Hi team,


I would like to ask about NAND boot of i.MX257.

My customer is using NAND Flash for boot device of i.MX25 on their board.

Now they are using 512Mb NAND and they plan to change it to 1Gb.

For test, they change their software and tried to boot from 1Gb NAND. And the boot failed.

The datasheet of i.MX25 says that the NAND should have address-cycle=5 and # of Blocks=62 in the case of SLC NABD with 2KB pagesize.

The specification of the 1Gb NAND Flash the customer wants to use is 4 cycles.

The customer has a concern that i.MX25 may not support such NAND(address-cycle=4).

Is it true?

The NAND is Toshiba/ TC58NVG0S3HTAI0.

Could you tell me whether the NAND meets the requirement for i.MX25 boot device?
