Hello Everyone,
I'm using an STM32L496 (1MB of flash) with an MT25QL128A external flash memory (16MB) for graphics assets in my TouchGFX application. I'm finding that I'm running out of code memory (the memory on board the STM32, not the memory on the external flash - that has plenty of room left). I've got all of my normal TouchGFX graphics assets (texts, fonts, graphics) going onto the external flash as per typical TouchGFX setup, but I've still at 93% usage on the STM's internal flash. I believe this is mostly due that high number of screens. Is there any way to move all or most of the GUI code (view and presenter code) into external memory as well?
