How to connect SLC NAND flash memory to i.MX6Q port for booting

Dear Sir or Madam,

I want to design a image process board with i.MX6Q.

So I bought a SABRE Board for Smart Devices (MXIMX6Q-SDB) reference board from freescale.

This reference board has a 8Gb eMMC iNAND device which have 0.5mm pitch ball package.

Our board circuit designer want to use 0.8mm pitch package and  I think eMMC device is expensive than SLC NAND flash memory.

So, I want to use slc nand flash as like Micron MT29F8G08ABACAH4...(8Gb, x8, 68-ball VFBGA, 0.8mm pitch, please check attached file ).

But I can't find any schematic i.MX6Q & SLC NAND flash memory.

NAND flash have ALE, CE#, CLE, LOCK, RE#, WE#, I/O[7:0], R/B# signals.

I want to use how to connect these signals to i.MX6Q port( for example, ALE <->NANDF_ALE)

Let me know about it.

Best regards.

Young,

When connecting the i.MX 6Q to Raw NAND, the pin connections are very straight forward:

NANDF_D0 (A18) => I/O[0]

NANDF_D1 (C17) => I/O[1]

NANDF_D2 (F16) => I/O[2]

NANDF_D3 (D17) => I/O[3]

NANDF_D4 (A19) => I/O[4]

NANDF_D5 (B18) => I/O[5]

NANDF_D6 (E17) => I/O[6]

NANDF_D7 (C18) => I/O[7]

NANDF_ALE (A16) => ALE

NANDF_CLE (C15) => CLE

SD4_CLK (E16) => WE#

SD4_CMD (B17) => RE#

NANDF_CS0 (F15) => CE#   (Use additional CSn for additional chip selects if needed)

NAND_RB0 (B16) => R/B#     (Connect RB0 to R/B# pins off all chips. Not necessary to have RB1 - RB3)

NANDF_WP# (E15) => WP#

Use any GPIO pin to service LOCK function if desired. We do not have an  example that uses this feature since we have not used 1.8V NANDF before.

I am attaching a document with the schematic connections used on our internal validation board. Ignore the connections to Portn, as they do not apply to the NANDF use case.

Cheers,

Mark
