How to run the setup script?
The Setup Script (setup.sh) is located in the Processor SDK Linux J721e installation directory. By default, this directory has a name that has the form ti-processor-sdk-linux-j7-evm-<version>.
Then run the script:
./setup.sh
mount your SD card on this ubuntu
By default Ubuntu uses “dash” as the default shell for /bin/sh. You must reconfigure to use bash by running the following command:
sudo dpkg-reconfigure dash
Be sure to select “No” when you are asked to use dash as the default system shell.
The mksdboot.sh script can be run from any location but must be run with root permissions. This usually means using the sudo command to start execution of the script. For example:
------------------------------------------------------------------------------------------------------------------
sudo <SDK INSTALL DIR>/bin/mksdboot.sh --device /dev/sdX --sdk <SDK INSTALL DIR>
sudo /home/etastc8/ti--sdk-linux/bin/mksdboot.sh --device /dev/sdb --sdk /home/etastc8/ti--sdk-linux/
sudo /home/etastc8/ti-processor-sdk-linux-j7-evm-08_00_00_08/bin/mksdboot.sh --device /dev/sdb --sdk /home/etastc8/ti--sdk-linux/
#Replace the /dev/sdX with appropriate device name
----------------------------------------------------------------------------------------------------------------------
Please run the following command to install all packages required to by the makefile targets.
host# sudo apt-get install build-essential autoconf automake bison flex libssl-dev bc u-boot-tools python diffstat texinfo gawk chrpath dos2unix wget unzip socat doxygen libc6:i386 libncurses5:i386 libstdc++6:i386 libz1:i386 g++-multilib

Download Compiler toolchain
On the download page, you will find links to the recommended compiler toolchains. Download and extract them into your home directory. Note that you have to download both the toolchains for ARMv8 and ARMv7. Make sure to update your PATH to include the path to toolchain.
GCC92PATH=$HOME/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin:$HOME/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf/bin
export PATH=$GCC92PATH:$PATH
Required Host Packages
Please run the following command to install all packages required to by the makefile targets.
host# sudo apt-get install build-essential autoconf automake bison flex libssl-dev bc u-boot-tools （上面运行过了）
GCC92PATH=$HOME/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin:$HOME/gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf/bin
export PATH=$GCC92PATH:$PATH
make clean
make all
All the install targets copy the files in the rootfs pointed by the DESTDIR variable. By default, Rules.make points the DESTDIR to the NFS path for filesystem. If you want to install the files to the SD card, you should be able to specify different path to DESTDIR on commandline. e.g. run following for installing everything in the SD card rootfs.
确保插入已经分好区的SD Card，同时rootfs与boot文件夹可以访问
host# sudo DESTDIR=/media/$USER/rootfs make install
#Replace the path to SD card rootfs partition as appropriate
Installing boot binaries
All the install targets copy the files in the rootfs pointed by the DESTDIR variable. make install command only copies the files in rootfs. If you have built either of system firmware or u-boot, you should copy these binaries in the boot partition of the SD card. e.g. run following to copy boot binaries in SD card boot partition.
host# sudo cp board-support/u-boot_build/a72/u-boot.img board-support/u-boot_build/a72/tispl.bin board-support/u-boot_build/r5/tiboot3.bin /media/$USER/boot
#Replace the path to SD card boot partition as appropriate
