Hi all

 

 

There is a MBR option for boot of i.MX7 in reference manual of Figure 6-38.

But there is little explanation for MBR option.

http://www.nxp.com/docs/en/reference-manual/IMX7DRM.pdf

 

 

Q1.

Is there any hardware setting bit for MBR option ?

 

Q2.

If Q1 is yes, which bit does user set ?

 

Q3.

If Q1 is no, I think user set by their software, do you have any example for set it ?

 

Q4.

When user doesn't use the option, do we need to set 0x00 to MBR region ?

 

Q5.

In case of user doesn't use the option, if undefined values are written in the MBR area, will there be any difference in behavior after booting ?

 

 

Please contact me if it's lack of info.
