66AK2H14: SoC based custom design with MT29F1G08ABBFAH4-ITE:F NAND flash

Andranik,

The EMIF16 module of 66AK2H14 supports the following:-

• 1-bit ECC for 8-bit and 16-bit NAND Flash (Does not support error correction)

• 4-bit ECC for 8-bit and 16-bit NAND Flash (Does not support error correction)

But it doesnot support 8-bit ECC.

Is it safe to disable the controller’s ECC completely and rely only on internal 8-bit ECC ?

Not sure. Give it a try.

Please check for options to diable the ECC.

For example,  In the NAND boot parameter table ( section 10.1.2.5.9 in the datasheet ) , there is an option like

• 0 = NAND Device is a non clear NAND and requires ECC

• 1 = NAND is a clear NAND and doesn.t need ECC.

In page no: 29, SECTION : -  ECC Support in https://www.ti.com/lit/ug/sprugz3a/sprugz3a.pdf

1-bit ECC calculation for NAND device connected to a specific chip select is set off by writing a ‘1’ to the CSN_ECC_START bit of the NAND Flash Control Register (NANDFCR)

----> try not setting as '1'. And give it a try...

Now the question is what the NAND flash datasheet actually means?

NAND flash datasheet means, the datasheet released by "Micron technology " for their NAND part, "MT29F1G08ABBFAH4-ITE:F"

For example, in this link, the datasheet of the NAND memory, you mentioned, seems to be given.

https://www.mouser.in/ProductDetail/Micron/MT29F1G08ABBFAH4-ITEF-TR?qs=j%252B1pi9TdxUYUdQHmeJpnzg%3D%3D

or

once you register in Micron website, you can download the datasheet.

I have attached here one which is integrated in K2H EVM. 8662.m60a_4gb_8gb_16gb_ecc_nand.pdf

For design support, as Ralph already pointed, it is better to approach the third party like advantech.
