Nvgetty udev issues between ZED SDK and UART GPS how to resolve?

FGR_Mike · July 22, 2022, 2:27pm

Good Day,

I seem to have an issue.
Jetson Nano, JP 4.6.1
Python 3.7

The issue is:
nvgetty enabled = no dialout UART mode = no gps data. However, ZED SDK for sensor data works.
nvgetty disabled = dialout UART mode = gps data. However, ZED SDK fails for sensor data saying it can’t claim the interface.

I need both devices to communicate and work.
I am using ublox f9p gps

How to resolve?

It might be the user not having permission. If nvgetty runs it is group “tty”, but if nvgetty is not running, then it is group “dialout” (both are user “root”). If this is the issue, then a simple fix would be to add your user to group “dialout”:
sudo usermod -aG dialout <your user name>

FGR_Mike · July 22, 2022, 10:15pm

The user has permission to dialout and is added to the group. The only way to fix so far is to chmod 666 multiple times and fight against nvgetty, since disabling it breaks the ZED camera sensor access to the usb ports.

linuxdev · July 22, 2022, 10:19pm

The device special file is not a real file, in the sense it is not on the hard drive or eMMC or SD card. This is actually a driver in RAM pretending it is a file, and so chmod may not work as you expect. During boot there is a possibility that this briefly changes group, but if serial console was on this before, then you’d have to disable it not only in Linux, but also in the bootloader chain (a separate configuration) if serial console is going to be active during boot. Prior to the “chmod 666”, what is the ownership and permissions? If I use the user name “ubuntu” just as an example (substitute this with what your user name really is), then what do you see from:
grep ubuntu /etc/group
(this should show every group membership)

FGR_Mike · July 22, 2022, 10:23pm

Before the cmod 666 only root has access and sudo works.
Here is the group information

$ grep smartmow /etc/group
adm:x:4:syslog,smartmow
tty:x:5:smartmow
dialout:x:20:smartmow
cdrom:x:24:smartmow
sudo:x:27:smartmow

This is highly unusual. I’ve never seen it as “group” root, I’ve only seen it owned by root. There would have to be something custom or strange going on, e.g., perhaps a udev or device tree entry modified something to make it “not group other than root”. Your user though seems to be full admin, so you are right that if the group of the device special file were one of those other than root, then it should work. I’d concentrate on why the device is showing up as group root if this is what is happening.

FGR_Mike · July 22, 2022, 10:41pm

i think only the user root owns it before the chmod
Other /dev/tty like S1, S2, and S3 are crw-rw---- 1 root dialout

But THS1 has no dialout only tty because I suspect is nvgetty.
after chmod we have crw-rw-rw- 1 root tty 238, 1 Jul 22 18:36 /dev/ttyTHS1

Just need this to stick.

linuxdev · July 22, 2022, 10:45pm

One would rarely ever use the UART as owner root. The “rw” permissions of group “dialout” means that if the problem is one of permissions, then your user should not have a problem. The problem with “ttyTHS1” is that it is being used by another process and is not available. The group “tty” means this is set up as serial console and you never disabled serial console. To turn off serial console (at least from Linux, but not from bootloader stages):

sudo systemctl stop nvgetty.service
sudo systemctl disable nvgetty.service

(after this it will revert to group “dialout”)

FGR_Mike · July 22, 2022, 10:48pm

When i perform those commands, it does fix the THS1 error but then for some reason the USB3 is affected and the ZED SDK breaks and throws the following error.

can’t claim interface 0: -6

Which seems to be a libusb error that I do not know how to solve for after a lot of research.

linuxdev · July 23, 2022, 5:33pm

USB should be unrelated to the serial UART, at least in software. The ZED cameras do draw significant power, and this sometimes gets in the way. Also, the ZED wants all bandwidth to itself, so if something else is sharing bandwidth with the camera in “lsusb -t”, then you’ll want to move things around. Overall though, the next step is to use an externally powered HUB on the camera. I suspect this is what is needed because once your UART worked, then the camera should work, and this implies increased power draw.

Also, you’d want to show the logs related to the USB and UART and camera. Best to show the complete new dmesg output, and mention what the last line is prior to starting the action causing the camera error.

FGR_Mike · July 23, 2022, 5:48pm

Well … the USB is a UART and I think they are connected? Anyways, The can’t access interface 0 error seems more of a permissions/resource availability error. There is plenty of power on the camera available there is no issue there. If it was a power issue, the issue would be present regardless of the state of nvgetty.

Yes, and that is a possibility, but the USB with the integrated UART is a very well test interface. In terms of software you could be right that this is a problem, and an update from dmesg might be useful for that. I’m confident that the driver, by itself, is reliable and that the UART won’t have a conflict with USB (exception being a bad device tree on a custom carrier board).

However, if power is an issue, then consider that power delivery through USB could cause issues for any component on that bus (this is quite common). Power can cause a lot of issues that sound nothing like the original issue. It is easy enough to eliminate that as a possibility just by trying an externally powered HUB (if you have one it is about 30 seconds of effort).

Do attach a new dmesg and note where the last line is in the log prior to testing.

NOTE: nvgetty won’t change this, but fixing control to the camera will change power consumption. And if nvgetty worked, then you’ve just verified the driver to the UART works.

I’m not following the logic so let me clarify…

We use the Zed2i. The Zed2i has 2 cameras and several Sensors.
The Camera works great with no issue
I think the driver to access the Sensors gets broken when the permissions are changed, when researching, I came across this error on several other systems all due to libusb permission access.

The hub is not needed, we’ve been testing the Zed on our battery-powered robot for months and It’s great.

I think the real question is what is the Jetson state with nvgetty disabled and why disabling it breaks access to the Zed Sensors.

linuxdev · July 23, 2022, 6:25pm

I’ve seen many issues with Zed when conditions cause them to draw more power (this isn’t necessarily the Zed’s fault). Is the UART being used to control the Zed in any way? If the change in permission by disabling nvgetty causes the issue, but no command or change has occurred relative to the Zed operation, then you are probably right. However, is the UART not being used for control of the camera?

FGR_Mike · July 23, 2022, 6:30pm

I have a ublox ZED-F9P attached to the UART. The ZED camera is attached to the USB3.
When nvgetty changes the permissions the UART access is denied for the gps data.
When nvgetty is disabled, for some reason, the driver for the ZED sensors fail due to libusb

linuxdev · July 23, 2022, 8:10pm

Is the query for GPS data on the ZED-F9P being run as the same user? If not, then that user may need to have group dialout? If that user was already able to access group dialout, then the new application (the one which was just added to dialout) might be in conflict. Are there two applications involved in accessing GPS/UART communications? Are there two different users involved? Or perhaps two threads?

FGR_Mike · July 25, 2022, 1:35pm

Yes, they are the same user.

linuxdev · July 25, 2022, 6:09pm

Is a single program accessing the UART? Or is more than one trying to access it? If just one program, is the access from separate threads? I’m trying to figure out if the denial is from two users (even if from the same program) at the same time. Also, what exact error message do you see, and where do you see it from? This is really close to working, and changing it to group dialout should only help. Stopping nvgetty stops one conflicting program, and it is odd that you would get a permissions error at this point.

FGR_Mike · July 25, 2022, 6:16pm

It’s one program, the GPS program runs on a separate thread:

When GPS program can’t access data it throws a permission denied error.
When ZED Sensor program can’t access data it throws “can’t claim interface 0: -6”

linuxdev · July 25, 2022, 6:23pm

Is it the same program running the ZED which talks to the UART? Where is the exact place the permission denied occurs, e.g., do you see it on command line, or is it from a call inside the program? An exact quote of the error might narrow it down.
