From 9401780c2c87dc78116eabe30b4eae987b05a921 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20=C5=A0tetiar?= Date: Fri, 19 Jul 2019 15:52:46 +0200 Subject: [PATCH] firmware-utils: mkfwimage: provide human readable error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit While looking at the ath25 build breakage of 19.07 images today I've encountered following error: mkfwimage -B XS5 -v [...] ath25-ubnt5-squashfs-sysupgrade.bin.new ERROR: Failed creating firmware layout description - error code: -2 Which is barely human readable and needs poking into the source code, so this patch makes the error more verbose and usable by mere mortals.
