Bug ID: 11051
Summary: runtime issue on STM32 with usage of binutils 2.29.x
Product: buildroot
Version: 2018.02
Hardware: All
OS: Linux
Status: NEW
Severity: major
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: christophe.priouzeau at st.com

Target Milestone: ---
Since the default usage of binutils 2.29.x, on stm32 we have an issue at
runtime.
Error seen at runtime:

After a bisect, the issue are present since this commit :
37e1e6cf6d133afeed1be98c5d5542cd00664efb package/binutils: switch to use 2.29.x
as the default version
How to reproduce:
git clone git://git.buildroot.net/buildroot
cd buildroot
git checkout -b work 2018.05-rc3
make stm32f469_disco_defconfig
make
./board/stmicroelectronics/stm32f469-disco/flash.sh output/
