Hi all,

MXRT1050\1052

I'm sorry if this question was asked before, couldn't find the answer .

What should be set in the SDK to avoid using external RAM?

 

Thanks,

Adi

Hi @adi2Intel ,

   If you don't want to use the external SDRAM, and you are using the SDK code for RT1050\2, it is very easy, just set:

XIP_BOOT_HEADER_DCD_ENABLE=0

And delete the SDRAM memory from 0X80000000

Wish it helps you!

If you still have questions about it, please kindly let me know.

Best Regards,

Kerry

I was just wondering how we know what defines to use in this? Is there documentation that tells what they are and what they do?
