From ea8b6877a84c6e219bc3c7fe3ef08f7124cf4305 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 28 Oct 2015 07:53:58 +0100 Subject: [PATCH] tools/kwbimage.c: Fix generation of binary header The binary header ends with one lword, defining if another header follows this one. This additions 4 bytes need to be taken into account in the generation of the header size. And the complete 4 bytes at the end of this binary header need to get cleared.
