2.3 Burn Images 

After download fastboot1.img and fastboot2.img on the board, then can use fastboot 
command to burn images: 

sudo fastboot flash fip  fip.bin 

sudo fastboot flash fastboot l-loader.bin 

2.4 Troubleshooting 

a. After enter the force download mode, if Ubuntu PC cannot recognize the device ttyUSBx; 
this issue can be fixed by input below commands: sudo echo 12D1 3609 > 
/sys/bus/usb-serial/drivers/option1/new_id sudo makenod /dev/ttyUSB0 c 188 0 

b. Need supervisor permission for hisi-idt.py: "sudo python hisi-idt.py" 

c. Need supervisor permission for fastboot: "sudo fastboot" 

d. If download binaries failed with below message: 

Sending fastboot1.img ... 

failed 

failed 

Usually this means you are using the wrong ttyUSBx device; the reason is when connect 
board with the uart cable and usb cable, then PC will create two device nodes /dev/ttyUSB0 
and /dev/ttyUSB1; 

But the nodes which are randomly binding to uart and usb, so sometimes /dev/ttyUSB0 is 
created for the uart and /dev/ttyUSB1 is for the usb port, in this case should use /dev/ttyUSB1 
for the idt; if PC exchanges the nodes then should use /dev/ttyUSB0.
