Hi Igor,
thank you for your prompt reply.
I apologize for the long post, but I am unable to find how to attach a file in the reply.
So could it be the wrong resistor layout?
Here you can find a picture of my module.
In the mfg-tool I am running the mfgtool2-yocto-mx-evk-nand.vbs and here you can find the log:

The last part of the log is quite clear, the kernel can't see the /dev/mtd0 device.
The flash is brand new, so I suppose that is not formatted, but I don't know how to do this.
I want to remark the flash part number Micron 29F4G08ABADA.
Thank you for your help.
Best regards,
Stefano.
