From 79e984c470f7a2bfa4d292214a985ec39185d935 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Tue, 17 Sep 2019 17:09:33 -0400 Subject: [PATCH] tools: dumpimage: Provide more feedback on internal errors The dumpimage utility errors out in a number of places without providing sufficient feedback to allow the user to easily determine what has gone wrong. Add additional error messages to make the cause of the failure more obvious. Signed-off-by: Andrew F.
