Khadas VIM3 testbuilds

Portisch · 25 September 2019 06:10

We have news about the “green” screen issue when using VIM3 and the latest Khadas firmware from 0907: https://dl.khadas.com/Firmware/VIM3/Android/VIM3_Pie_V190907.7z

As some users already have seen the colors on using CoreELEC weren’t correct (green). We were searching for a solution to fix our kernel to show correct colors. This wrong colors are introduced by the newest Amlogic patches included by Khadas boot loader and Android kernel.

So everybody who have this issue or even not can try this testing CoreELEC update file. It’s based on latest nightly. The image should work even if you have the old (before 0907) OR the new firmware (0907) installed. Maybe it’s also possible for some users what had need to downgrade because of this issue to upgrade the VIM3 firmware again to 0907 to confirm the fixes are working!

If you updated to this test build please open a SSH connection and post the output of:

dmesg | grep 'com register:'

and tell us your actual used VIM3 firmware and the used TV.
And for sure, please tell us if the colors are correct now

Are the 4k movies working with the last nighlty version?
https://relkai.coreelec.org/

Blakey · 29 September 2019 16:38

4K works with CoreELEC-Amlogic-ng.arm-9.2-devel-1569588153.tar but on 50/60fps with small GUI issue during playback, with the Nightlies the screen is green if we have newest Android on eMMC

vpeter · 1 October 2019 08:07

Not that this be important in any way but I would like to hear what temperatures you guys have on VIM3? In idle and on playback.

Wizzi07 · 3 October 2019 20:59

My idle is normally around 40• and highest temps after playback/large library updates etc are 52•.
That’s on Vim3 pro with the khadas case and heatsink and also the bottom plate heatsink “mod”. no fan I’m still waiting for the fan to be delivered.

A quick question while I’m posting… do you have any idea when install to emmc will be reintroduced for the vim3? I know you were working on the green screen bug but looks like you’ve solved that problem now. I ask because both my sd cards seem to have become faulty were they corrupt every time the box is rebooted and I don’t really want to buy a new one if the install to emmc option is going to be brought back soon .
Thanks

Rastus · 3 October 2019 21:17

For an ambient of 26C, idle is 39C and during playback of 1080 video temp never exceeds 44C. I have the normal heatsink on top and a similar one to Startv Khadas VIM3 testbuilds on the bottom.

Portisch · 4 October 2019 06:13

Since the last nightly the new install to internal ceemmc got added.
Just open a SSH connection and type ceemmc -h for help or ceemmc --help for more detailed help.

A “how-to” in the forum will be added next week, depends how much time I have left

DAMM · 4 October 2019 09:14

Works for me, thx.
