From 445dc23eb51bc2d7f4466392d36d40fcecf54f65 Mon Sep 17 00:00:00 2001 From: Andreas Bolsch Date: Sat, 28 Oct 2017 19:39:35 +0200 Subject: [PATCH] Handle improperly build image files gracefully Images build improperly (by simply concatenating separate images) were accepted, but anything after the first end-of-file record *silently* ignored. Now emit warning for intel and motorola images upon non-whitespace after first end-of-file record but continue reading anyway. ST ships some images broken that way in their CubeMX packages ...
