hello,

  

I am currently using the imx6ul-14X14-evk board, and I want to change the boot mode to "Boot From Fuses Mode".
I'm currently using NAND Flash boot. The Nandflash model is "MT29F32G08CBADBWP".
When I use SW602[1:2]= (ON, OFF) and SW601[1:4]= (ON, ON, OFF, ON), I can work normally.

 

Questions:
1. How can I modify eFuse to make the board work properly when using "Boot From Fuses Mode"?
I tried to set it up as follow ,but The chip doesn't seem to start,so how do I set it? Are these settings reversible?

fuse prog -y 0 0 00328033

fuse prog -y 0 5 000000A1

2. What is the difference between "fuse override" and "fuse prog" ?

Please help me,thank you!
