Prevent external SRAM use

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

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?
