RT1020 - What address spaces are available to the DCD?

Document: i.MX RT1020 Processor Reference Manual, Rev. 1, 12/2018

Section: 8.2 Overview

Page: 187

It says: "The DCD is restricted to the memory areas and peripheral addresses that are considered essential for the boot purposes (see Write data command)."

So I followed the link to here:

Section: 8.7.2.1 Write data command

Page: 248

The NOTE at the end of this subsection says: "The list of allowable blocks and target addresses for the chip are provided below".

I can't find the list of allowable addresses (for the DCD). The table is missing.

The reference manual for the RT1050 does have a table after the equivalent NOTE (Table 9-42. Valid DCD address ranges).

Can I assume the address ranges are the same for the RT1020?

Many thanks.

Hi rshipman,

Yes, the address range is same. RT1020 is a shrink version of RT1050. I'll report this document error.

Regards,

Jing
