UDOObuntu 2 with Kernel 3.14

I see 1wire made it into the kernel, but the dtsi for the quad hasn't been modified - have you guys verified it works with a 1wire device?

 

I will check it against a ds18b20 next week. Btw in the first release all external pins will be set as GPIOs in the device tree. Then we will investigate how to easily reconfigure the pins (eg dt overlay).

 

tried this weekend - didn't detect any of my temp sensors

 

Hi,
Is it possible to upload the File System for UDOObuntu 2.0 so I can compile QT 5.5. I eventually would like to use QT5 and PyQt to compile and run Gui programs.

Thanks

 

Can't you extract it from image itself?

 

Hi Karohe, did you compile with success Qt5.5 on Udoobuntu2 ? If yes, can you post the procedure to do it, is it more simple for you ?
Otherwise, if you want to have the FS of udoobuntu2, you can try this :

• Insert the SD card with udoobuntu2 into a host PC.
• go to the path in which you want to store the backup file image on your hard drive
# cd <path>
• create the backup of the first 1MB of the device and skip the first KB.
# dd if=/dev/sdx of=<image file name> bs=512 count=2000
(WARNING: THIS COMMAND MAY DELETE YOUR HARD DRIVE PARTITION. PLEASE
MAKE SURE YOU ARE WRITING TO THE CORRECT DEVICE!!!)
• make sure that the partition is mounted
# df -h
• in the output of this command you can see the /dev/sdx item and the relative mounting
point (reffered to as /media/sdcard)
go to the mounting point
# cd /media/sdcard
create an archive of the entire content of the SD partition, specifying the destination path:
# tar -czpf <dest. Path>/<archive name>.tar.gz ./ --numeric-owner
At the end of this procedure you will have two files: one relative to the u-boot and boot
environment with size 1MB, and an archive file with the content of the SD partition.

 

So what worked for me was to basically go through UDOOBUNTU repository and install every package related to qt5. Mind you this is qt5.2.1.
Then I installed and compiled SIP. It took a few try because of some missing packages. But I eventually figured it out using guides online. Then I compiled and installed PyQt 5.2.1. I had some problems with compiling it. The python-dev package was installed in /usr/include. But the compiler was looking for them at /usr/local/include/. This can be fixed in config file before compiling or just by being laze and copying those files to /usr/local/include. That's what I did and it worked.

Now I can create a GUI in my ubuntu in my desktop and run it on UDOO. pretty sweet.

 

Any time frame for a re-release with bug fixes, new features, etc.?

 

I'm sorry, but not before end of November.

 

the real answer is not until their next kickstarter to make it look like the software works...

 

Beta 3 for UDOO Quad is released!

 

YAY!

 

Except it doesn't boot up!

 

please, could you connect to the CN6 micro-USB port with the J18 jumper inserted, open the serial port and see where it hangs?

 

Looks like this is a server version. I can log in as udooer:udooer. To get a desktop WIMP interface, I'm on my own?

 

Has anyone been able to use this new beta in a desktop environment?

 

Could you please post the result of:
service lightdm status

and test if
service lightdm restart

helps? You could also try to reflash the SD image, for me LigthDM starts automatically.

 

lightdm start/running, process 839

 

Have you changed anything in u-boot environment variables (eg. video)?
By default this images turns on the HDMI port. In any case, if X will not start, you will se a text-based login on the HDMI video out. Is your screen recognizing the input signal or neither that?

 

Just reflashed the uSD card, no changes made to u-boot environment variables. There is an error message early in the boot sequence saying "** Unable to read file uEnv.txt **".
