2) File: u-boot-stm32mp157a-fsmp1a-trusted.stm32

3) File: sdtools.sh

2. Insert the TF card into the card reader

3. Insert the card reader into the computer USB port and connect to Ubuntu

2. Enter ubuntu and execute the following command

ls /dev/sd* -----> Check whether the U disk is recognized by ubuntu (if there is a result, the recognition is successful and the disk partition operation can be ignored)

sudo fdisk /dev/sdb

        m can prompt help information,

        ddelete partition
