Have a custom device based on the i.MX6Q processor and have some problem with booting up from SPI-NOR flash.

Using the same file of u-boot.bin burn to SD card,eMMC and SPI-NOR flash.

It can booting up from SD card and eMMC successfully.

But boot up from SPI-NOR flash, when I use the command of "print".

There is no environment variable.

SPI-NOR flash connect to SPI3.The chip select is cs0.

I burn the u-boot image to SPI-NOR flash by MfgTool.

Does someone know  what is the problem may be?

Do I need to config the pin of SPI3 no the code of u-boot?

What can I have a try?
