AM6412: NAND Flash

Part Number: AM6412

Can we connect the following parallel NAND devices to the GPMC interface?

- MX30LF1G28AD-XKI(68-BGA package)

- MT29F1G08ABAEAWP:E

There is a requirement for NAND interface inside the datasheet:

AM64x ROM only supports boot from ONFI 1.0 compatible 8 bit parallel NAND memory up to 2Gbytes in size connected to GPMC CS0 with the following geometries:
• 2Kbyte page and spare area of at least 64 bytes or
• 4Kbyte page size and spare area of at least 128 bytes.

We want to make sure if we are meeting the requirement with the selected NAND devices.

I'm looping in HW teams for inputs.

Hello Dashan,

Thank you for the query.

The page size requirements seems to match the requirements mentioned in the TRM

MX30LF1G28AD-XKI(68-BGA package)

- Page size: (2048+128) byte for 1Gb/2Gb (4096+256) byte for 4Gb

MT29F1G08ABAEAWP:E

• Organization – Page size x8: 2112 bytes (2048 + 64 bytes)

For timing related information, please refer to the below section of the datasheet.

7.10.5.8.3 GPMC and NAND Flash — Asynchronous Mode

Hello Darshan,

Please refer to the below E2E thread regarding the nand flash support.

(23) AM6412: Can this device talk to both 8 bit NAND FLASH and a T1 Framer using the GPMC port? - Processors forum - Processors - TI E2E support forums

In case you cannot access, below is sumary

The way I understand it is that they don’t say specifically that the processor doesn’t support boot from NAND, but that they can’t verify it since the EVK doesn’t have one.

According to the datasheet and reference manual, it seems that it does support it (unless the datasheet in incorrect). section 4.3.14.

Yes, your understanding is correct. NAND support on AM64x is not validated, so TI doesn't provide technical support regarding to GPMC/NAND

Hi Kallikupa,

Based on this thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/991738/processor-sdk-am64x-processors-forum

It say's - "Processor SDK Linux for AM64x doesn't support GPMC, so you cannot use NAND via GPMC on your design if you use Linux."

This is 1year old thread (so many changes would have happen so far and hence),

Do we have SDK for GPMC now? Does AM6412 support NAND on GPMC interface?

Does AM6412 support NAND on any other interface?

Thanks,
Darshan

Hello Darshan,

Thank you for the note.

I am not aware of any change to the SDK supporting Nand flash.

Our nand flash expert is on vacation. I can check with him and update. Please expect a delayed response.
