LCDIF and Internal RAM

giannigrondona — Thu, 17 Jan 2019 20:50:41 GMT

I intend to use mxrt1062 microprocessor with about 1 Megabyte of internal RAM. I'd like to put frame buffer in internal RAM ( no SDRAM). Is it possible? How about cache setting for internal RAM?

Best Regards

Thank you for your answer. I am going to use OCRAM per video Buffer. I think I have to set cache policy for OCRAM in this manner:

CACHE ENABLED
WRITE THROUGH

Is it correct?

Thank you

Best Regards

Hello.

You are welcome. Usually the memory cache of the video frame buffer is disabled. And for the detail information,you can refer to the configuration of the last memory region that the board.c of any example of the SDK.
