA에서 제공하는 SDK가 제대로 설치되었는지 확인하자.

$ mkdir test   //mount 할 장소 
$ sudo mount -t ext4 -o loop ./bootloader/system.img.raw ./test    // RAW File Mount

$ ls test/      // Target File System , APP 
README.txt  bin  boot  dev  etc  home  lib  lost+found  media  mnt  opt  proc  root  run  sbin  snap  srv  sys  tmp  usr  var // Target Filesystem 

$ ls ./test/usr/local/      //CUDA 설치확인 
bin  etc  games  include  lib  man  sbin  share  src    // 미설치 

$ ls ./test/usr/src/      //tensorrt 설치 확인  /usr/src/tensorrt/bin/   , /usr/src/tensorrt/samples/
linux-headers-4.4.38-tegra

$ sudo umount test   // 반드시 unmount

  • flash.sh 사용법
$ ./flash.sh -h

Usage: sudo ./flash.sh [options]  
  Where,
 target board: Valid target board name.
 rootdev: Proper root device.
    options:
        -b  --------- nvflash boot control table config file.
        -c  --------- nvflash partition table config file.
        -d  --------- device tree file.
        -e  ------- Target device's eMMC size.
        -f  -------- Path to flash application: nvflash or tegra-rcm.
        -h ------------------- print this message.
        -i ------------------- pass user kernel commandline as-is to kernel.
        -k  ---- partition name or number specified in flash.cfg.
        -m  ----- MTS preboot such as mts_preboot_si.
        -n  -------- Static nfs network assignments
                               :::
        -o  --------- ODM data.
        -p  --------- Total eMMC HW boot partition size.
        -r ------------------- skip building and reuse existing system.img.
        -s ----- PKC key used for signing and building bl_update_payload.
        -t  ------- tegraboot binary such as nvtboot.bin
        -u  -------- PKC server in @ format.
        -w  --------- warm boot binary such as nvtbootwb0.bin
        -x  --------- Tegra CHIPID. default = 0x18(jetson-tx2)
                               0x21(jetson-tx1), 0x40(jetson-tk1).
        -y  -------- PKC for secureboot, NS for non-secureboot.
        -z  -------------- Serial Number of target board.
        -B  --------- BoardId.
        -C  --------- Kernel commandline arguments.
                               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.
