imx6ULL EVK flash memory settings

Dear community, I solder a NAND flash module on the imx6ull EVK.

The flash module is the MT29F4G08ABADAWP (the 4Gb IT) from MICRON, I attach the data sheet.

After solder the module we use the mfgtools2, but unfortunately I am unable to see the module and there is no way to interact with it. Of course I try with the u-boot with NAND support, but the NAND field report 0MB and no one operation like "nand info" are working on my side.

 

I found a document that explain how to setup some resistors on CU module to enable the NAND flash, you can see this document at page 9 of the attached pdf file.

 

My thoughts are to set the BOOT_CFG1 in this way:

bit set
0 1
1 0
2 0
3 0
4 1
5 0
6 0
7 1
and to set BOOT_CFG2 in this way:
bit set
0 0
1 0
2 0
3 0
4 0
5 0
6 0
7 1

 

I have no concern about BOOT_CFG4, because I don't clearly understand how it works and how it could help to setup the NAND communication.

 

Can anyone confirm my setup for BOOT_CFG1, BOOT_CFG2 and BOOT_CFG4?

Is this the reason that I am unable to see the NAND flash from u-boot?

 

Any help will be appreciated,

Stefano.
