From 1bdc0334ff6273761b2e7fda730cdcc7e1f46862 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?St=C3=A9phane=20Veyret?= Date: Fri, 26 Jun 2020 12:41:16 +0200 Subject: [PATCH] package/rpi-firmware: fix startup file names MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When booting, a Raspberry Pi will load the appropriate start files, depending on the provided configuration. For example, if the config.txt file contains ’gpu_mem=16’ the board will automatically load the cut-down startup files (start_cd.elf and fixup_cd.dat on non-Rpi4). Unfortunately, even when the appropriate version is selected in the configuration menu, if the rpi-firmware makefile takes the good files, it renames them to non-qualified, i.e. start.elf and fixup.dat. But as these are not the files searched by the Raspberry Pi, the board will not start. This patch will set the names of the files to load as constant in the config.txt file. This guarantees that the rpi firmware blobs do not take any other corner-case decision based on any other as-yet unknown conditions. This eases the maintenance, as only the names of the source files matter; the destination filenames are constants, and so are the filenames in config.txt.
