Preparing The Patched BSP

tip

You could safely skip this whole step, if the Patched BSP has been provided for you. (Typically contain the board name, such as 'J120' in the zip file)

For Auvidea J120

What You Need:

1. Check the latest firmware version from Auvidea Firmware, and download the zip file.
2. Download the corresponding L4T BSP (inside which provides Linux kernel, bootloader, NVIDIA drivers, and flashing utilities)

The Steps

1. Unzip the BSP and Sample Root Filesystem, using command line to preserve the correct permissions

   sudo tar -xpf <BSP zip file>

   sudo tar -xpf <Sample Root Filesystem zip file>

   # use sudo cp -a to copy the Sample Root Filesystem to rootfs folder inside BSP

   sudo cp -a <Sample Root Filesystem>/* <BSP>/rootfs

2. Rename the extracted Linux_for_Tegra folder, to indicate its target Auvidea board and firmware version. Such as Linux_for_Tegra_J120_Dec2019

3. Extract the corresponding J120 / J90 Firmware

   sudo tar -xpf <Firmware zip file>

4. Navigate into the Auvidea firmware's Linux_for_Tegra folder, copy the files to overide Nvidia's Original, preserving permissions

   sudo cp -a * <BSP Root Folder>

• Double check by ensureing all relevant files in the BSP's folder is the same modification dates as the Auvidea's Firmware folder.

5. Apply binaries

   sudo ./apply_binaries.sh

6. You are done!

Flashing Your First Image (Clean Install)

• to flash every partitions with fresh build of system.img:
  sudo ./flash.sh jetson-tx2 mmcblk0p1

tip

Addtional Nvidia Libraries (e.g. CUDA, cuDNN), could be installed by Nvidia's SDK Manager, by

1. Boot up TX2 into Ubuntu
2. Plug in the debugging USB to host Linux machine; TX2 should be mounted as a network device automatically with 192.168.55.1 address
3. Thereafter, the SDK Manager could do the install automatically
