From mboxrd@z Thu Jan 1 00:00:00 1970 From: Romain Naour Date: Sat, 12 Jun 2021 12:24:49 +0200 Subject: [Buildroot] [PATCH] Config.in: disable PIC/PIE for microblaze Message-ID: <20210612102449.8429-1-romain.naour@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net As reported by Toolchain-builder project [1], the system doesn't boot when PIC/PIE is enabled for glibc based toolchain (the init process hang). Also, hardening features may not be wanted or possible for such slow soft-core cpus [2]. Like for NiosII, disable BR2_PIC_PIE.
