So I'm getting some error during adding image in touchgfx Designer not any issue its generated the but when i build my main code its generated error likes TouchGFX_Framebuffer will not fit in region 'FLASH', makefile error and region overflowed by 134688 bytes. how to solve this error?

Hello @Furkan2 ,

This error means that the framebuffer requires more memory than you have memory available in your flash.

To solve this issue you have multiple solutions:

1. change your memory allocation to put your framebuffer in a bigger memory such as external SDRAM or inter SRAM (it is usually not recommended to use the flash for the framebuffer).
2. use a smaller framebuffer such as single framebuffer if you were using double or even partial framebuffer : https://support.touchgfx.com/docs/basic-concepts/framebuffer#framebuffer-strategies
3. optimize your code for size. Set your compiler to optimize for size and maybe you will be able to fit the framebuffer in your flash

 

I hope this helps!
