Fastboot mode not booting up the hikey 960 board


#1

When i keep the switches as 1. ON , 2. OFF, 3 ON, i,e so that my hikey960 is in the fastboot mode, nothing boots up and nothing turns on .
Only when I have 1. On 2. OFF 3. OFF , that is when my board turns on. What could be causing this issue.

Is there a problem with my board?

If you plug your computer to the board, what happens on host side when you power on the board, any message in dmesg ?

If you want to reflash your board, you can try recovery: https://github.com/96boards-hikey/tools-images-hikey960/blob/master/README.md

If fastboot is functioning correctly, there should be output from the UART serial console. However, video output or lcd won’t light up, which gives a illusion that the board isn’t booting. Also, a usb device will be detected if you connect the type-c OTG port to your computer, on which you can use fastboot uitility.

Also, as Loic just said. If there really is a problem, you can follow the recover procedure in the official doc.

Hello,
So you mean that when I keep my board switches in fast boot mode, it wont turn on the board ? Lets say I have an hdmi -VGI cable connected to the board and I set it up in fastboot mode.Will it not turn on ?

But when I connect the usb C cable to my laptop and do a sudo fastboot devices, It is showing up my device.

Is there a possibility to see the display on the monitor when I’m in fastboot mode

The purpose of fastboot is to provide a means of recovery and so video output is not necessary. You can use fastboot program on your PC with usb-c otg cable to flash the board. Actually a special fastboot program is booted instead of android. After you have finished your job with fastboot, you can turn switch back to normal to boot into the system.
