This section describes how to migrate the compiled Qt (QT5.15)
Relevant file access path, Baidu cloud disk：IDO-SSD20X\open_source\rootfs

• Copy rootfs_qt_share.tar and disp_init_cc0702I50R to U disk (SD card);(See the “Initialization screen” section for the generation of disp_init_cc0702I50R.)
• Connect the USB flash drive to the board and mount it;

# echo UDISK > /dev/udisk_4g    //Switch 4G mode to USB mode
# mount -t vfat /dev/sda1 /mnt    //Mount the u disk

• Enter the mount directory of U disk to execute:

# tar -xvf ./rootfs_qt_share.tar -C /
# cp disp_init_cc0702I50R /

The root directory will have three files: qt_share_env.sh analogclock disp_init_cc0702I50R

• Configure the Qt runtime environment and execute:

# source /qt_share_env.sh

• Run the initialization screen program:

# /disp_init_cc0702I50R &

• Run the qt demo:

# /analogclock

• Configuration boot start

#vi /etc/profile
