1. I am working on a project with STM32F469I-Disco board. I am trying to read and write to Quad SPI memory. I have followed all the steps given in Application Notes 4760 and also steps given for Framebuffer in External RAM from TouchGFX documentation.

Even after that I am getting "?????? " from memory address 0x90000000 in memomy browser from STM32Cube IDE. What does that tells?

Can you please guide me in a right direction?

How did you create this project?

Hi Martin,

I created a project in STM32CubeMX :

Toolchain/ IDE: STM32CubeIDE

Board used: STM32F469I-Discovery Board with default settings.

I was trying to step through the How To guide for bringing up a board in the TouchGFX documentation. During "Step 6. External Addressable Flash" I ran into an issue with Hard fault and I was getting "????????" at address 0x90000000 up until the point it was configured.

Thanks to @Community member​ ​ He Suggested I go through the BSP code for the STM32F469I-DISCO to set up the QSPI suitably. This resolved my issue with the hard fault.

I then loaded the external linker and got the QSPI in build analyzer.

Thank you!
