Hi,
I am trying to run u-boot on a STM32F746G-DISCO device. I am configuring u-boot with stm32f746-disco_spl_defconfig.
But nothing happens on the LCD nor on the serial console. I use screen /dev/ttyACM0 115200 under Linux to connect.
It seems my USB port on my laptop was buggy, after reboot I get following output via serial console:
U-Boot SPL 2022.07 (Sep 19 2022 - 13:20:08 +0200) Trying to boot from XIP

resetting ...
I get a Hard fault. I then tried an older version of u-boot using the information from https://github.com/fdu/STM32F746G-disco_Buildroot as a hint. With U-Boot 2018.11 I get a working binary (I had to disable Falcon mode):

Seems like a regression to me.
Yes, can you use git bisect to find it?
cd82f199852d88218e1f17f5ec07cdd9112a89c4 is the first bad commit.
I remember i encountered an issue with patch in the past and by updating my toolchain > everything goes fine.
Which toolchain version do you use ?
I used arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-eabi.tar.xz from ARM. https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
On my side i am using this one : https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/11.1.0/x86_64-gc...
Well it really seems to be an toolchain issue, with this one I can compile U-Boot master and it runs on the system without failure.
best regards Waldemar
