The issue was separated from other threads by advice of DanieLLL.
What has been distinguished so far is
I) A way to enable USB 3.0 port functioning as with USB 2.0 speeds[ by the attached patch application which is a substitution of extlinux.conf file and copying the dtb to /boot ]
II) power-tree modification of dtsi [that method I have not had a chance to test yet, but it seems the same as the above]
II) the second method which is being tested
Please replace Linux_for_Tegra\bootloader\t186ref\BCT\tegra186-mb1-bct-pmic-quill-p3310-1000-c03.cfg in
It was said somewhere at documentations that USB 3.0 has that speed. [theoretical knowledge found from within documentations]
At the default carrier board it was somehow 120 fps as it stated for Zed camera performance[that is from documentations on Zed], as far as I know.
But with Usb 2.0 it results in Zed camera produces 4 fps approximately
As it is said in the Wikipedia:
USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS)
that can transfer data at up to 5 Gbit/s (625 MB/s)
I have no usb 3.0 devices locally. But at a remote place it was Zed tested with the default carrier board. Application named Zedfu. Which won’t start at commtech board complaining about USB 2.0 mode. So the answer is rather Yes. It is able to achieve a decent speed in default carrier board.
the below is the last response from comm tech guys:
There is a potential for that fix to work however we cannot guarantee
that it will fix the USB3 on our carrier boards. We are still working on a fix
for USB3, and have some preliminary results where the USB3 is working on the TX2,
however the fix is not yet stable. I will update you when we have a viable fix
when it is available.
I shall determine which is the the config set according to the adaptation guide and I will update you soon.
It is rather the config 2 by now. Since it is the default. The cfg replacement with JetPack initiated flash OS to Jetson hasn’t resulted in usb port working. Tomorrow will provide more info and demsg after application of the power-tree patch. Tegra_Linux_Driver_Package_TX2_Adaptation_Guide.pdf (897 KB)
Config #2 is the same as it is installed by the default for the default carrier’s board . Jetpack 3.0 was used for flashing the Jetson but with the configuration file substituted.
And now the config is applied.
Just now I have not camera, but soon I will get it and will update the post there. I will execute lsusb -v and will attach its output there. It should display either it is in high-speed or in super-speed mode.
The attached there file is from the case when commtech carrier board is used: kern.log kern.log (249 KB) kern.log.1.log (476 KB)
It seems that we got USB 3.0 Zed Camera application functioning somehow woth the instructions above.
I am just wondering how to know if the USB 3.0 Zed camera works in superspeed or a highspeed mode.
Shall that be determined based on fps rate somehow?
You can see the mode the system is logically using with “lsusb -t”. The right side gives the mode of operation (not necessarily what actually gets through, but it does determine clocks). It’ll be 1.5M, 12M, 480M, or 5000M (where “M” is megabit/sec…USB3 would be 5000M).
If you want to test the actual physical throughput, Passmark sells a USB 3.0 bandwidth tester which is a hardware USB loopback.
Making a USB 2.0 bandwidth tester would be pretty easy using a USB → serial adapter to hack up a serial loopback but I don’t see a cheap USB 3.0 → serial adapter to quickly make a hardware loopback. Alternatively, there are USB devices that can transmit up to 5Gbps that could be tested.
So, if the port can do that, it is in good shape. I only see 2 other USB bandwidth testers other than the Passmark one and they are both more expensive. Or you could just test streaming from the Zed camera as fast as possible.
I talked w/connecttech as well and last I heard, they were still working on USB 3.0. I’m guessing your Zed camera is working as USB 2.0? Does the lsusb -t show superspeed (5000)?
RobertKitt recently asked: “what could have caused” “i need the usb3.0 to fully work at full speed. my current hardware is: Tx2 + orbitty carrier board.”:
well i can't try the usb_fix because the device keeps rebooting.
what i did what replace the

then i ran the command:
