I've got the same issue here with an STM32H7A3. I need to enable the Quad configuration because otherwise proper codegen with FileX/LevelX will not work.
A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
Also facing this issue with STM32CubeIDE 1.19.0 and am wondering if there's an update on this. I'd like to be able to use CubeMX code generation for this as opposed to manually configuring it. If not, did any of you find workarounds?
