Hi all

 

I'm testing a SD/MMC manufacture boot flow with MCIMX6ULL-EVK.

In my understanding, when I set SW602 to ON, OFF and witch SW601 to OFF, OFF, ON, OFF without microSD card, I can test a following flow.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


However, it seems that it's not into USB download mode.

My confirmation way is using MFGTool.

When I tested with MFGTool, the MFGTool windows shows "No Device Connected”.

So I judged it's not in USB download mode.

 

On the other hand, I tested same way with MCIMX7SABRE.

It can detect a device.

 

With a above result, something is wrong with SD/MMC manufacture boot flow for i.MX6ULL.

Is there any information about the error of SD/MMC manufacture boot flow for i.MX6ULL ?

Or please tell me how to check the SD/MMC manufacture boot flow for i.MX6ULL.
