5.3.1 Program SD Card
By default, the SD card includes the U-boot, Linux Kernel and root file system which can be used
to start-up the COMX-P2020. If the SD card is damaged, we can program it at the Linux host
with a USB reader as below:
 Create the /local/tftpboot/COMX-P2020/current directory at host, and copy the release
file: COMX-P2020.bsp.tar.gz to the directory: /local/tftpboot/COMX-P2020/current
[percy@localhost current]$ sudo chmod 777 /local/tftpboot/COMX-
P2020/current
[percy@localhost current]$ ls -al COMX-P2020.bsp.tar.gz
-rwxr--r-- 1 percy percy 462501957 Dec 9 14:57 COMX-P2020.bsp.tar.gz
 Extract all the BSP targets from the COMX-P2020.bsp.tar.gz:
[percy@localhost
current]$ tar zxvf COMX-P2020.bsp.tar.gz
[percy@localhost current]$ ls -al

 Insert the MicroSD to a USB reader, and connect the USB reader to the host.
 Check the device name for the USB reader. The following command shows that the device
name for USB reader is /dev/sdb.
[percy@localhost current]$ ls -al /dev/sd*
