Hi guys, it's me.

In the morning when i started my project i saw mcu's memory area looks like SDram is not working and i asked if FLASH is full will mcu have data to ASSETS FLASH? And why don't we exploit the two together to increase their size?? 

touch gfx is quite new to me so i'm sure i'll ask a lot of questions and annoy you guys a lot, hope for your understanding  

This memory arrea show what is in linker script and your code destined to this sections.

For SDRAM in touchgfx exist two ways by address and by allocation.

Allocation need in linker script .... and will showwed right.

By address is direct hw and you see 0 use, but memory is used ok.

If your code plan use SDRAM too for other thinks , reservation need change in linker script or use by alloc....
