@balbes150
I check the old version 20190425 on EDGE-V and Caption.I got the same phenomenon.

No system crash occurred.
Bluetooth adapter lost.

balbes150 · July 27, 2019, 12:03pm

Okay, now there’s a starting point in the source code when the system doesn’t crash. Now we need to find the culprit falls.

balbes150 · July 27, 2019, 8:50pm

Test version 20190727.

Frank · July 29, 2019, 12:53am

OK, I will do it today.

Frank · July 29, 2019, 1:29am

@balbes150

The problem of system crash did not recur. Can you tell me what caused the system crash and how you solved it?
Bluetooth adapter lost again.
Mouse returns often fail when entering the settings interface.This won’t happen on other interfaces.

balbes150 · July 29, 2019, 5:53am

I haven’t finished the process yet. When I finish, I’ll write the result.

This is the next bug that needs to be dealt with.

Describe more the bug.

@balbes150
I later tested the bug again.
I went into the settings to check the Bluetooth device. When I wanted to go back to the previous menu, the right mouse button did not respond.It often takes a certain amount of time for the system to respond.I returned the previous menu to the other.One thing I noticed was that when the settings returned unresponsive, I moved the mouse to the settings option. The content on the right side was blank. I think it might be a carton caused by loading information about the settings option.

@Frank
Perhaps the reaction to the mouse button depends on the location of the cursor. I have this happen on a different TV boxes (AML RK) I just move the cursor to another location and the right button starts working.

Frank · July 29, 2019, 6:43am

@balbes150 I will try it later.

Frank · July 29, 2019, 7:25am

.
If the information on the right side is empty, it cannot be returned at any location.

balbes150 · July 29, 2019, 2:49pm

New image LE 20190729.

balbes150 · July 30, 2019, 1:19pm

Maybe I found the “culprit” of the fall of LE.
If you roll back the rkbin package and the u-boot settings to the old version, the images stop falling.

To eliminate the error, @Frank you can check the latest version 20190730 for drops ? I tested it on all my edges with one common dtb by default, everything works on EDGE+captain and EDGE-V.

wanthalf · July 30, 2019, 11:08pm

How can I download the image? On Yandex, I am only getting “Произошла ошибка”.

I am using the image 20190628 and I have no crashes, but terrible (unusable) HDMI sound issues.

UPDATE: OK. I just overlooked the download button at the top.

Frank · July 31, 2019, 12:53am

@balbes150. I will test it today.

Frank · July 31, 2019, 12:54am

@wanthalf . There you can download the image.

Confirmed. It does the initial FS resize, but then it does not even start KODI, just dumps tons of crash dumps on the screen.

Frank · July 31, 2019, 8:08am

@wanthalf
This is probabilistic. Thank you for your test. This bug is being solved.

balbes150 · July 31, 2019, 8:09am

How does the 20190729 version behave ?

Frank · July 31, 2019, 8:47am

@balbes150. I am testing with the 20190729.This version performs well.There was no system crash inEDGE-V or Caption.
