            Description

            The issue is discovered with NT50 firmware. The pool size is defined to be 128 bytes long however the confirmation packet ODV2_GET_OBJECT_LIST_CNF_T returned by ODV3 is more that 1024 bytes

            More detailed description is done at https://ticket.hilscher.com/browse/PRODGATEWAY-364 

             

            After a review of the ODV3 public header we saw that there are also another packets that exceed the pool element size.
