Android fastboot waiting for devices

Question

I am trying to load a customized kernel on my NVIDIA test git. I typed fastboot boot myImage after which which I get:

 
<         


        

Answer 1

In my case (on windows 10), it would connect fine to adb and I could type any adb commands. But as soon as it got to the bootloader using adb reboot bootloader I wasn't able to perform any fastboot commands.

What I did notice that in the device manager that it refreshed when I connected to device. Next thing to do was to check what changed when connecting. Apparently the fastboot device was inside the Kedacom USB Device. Not really sure what that was, but I updated the device to use a different driver, in my case the Fastboot interface (Google USB ID), and that fixed my waiting for device issue
