Hello,
Step 7 has a description of DDR Remove the core reset.
I thought this control would control the DDRC_CORE_RST Field.
However, at the URL below, I found that there is a PATCH that controls DDRC_CORE_RST Field and DDRC_PRST Field.
Do I have to reflect the processing described in PATCH in the source code?

Solved! Go to Solution.
table 9-11 is for Power Removal, the patch is for Re-enabling the power, if you need to re-enable the power, you need to use the patch
where is step7? could you share with me?"I thought this control would control the DDRC_CORE_RST Field." what "this control" do you mean?
This is the leftmost Step column in Table 9-11.
I thought that the following Description can be processed by setting DDRC_CORE_RST Field.
Excerpt from Step 7 Description
Remove the core reset core_ddrc_rstn = 1’b1
aresetn_n = 1’b1
