Dear Wig,
Thank you so much for your answer !
About the
kodi image,
good news and bad news here !!
First, good news because
you solved my problem !
Reading your answer I had the feeling you were sure about the image,
so I double-checked everything. Same problem with another screen, another HDMI-HDMI cable... But when I tried to write the image on another microSD card... it worked ! And I'm happy to see that kodi is working (very) well on my Wandboard Quad !
Just the microSD card was failing...But, also bad news !
Because
every 10 minutes... the screen goes black !
The system is still alive because the sound is still here, Numlock's LED blinks when hitting it, I also can telnet to the system...
I made a lot of tests and finally understood how I can reproduce the problem... Very strange behaviour !
When the screen goes off,
I can make it go on again with the following sequence :
Step 1 - unplug USB keyboard
Step 2 - plug USB keyboard again
Step 3 - hit a key
And this only works if Step 3 occurs no more than 5 seconds after Step 2 !
After this sequence, the screen goes on immediately... but it will get black again exactly 10 minutes later...
I tried to do the sequence again before the 10 minutes delay. This is useful because it seems to reset the 10 minutes counter before the screen goes black : the screen will go black exactly 10 minutes after the last Step 1 - Step 2 - Step 3 sequence (it must be complete ! this was not valid when I tried with only Step 1 and Step 2).
Of course I switched off both screen saving and energy saving in Kodi...
Really, really strange...
I can reproduce this exact behaviour with another screen, another HDMI-HDMI cable, another keyboard...
No matter whether Kodi is playing a video stream or doing nothing.
So I think you all should have the same problem... Can you confirm ?Maybe I should ask for help somewhere else...
Another topic in the Wandboard forum ?
Or maybe in geexbox's own forum ?
Thank you again for your answer,
and thanks to the Wandboard team !
