USB 3.0 support for beagle bone AI.

If it is an option, you could also consider GigE camera since the BB-AI has a high-throughput interface for it (Gigabit Ethernet). Many of these cameras are available in GigE variants too.

However, I'd just like to point out that it can be an uphill struggle getting the open source software running for GigE cameras on ARM. I didn't succeed in my limited tests, I had some runtime errors I never managed to get to the bottom of..

Is your camera supplied with software, and have you been successful installing it or compiling it on ARM and trying to run it, and see what happens with USB 2.0? (i.e. deliberately configure for a much lower frame rate or resolution).

Yep.GigE may be another option. But in that case I need to change camera itself which is not feasible for me.

Basler cameras run on pylon software. I have successfully installed it (Basler have provided separate arm image with c/c++ support). They have provided python wrapper for it as well.

According to the company, USB 3.0 cameras will get detected on USB 2.0 ports but can't be used at all(There are different cameras with lower frame rate support for USB 2.0. One in the ACA category does not support it).

I can compile the codes using their software and it gives me error like "USB 3.0 compatible port required."

I have tested that camera with same software on my linux pc. It works absolutely fine with USB 3.0 and gives same error as of arm for USB 2.0 port.

The answer is simply hidden.

sudo /opt/scripts/boot/bbai_usb_host.sh

This executes:

echo "host" > /sys/kernel/debug/48890000.usb/mode

Which puts the USB-C 3.0 hub on the BeagleBone AI into 'USB Host Mode' and allows devices to be detected. While the HDMI isn't currently supported on my device, the USB ports are, and the devices connected were detected. So long as your USB hub back powers the ports, then set the right mode for the USB hub and it'll work fine. You may want to change the other modes as appropriate.

This solves the problem. But now my usb hub is getting detected as 2.0

On linux machine current usb hub is detected as both 2.0 and 3.0

So is this due to fault in usb-hub?

Or there is any mode other than host and drvice that can help?

HERE HUB IS BEING DETECTED BOTH AS USB3.0 and USB2.0

It may simply mean the USB 3.0 controller can negotiate USB 2.0 as well, depends how the driver works.

Have you tried connecting a USB 3.0 hub to it, and then your camera? What does it negotiate at?

Because the output provide shows you're connecting a GenesysLogic USB 2.0 hub. Which either means your connected hub is only USB 2.0 or the driver for the GenesysLogic chipset can only negotiate USB 2.0

Hi cstanton

The hub which I am using is USB 3.0 and it is showing GenesysLogic USB 2.0 hub on BB and both 2.0 and 3.0 on linux.

I did try it on windows. One thing I noticed is Camera does not show up when I connect hub with external power supply along with c type of PC.

May be it's problem with the hub. When you tried connecting it with your hub, dis it show any problem on USB 3.0 except HDMI port? Have you actually tried connecting any USB3.0 device like hdd or something?

Can you make sure that your hub is connected as USB3.0 host only? If yes then I ll change my hub itself....

Thanks.

I'll check it out with the USB 3.0 hub and devices I have.

Until then, have you ensured that your kernel is up to date, and the operating system? bbb.io/upgrade

debian@beaglebone:/opt/scripts$ git pull returns Already up to date.

uname -r returns this  4.14.108-ti-r127

Is this version okay?

Make sure you also run

sudo tools/update_kernel.sh

Your kernel looks like it may be out of date, or at least there are two more recent versions you can update to:

https://rcn-ee.com/repos/latest/stretch-armhf/LATEST-ti

ABI:1 LTS314 3.14.79-ti-r92

ABI:1 LTS41 4.1.30-ti-r70

ABI:1 LTS44 4.4.155-ti-r155

ABI:1 LTS49 4.9.147-ti-r121

ABI:1 LTS414 4.14.108-ti-r127

ABI:1 LTS419 4.19.94-ti-r36

ABI:1 LTS54 5.4.20-ti-r5

I run this command

sudo tools/update_kernel.sh --lts-5_20.

kernel got upgraded. Then I rebooted it but board is not booting at all..........

D4 led is flashing constantly and nothing else.

Did I crash os/kernel? What can I do now ?
