X80 Pros have sdcard compatibility problem now.
I have heard that same thing is happening with another cherrytrails like x98 plus.
But It can be fixed easily with just setting one option enabled.
[Bios – Advanced – System Component – MS Custom Sdbus Driver – Enable]
Real problem is that this option is always reset when dualboot to android.
I have found that It happens when changing [Bios – Boot – OS IMAGE ID].
I think this problem can be easily fixed with just one fix to the “OS IMAGE”
I have sent message to Teclast facebook to make new bios with “MS Custom Sdbus Driver” enabled.
I’m afraid new bios will come So anyone who suffer from sdcard.
So anyone interested with this problem, Please contact Teclast to report this!
