Klaus, you may want to try updating to version 37 first, and then to 39 or 41.
Hello, thanks. I tried to flush 37 out from an running System: reboot - F7 - prepare - fail. Then I tried the same with an power off cycle the same.
Then I took an other device an connected just Keyboard, VGA an the stick with the BIOS and again:boot F7 Version 37,39,41 and all fine.
Then I tried direct 41 with four other devices, all OK
At the end I removed the first device from HDMI, USB cable hub with mouse,keyboard and touchscreen, connected just VGA and mouse and then also 41 OK
I do not understand why, but it works :
So do you mean we're supposed to upgrade all versions ... I think I broke DE3815TYKE while updating from 0ACCT011 to 0ACCT014 Do you know where all versions (and codenames) are listed ? this is so confusing to me
I tested about 20 units of this device and all work fine. Just connect a monitor, keyboard, mouse and a USB with the newest BIOS. During start press F7 and start the update.
That's what I just did ... the system is still booting but behave differently
Please confirm that newest BIOS for DE3815TYKE is TY0044.BIO :
Now I plan to downgrade to v24 to support headless usage :
I use TY0043.BIO which is fine for us.
The linux booting problem without monitor we also have -> we connect always a monitor
