AM335x NAND Flash Support

We are planning to use the below 8-Bit NAND flash from Micron for the booting operation.Could you please let me know,whether it is fine for the operation?

Datasheet:http://www.micron.com/parts/nand-flash/mass-storage/mt29f2g08abaeawp-it?matpart={EE128A07-9F44-48E0-A870-A288F09CCE70}

Size-2Gb

We are interfacing NAND Flash (8-bit) device with AM335x to write the U-boot and kernel images for the essential booting.we don't have any SD Card and USB option in our board.It is a small OEM board with some limited interfaces.So our primary booting image (kernel+u-boot) should be written to the NAND flash using JTAG during the boards first time powering.My doubt is,whether we can able to program and access the NAND Flash on a fresh board (during first time powering up) using JTAG device?

Thanks and regards

Hi,

Supported NAND devices must be either ONFI-compliant or listed in Table 26-14 in the AM335X TRM Rev. K. Please read the whole section 26.1.7.4 to understand how NAND boot works.

I suggest that you wire the SD card lines to a connector. And in production, you add a SD card to the board, and boot from SD card. This is a lot faster than JTAG, even for development. If you have bootet u-boot from SD card, you can write the NAND flash image from SD card into NAND with u-boot.
