Can not compile Linux Kernel

invalid@example.com (Iacopo) — Wed, 09 Jun 2021 22:09:36 +0000

Hello everyone,

I was about to recompile the kernel for Neo's board following the guide https://www.udoo.org/docs-neo/Advanced_Topics/Compile_Linux_Kernel.html and got stuck since the installation of the dependencies. I run Ubuntu desktop 18.04.5 and this is the error:

$sudo apt-get install gawk wget git diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm picocom ncurses-dev lzop gcc-arm-linux-gnueabihf

Udoo bolt AMD ACP operation details: where to find them?

Hi everyone,

I'm trying to assist alsa dev guys to make a kernel module for the onboard acp which currently cannot be used.
I asked amd guys, but they answered:

Currently we had added support for only I2S configuration.

Configuring peripheral timer

invalid@example.com (Puneet) — Mon, 14 Jan 2019 10:23:42 +0000

I want to write a kernel module to configure the peripheral timer (using the General Purpose Timer module) on my Udoo Quad board. Currently it is running the below kernel:

root@udoo:~# uname -a
Linux udoo 3.14.56-udooqdl-02044-gddaad11 #3 SMP PREEMPT Tue Dec 6 16:26:55 UTC 2016 armv7l armv7l armv7l GNU/Linux

However, I see that after the board boots up, the timer is already running. I don't know how it gets configured, but the counter value of the timer is seen to be continuously...

Backport for 802.15.4 doesn't compile

The backport for the IEEE 802.15.4 stack doesn't compile for the UDOO NEO (probably the same with UDOO QUAD...). Here are the logs I get :

cgroup submodules in Ubuntu Neo

invalid@example.com (Vinay Jindal) — Wed, 15 Feb 2017 13:00:13 +0000

Hi All,
I posted a query about cgroups support in Ubuntu for UdooNeo Full in another forum. The query is present at:
http://www.udoo.org/forum/threads/linux-cgroups-for-process-isolation.6522/

Basically, I am only able to view 'freezer' and 'devices' submodules in /proc/cgroups file. None of other cgroups submodules like cpu, cpuset, memory etc. are present and hence cannot be mounted. I want to control the usage of CPU, memory, block I/O and network bandwidth for my...

Udoo neo for Loadable kernel module

invalid@example.com (Satya) — Mon, 13 Feb 2017 07:08:09 +0000

Hello

I am interested in learning linux kernel and planning to take up Eudyptula Challenge. Since I would be needing a linux machine, I am curious to know if I can use Udoo Neo for this challenge. If so what changes do I need to make in UdooUbuntu and if not could you please let me know any other board for this challenge?

Support rotation drm

invalid@example.com (Teleco88) — Tue, 24 Jan 2017 10:09:59 +0000

Hi, all!
I'm looking for some drm driver that allows for screen rotation (90,180,270). The driver that brings Udoo by default does not allow me to be able to show images.
Is there any other option I can use? For rotation with the frambuffer I can only mirror the image.
Thanks!
Regards!

The screen shuts off after 10-15 minutes

invalid@example.com (Teleco88) — Wed, 21 Dec 2016 12:41:21 +0000

Hi, friends!
I am making a custom filesystem to use on my Udoo with only the files I need. My idea is to use the Udoo and display images using the screen (LVDS 7 ") and using a C application that shows images in the framebuffer.
My problem is the next one after being 10-15 minutes showing an image, the screen goes out and stops showing.

Anyone know what this may be?
Is it in the activated kernel something related to the energy saving that causes the screen to be turned off after 10-15...

rotation Framebuffer in Udoo

invalid@example.com (Teleco88) — Tue, 22 Nov 2016 11:50:39 +0000

Hi, all!!
I'm trying to make a minimal filesystem to use on Udoo.
My idea is to be able to show things (Image,text) on the display (HDMI/LVDS) without using X11 only the FrameBuffer.
I can draw in the FB but I would like to be able to apply rotation of 90º, 180º, 270º.
I try to change the rotation value of FB /sys/class/graphics/fb0/rotate but I can only put 0 or 1
0 - Normal rotation
1 - Mirror rotation
I have enable CONFIG_FRAMEBUFFER_CONSOLE_ROTATION in the kernel.
Is there any way I can...

Hi all,
I started work on kernel 3.17 for the udoo. I released the source code on github in my git repo (https://github.com/patrykk/linux-udoo).

This has been tested with gpu viv version 3.10.31 so you will need this version of binaries for vivante.

missing ppp kernel module for 3g modems

I'm trying to get wvdial to work so I can use my 3G modem, but it seems like ppp kernel module is missing. Can you add that for the upcoming release? I'm sure there must be more people than me wanting that?

I'm seeking some help with unofficial kernel I'm trying to use (3.14.54 from solidrun and 4.4 from xbian) with openelec. Few months back I had everything running but now I have video on hdmi and 7" LVDS 800x480 but 15" LVDS 1366x768 doesn't work. Kodi is saying the text below. Splash is visible in all 3 cases.

Hello,

I would like to use the more recent kernel version 3.14 but I cannot enable the Wi-Fi and the touchscreen.
Which options should I enable in the UDOO config file to install the Wi-Fi module drivers and how should I enable the touch events on my screen ?

udoobuntu2 - kernel option wishlist

invalid@example.com (Xykon) — Thu, 26 Nov 2015 12:04:49 +0000

Hello all,

While I can of course compile my own kernel with the options I need, I thought it would be good to have a wish-list of things people would like to see added to the official kernel releases. If compiled as modules, those could actually go into a separate .deb package that is optional to install (for those who want to keep their image as small as possible)

At the top of my head I would suggest:

config in /proc/config.gz
tun/tap support (for OpenVPN etc.)

Compile kernel with SPI serial port support

invalid@example.com (Whatdoudoo) — Mon, 26 Oct 2015 08:43:53 +0000

I have an UDOO Quad Rev.D and I would like to activate the serial port SPI2 in the kernel so I can use them from the i.mx6. I chose SPI2 because it is available on the header. I am not sure what I need to add to the kernel files to get it working. I have managed to compile the kernel and get the UARTS working, but I am clueless with the SPI interfaces. Has anyone been able to get a serial port working for the i.mx6? I guess if all else fails, I could bit bang it. Would be nice to get...
