Factory image seems to stop in fast boot mode

I received my HiKey960 (3 GBytes RAM) in late December and it boots properly into Android with Switch 1 closed, Switch 2 open, and Switch 3 open. I have installed the mezzanine board that provides the USB debug port (/dev/ttyUSB0 on my Debian system).

I have now successfully built the Android images and wanted to flash them onto the device. I removed power from the 960, closed Switch 3 (Switch 1 is also closed) and powered up the board. I then ran the flashing script which stalled at “< waiting for device >”. Since I cannot flash the device, I know it’s still running the factory images.

I rebooted the 960 while running a terminal program on /dev/ttyUSB0 and recorded the information at the bottom of this topic. From all I can tell, “USB bootloader is 4” is a shutdown mode.

Do I need to connect the USB OTG port to use fast boot mode?
If not, what am I doing wrong?

Yes, you need to connect your host to the USB OTG type C port.
Then once connected you should see Hikey is detected/enumerated by your host (dmesg).

Thank you very much for the quick reply. The Android page for building and flashing doesn’t make it clear that the OTG port (USB Type C connector) must be used (https://source.android.com/setup/devices).

Should the UART Mezzanine board be disconnected when flashing?
I have read that if the UART board is connected, a host should be connected so the boot process doesn’t slow down/freeze.

You might consider reading through the device documentation:

Its also unclear how you even imagined that it would be possible to hook something up to a type A receptacle on the hikey960 and expect it to work as a device. A type A receptacle is specifically for a HOST. https://en.wikipedia.org/wiki/USB#Standard_connectors

@doitright: I don’t think the OP mentioned using type A connectors but even if they did there are a couple of devices around that implement device mode using type A connectors. This is typically for magic firmware upgrade modes that do not strictly conform to USB standards when the mode is engaged (bubblegum-96 is the an example of this within the 96Boards family… hopefully now USB type C is common it will also be the last :wink: ).

@doitright: I am the first to admit I am not familiar with current mechanisms for flashing Linux devices. In past decades, UARTs were often the only way to load code onto a base system. Flashing was then performed using the loaded code. The last Linux board I loaded used a dedicated Ethernet connection and TFTP. That is the perspective I come from.

As for “reading through the device documentation”, any links you consider best for this would be greatly appreciated. For me, the documentation is scattered and sometimes conflicting. I have reviewed the following:

Hardware User Manual:

Note that Step 2 of Starting the board for the fist time mentions connecting the Express-Uart board.

AOSP (mentioned previously):
Note that all 3 links under HiKey960 Additional resources are broken.

96Boards documentation Wiki:

Note that almost every link on this page is broken

Linaro documentation:

Note that following the links on this page don’t lead to much.

And, of course, this forum.

Don’t hesitate to report documentation issue or broken link via github https://github.com/Linaro/documentation/issues. Problems with links is that they are not link but pointers…

This is actually optional, but really useful for debugging.

So… one of the problems with maintaining the 96Boards documentation on github is that is often seems to have a better rank in search engines that the actual documentation.

Official documentation is here: https://www.96boards.org/documentation

I have also fixed up the broken links on the wiki.

That doesn’t apply here. There is no flow control nor any other presense detect. The hikey960 will spew out info exactly the same info whether or not the adapter is connected and listening.

Thank you all for the quick and helpful replies.

I suppose the topic of this thread should be changed to reflect something like “newbie trying to determine flashing requirements” :slight_smile:
