1. Wifi working.
2. External SD working
3. Matched IOMUX configuration to align with the Android image. Managed to work out how compile C programs to run under the Android image.
4. Stripped out unnecessary device initialisation from the original HDMI dongle source.
5. Enabled EGL and GLES HW Acceleration in Ubuntu (big thanks r2zk).
6. Unity desktop I think is partially HW accelerated.
I plan to push kernel patches in the coming days. There is still a fair amount of work to do due to thermal/CPU freq driver patches in the kernel and lack of PMIC on the GK802.
Update: Changes are now merged into the main repo https://github.com/imx6-dongle/linux-imx. If you want to build the kernel then use imx6_gk802_defconfig.
Here's a video to demonstrate what's been achieved and how capable the IMX6Q is. In the video Firefox seems sluggish, however this is easily compensated by the fact I run glmark-es2 whilst simultaneously playing a 720p video.
Compared to the Chinese SOC manufactures it is miles ahead in the availability of reference documentation and Linux support. The video playback is pretty impressive and I hope that we will see XBMC development commence at some point.
Great work! Do you know if OpenCL drivers are available as well?
ReplyDeleteI can confirm that OpenCL is working:

Could you try cgminer? https://github.com/ckolivas/cgminer
DeleteVery cool! Congratulations on getting wifi and accelerated graphics to work. Looking forward to run a fullly functional Ubuntu on the GK802.
ReplyDelete@rahul OpenCL drivers are available for i.mx6. If he got the Vivante blobs to work, I suppose OpenCL should work too.
When running clinfo, i got segmentation fault. do you know the reason?
DeleteVery cool.

ReplyDeleteAwesome!
ReplyDeleteGlad you have success, looking forward to see your patches in repo!
ReplyDeleteNice progress. Did you in any way modified your GK802 heatsink for it to be more stable under the load?
ReplyDeleteThere were some freescale patches for thermal management that helped improve the heat situation, but under load some kind of heatsink is still required. My GK802 is uncased and I just place the external metal casing on top of the CPU as an intermediate solution.

ReplyDeleteThis is great work so far! I'm really looking forward to seeing your release.
ReplyDeleteIf you need any help in testing let me know.
How did you enable EGL and GLES HW? :)
ReplyDeleteI just got my Wandboard with a i.mx 6DL, and I only get software acceleration when running glxgears :((
Take care,
Hi, I will provide instructions so that you can try on Wandboard.
DeleteHi, That would be awesome! thanks :)
DeleteHi Jasbir
ReplyDeleteI have a few question about this ubuntu (gk802) if u have some time I am wondering,
Can i run apache+mysql after install ubuntu on this device?
if it ok , what do u think about apache speed on this?
Can i Configure desktop Permissions (example just run firefox )like ubuntu desktop?,
and is there any heat problem when using ubuntu ?
what do u think ubuntu and android 4.0.4 on this device ?
could you share your experience (pros an cons)?
Thanks
Anyone seeing this on their serial root console?

Fix for this in the repo https://github.com/imx6-dongle/linux-imx.
DeleteDo you know exactly what file or diff ?
DeleteI have another board (wandboard) with the same problem.
Thank you.
Hi, it was cause by double initialisation of the cpu regulator. See https://github.com/imx6-dongle/linux-imx/commit/c6f66631dd2dedcc597d016de124e67a017c4131
DeleteFantastic work! I have just purchased this device only because of your success! Thank you, Im keen waiting for the delivery...
ReplyDeleteI am seeing the
ReplyDelete[ 64.737685] COULD NOT SET SOC VOLTAGE BACK!!!!
and
[ 64.737685] COULD NOT SET PU VOLTAGE!!!!
messages on Ubuntu 12, kernel 3.0.35+ when coming out of suspend or into it.
The kernel runs fine, and can do networking till these messages occur.
I'll look around elsewhere for the messages in the sequence I'm seeing, but this was my first place seeing the SOC voltage message
Could see if this works - https://community.freescale.com/thread/306679
