Other default on the line, after setting enter Exit to

Select a third option serial port Setup

A set/DEV/TTYS0 (My Notebook is with the serial port without USB to the serial port so this only ttyS0 can)

E Set 115200 8N1

F and G Place no

Setup is complete, exit, select Save Setup as DFL

Exit after exiting, restart Minicom, minicom Setup is complete

2. After reboot:

1> get Root (because running minicom requires root, changing file properties doesn't work)

2> Input: minicom

Start the Connected Development Board and the loading content will appear on the screen.

Loading will see the system started from eMMC, eMMC we can simply think of as a built-in SD card.

Enter will appear "[email protected]"

3>CD to a directory in the Development Board root cd/tmp

4> input RZ

5> then press CTRL + A and select the first Zmodem, then select the file okay you want to burn.

After uploading ESC exit, Ctrl+a+q exits Minicome.
