Problem: no /dev/serial/by-id

invalid@example.com (Carlon180) — Thu, 06 Jun 2024 15:15:09 +0000

This problem affects my UdooQuad, using on a 3d printer with a RADDS (a shield to build a 3d printer): typing "ls /dev/serial/by-id", OdooUbuntu 18.04 write me a "no such file or directory" error... It is like this directory - but also "/dev/serial/by-path - is not generated and populated.
This information is crucial for Klipper (I need to know how is nominated Arduino Due USB port, that is the MCU of my printer).
I know it is a problem typical of Debian, but all the solutions I found don`t...

Hi All,

I'm asking for your help to make an autorun of an application when UDOObuntu starts.

Actually earlier it was easy to do on Linaro Ubuntu OS just adding a line in the end of /etc/rc.local script. But now it looks like UDOObuntu v.1 does not launching rc.local at all. Any thoughts?

Read only Root FS UDOObuntu 2.1.4 Minimal

invalid@example.com (Gatsu) — Tue, 10 Oct 2017 11:54:13 +0000

Hello,

I have to do a read only File System for my UDOO QUAD. For the moment I decided to use UDOObuntu 2.1.4 Minimal and try to make it rugged by doing a read only root FS.
Is someone already did this?
Do you know which RW mounts should be mount as tmpfs ?
Do you think I should use another Linux like Yocto or Buildroot instead Ubuntu minimal?

For information, I will need to use Qt5 for GUI and Python.

Hello everyone,

I'm using UDOO linux kernel for UDOO IMX6Q board. I'm trying to adopt Xenomai with it. Xenomai requires to disable some configuration variables such as CONFIG_CPU_FREQ, CONFIG_CPU_IDLE, etc.. There's no error in disabling any of them except for CONFIG_CPU_FREQ. It always produces several errors on trying to disable it as many used functions in the drivers files are defined within cpufreq folder. Is there anything that can be done to work around disabling it? for example, can...

udoobuntu minimal fdisk segfault

On the udoo quad with ubuntu minimal when I try to run fdisk it either gives me a segfault or it does something equally strange saying it "cannot open /proc/paRtit)ons" with that exact spelling. I have rebooted and seen this message before. It seems to randomly pick one or the other.

I actually thought maybe I got hacked or something as it is a dedicated server and suggests about breasts ?! This is one of the strangest things I've seen in technology in a while.
