From c56935bdc0a8edf50237d3b0205133a5b0adc604 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 28 Nov 2011 09:44:15 +0100 Subject: [PATCH] firmware: Sigma: Skip header during CRC generation The firmware header is not part of the CRC, so skip it. Otherwise the firmware will be rejected due to non-matching CRCs.
