AM625: GPMC NAND support

Hello GR,

GR said:

I think all of EVM that provided by TI does not have parallel NAND memory on EVMs.

Is there anything to EVM (including 3rd party board) can test GPMC? (Best is taht parallel NAND memory is on the board) 

Yes, you are correct. There is no NAND device mounted on EVM's.

At TI, we have some external daughter cards with modifications PCB which connected to AM62X devices.

But, these daughter cards can't be used by customers directly.

We recently created external daughter cards for AM64X devices which are compatible with AM64X EVM's and not with AM62X devices.

I can confirm with team about this and let you know

I think there is 2 type usecase of NAND memory, booting memory and strage memory.

I think booting memory is only 8-bit bus ONFI 1.0 NAND memory.

Yes, you are correct in booting needs 8bit NAND memory.

In Application, you can use it till 16bit.

GR said:

 Could you let me know tested part number of NAND flash for strage?

 (I believe API for GPMC is tested)

Yes, we have tested and we are using the part number below.

We are using 8-bit NAND memory.

NAND Flash Memory
MT29F2G08AABWP/MT29F2G16AABWP
MT29F4G08BABWP/MT29F4G16BABWP
MT29F8G08FABWP

Hello GR,

Currently, we have an AM62X NAND memory interface card and users can't connect directly to AM62X devices and users need to do some PCB modifications on the NAND interface card. So, as of now, we don't have any plans to support this a daughter card on AM62X, but I have posted reply to Hw team as well.

If I get any details I will post to you.

Regards,

Anil.

Hello GR,

Internally discussed with Team and confirmed that TI does not provide any GPMC external interface cards to test GPMC.

Users need to make their own GPMC external interface card to test with AM62X or AM64X.

Third parties also do not provide these boards.

Anil.
