unable to complete build of project STM32H7B3I-DK

[Arno1]

I'm trying to build the SBSFU project for board STM32H7B3I-DK (2_Images_ExtFlash) but am unable to. Everything does build fine but it fails on the last step, the postbuild.sh step, at prepareimage.py enc.

I'm using STM32CubeIDE 1.5.1 on Linux

This is the error I get:

(some paths truncated)

There is no nonce.bin in Projects/STM32H7B3I-DK/Applications/2_Images_ExtFlash/2_Images_SECoreBin/Binary but after adding the one from 2_Images (without ExtFlash) I get the same error.

Best regards,

Hello Arno,

I tried to reproduce the issue on a Ubuntu 16.04 LTS with same version of STM32CubeIDE.

I could see 2 issued while building the loader:

1- Need to change '\' by '/' in the ld file path in the properties

2- Need to activate the VFP also in properties

After that all when well until UserApp build.

One possible reason for your issue is the too long path where the package is installed.

Best regards

Jocelyn
