Allocate a static memory for Embedded Wizard for display

[JohnCC]

Hi,

      I use embedded wizard tool to handle display graphic and I need allocate a RAM buffer for it. I need to write frame buffer ram start and size in embedded wizard config header file.

My question is

How can I allocate a static ram buffer for it? And I need to know ram start address and size. Of course it's the same address every time

I use SDK 17 and IAR for compiler. 

I have one idea is I change RAM_START from 20002798 to 20012798. So, I reverse 0x10000 ram size that I can use. I can write ram start address is 20002798 to embedded wizard config header file and size is 64Kbyte.

Is there something wrong with me?

Thank you.

John.

Hello,

There is no need to change the RAM start and size size(s). 

Instead you should be able to static allocate specific buffers to specific address(es) in RAM like doing something like shown in this thread (it's a little bit different use case, but the intention in both cases is that you want specific RAM to be allocate for specific purpose):
Restricted regions in RAM
