Crash on kernel booting

[yann77500]

Hello, I'am trying to use this interesting project to boot linux on my stm32f769-disco board. However, i can't boot the kernel, it seems memory error occured. I haven't modify the configuration files.

Below you can see start-up log console message :

Have you encountered this problem? Do you have any solution ? Thank you.

Problem corrected with binutils version 2.28.x It was a bug from binutils version. http://lists.busybox.net/pipermail/buildroot/2018-May/222387.html

[LubomirBogdanov]

Hello, could you tell us what did you do to change the binutils?

[LubomirBogdanov]

OK, so I managed to get it working with binutils 2.28.1. Here is what I did:

git clone https://github.com/fdu/STM32F769I-disco_Buildroot.git make bootstrap cd buildroot/ make menuconfig -> Main menu -> Toolchain -> Binutils Version -> select binutils 2.28.1 -> Save -> OK -> Exit cd .. make build
