Other Parts Discussed in Thread: TMS320DM368

Hi guys i need info about two NAND devices from Micron:

MT29F1G08ABADAH4-IT

MT29F2G08ABAEAH4-IT

I'm planning to replace my old numonyx NAND NAND01GW3B2C with one of the two devices mentioned above.

I tried on my custom board (based on DM368) to use these devices but with no luck. the flash isn't accessible neither with debugger like Lauterbach while with the old Flash everything was fine.

I'm suspecting some troubles occurs during replacing of the chip but i'm not so sure...I need to investigate on these point.

In the meanwhile i'm asking to you guys if someone used successfully these P/N from micron with TMS320DM368 (i need to know if booting from NAND with these devices works fine!

thank you all!

Maybe i've found the problem..

Some balls of the BGA of the numonyx NAND which were previously labelled as NC (but in my design connected to GND) become DNU on the Micron's NAND... One ball is bonded to the chip NAND_INIT and i think that grounding this signal it's definitevely a bad idea!!!

I'm gonna try to rework my boards and let you know if everithing goes well with those pins unconnected!!

Hi Luca,

Does your replacement of numonyx NAND01GW3B2C with MT29F1G08ABADAH4-IT/MT29F2G08ABAEAH4-IT worked or not?

Please reply so that I can also try the same replacement.

Regards,

Prashant

Hi Prashant,

both NAND from Micron works fine for me..

Just check that in your design the pins labelled as NC, in numonyx flash are left unconnected to have full compatibility with micron devices..

Bye!
