Just to have this documented publicly: I was in contact with the Wallys 
support and used this opportunity to point out this problem. I've provided 
references to interesting QCA documents and they were able to fix the problem 
on their end (via QDART).

The current status is:

* there will be most likely no tool by them to allow the customer to fix this 
  problem ("missing boards_id which is shown as 0xff") directly
* they will replace these cards. But they have to be send back to the 
  reseller. My understanding is, that the reseller must then also send back
  his stock to get properly configured cards which can then be given to the 
  customers as replacements. But I am not involved in this process and can
  therefore only guess the interactions between reseller and Wallys.

So it is basically the same process as with 8devices. And Mariusz is for 
example already in contact with an EU based reseller.

Kind regards,
