Thanks ! I was almost sure it was a simple thing, but I've never investigated since most of my boards are on WiFi .
I will commit a patch in Armbian github ...
Yes ! I was blind, because I've only search in my stuff, the glitch was elsewhere :
@megous , Megous 5.0.y branch has USB0-IDDET wrongly on PC6, one of the eMMC data pin, I've fixed it by assigning it to the good PC15 pin.
Everything seems to be working very well. I've tested the USB3, works fine. +300MB/s.
5G wifi works great (5MB/s)
It is fast for a quad-core. Only my Odroid C2 can keep up when it's overclocked to 1.75Ghz + ram OC 1104Mhz. It can't keep up at stock settings.
I've used a mid-large heatsink with a 5V fan connected at 3.3V and while maxed out for 2hours it didn't go over 52°C.
Last time the temperature shot up to +70°C after a second maxed out. It's not doing this anymore.(I don't know why, it's the same heatsink, just another image)
Now it does throttle at 60°C. It goes down to 1.3Ghz. So this is a big difference. Maybe this could be done a bit better. Example : at 70°C to 1.5Ghz and +80°C to 1.3Ghz?
It stays at 65°C and 1.3Ghz with heatsink and without a fan.
So without a fan you don't have a good performance right now.
I couldn't get acces to the eMMC. Maybe this still needs to be added.
