From 3140d380422e3b6416b5dbdc951f90b006a4eaac Mon Sep 17 00:00:00 2001 From: Klaus Kudielka Date: Sat, 17 Aug 2019 15:52:01 +0200 Subject: [PATCH] base-files: upgrade: add case to export_bootdevice MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The factory uboot of the Turris Omnia boots with "root=b301", and we instruct new users to sysupgrade from there (e.g. method 1, step 7). Currently, this will fail with "Unable to determine upgrade device". Add a new case to export_bootdevice, which parses the hex argument.
