Can not write to spi nor flash in Linux on IMX6 solo

Hi,

 

We have a customized board with IMX6 solo which use 64M Micron n25q512a nor flash.

 

We are using almost same pin assignment in SPI Nor flash part as Sabre AI board.

Spi nor flash Erasing/Reading/Writing command works properly in Uboot.

 

But In Linux, I can erase and read from this Nor Flash, but I can not write anything to it.

The write enable is on and I have changed pin assignment and other things in Device Tree.

 

Is there anything I missed to make writing work?

 

Thanks and Best Regards,

Ivy
