Please set the updatecheck variable again. The input editor of U-Boot is very rudimentary, especially the delete key does not work as expected. It deletes characters only visibly, because the terminal emulator on your PC side interprets it correctly, but in reality the delete character is added to the input line. The "Trying update from usb+0000000" shows, that there is something wrong. This should be "Trying update from usb 0 with update.scr".

Thank you for the fast answer.
I think we found the problem 
In the file "u-boot-2012.07-f+s-V2.1/include/configs/fsvybrid.h"
and

Can you foresee when it will be implemented on the NetDCU A5?
Well, I checked my GIT repository. We actually have implemented this in January 2015. But as a matter of fact we did not have a release since then. So yes, the official version is still missing this feature.
I think the best thing is to have a maintenance release for Vybrid as soon as possible. This will bring a lot of small bug fixes and a better/newer U-Boot and Buildroot. However our schedule is rather busy and the holiday time at the moment is slowing down things, too. So I believe I can not promise a release before September.
But you can already check the update feature right now by using an SD card. Later when the release is out, you can switch to USB stick. It will work the same there.

We have released fsvybrid-V2.2. Included in this release is also the new U-Boot with USB host support. Now installation and updates with USB are possible.
