I am trying to interface STM32U5G7VJT6 with MT25QL128A using OCTOSPI1 in Quad SPI mode, but I still cannot store/run TouchGFX assets from external flash memory.
Current configuration:
Screenshot attached.
Could someone please check if I missed any important configuration like memory-mapped mode, linker settings, TouchGFX asset location, BSP/init sequence, or MT25QL128A command setup?

Hello @Furkan2;
--> Screenshot attached.
Could you please add the screenshot.
Can you do read and write operations on the external flash memory?
I recommend you to look at AN5050 section "7 OCTOSPI application examples" may help you.
Thank you.

Thank you for your response.
I have attached the OCTOSPI1 configuration screenshots and related settings.
Currently, I am not able to MT25QL128A external flash memory, so TouchGFX assets are also not working from external flash.
I will also check AN5050 section 7 as suggested.
