Dockstar - New USB Stick - Yellow LED blinking after restart

Hello together,

I use a Dockstar with Debian in my Intranet, which is working perfect. Now i wanted to change from a 4 GB USB Stick to a 32 GB Stick. I made a backup of my existing stick with Clonezilla and restored it to the new stick.
Afterwards I checked the file system with gparted under Ubuntu, no failure recognized.

Then I started my Dockstar with the new stick, and first time it boots without a problem. When I started a reboot of the system I can see shortly that all LEDs are off. After some seconds the USB blinks twice and then the Dockstar blinks yellow. After switching off the power supply and switching on it is starting into the system.
Same game while I started again a reboot.

It seems, that the dockstar didn't recognize the stick after a soft reboot.

Is there any chance to get this working?


Thanks in advance,
