From 8a98158f8bd5ede3197c8c62fb4099ff7e48e7a7 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Wed, 14 Feb 2018 11:39:48 +0100 Subject: script: Make the get_default_envs.sh script working with newest u-boot This commit fixes several issues: - Use ${OBJCOPY} if available, fallback to system default's objcopy if not present. - Extend the script to accept different build directory than current one. It is extremely handy with OE usage, where source code is separated from build.
