Hi all

 

My customer would like to reset the system using the WDT timeout reset.

However, they can't success.

 

In this situation, we have some questions about boot sequence of i.MX7D.

 

Q1

They don't input to POR at the time of WDT reset.

Do they have to input POR ? 

 

Q2.

According to the Figure 6-20 in IMX7DRM, there are some branch.

 

 

What is the criteria of "Check Reset Type" branch ?

In other word, what do you mean the "Normal" ?

 

Q3

In the "Download Initial boot Image(primary or secondary depending on persistent bit)" branch, what is the criteria ?

My understanding is only checking a vector table and persistent bit. Am I correct ?
