2008-04-25 04:13:53     NAND notBusy for BF-54x

mentions not to use Blackfin's ARDY (but a GPIO_PFx)

I'm sure this goes for the BF-53x which do not have the on-board

NAND Flash Controller (NFC).


For BF-54x a NAND chip can simply be connected to the NFC and thus to

the NFC_NANDRB without any problems.

The uClinux NFC driver () requires no changes/adaptations then.


I this right ?

Exactly - the page you are referring to talks about connecting NAND flashes without dedicated NFC.

On BF548 and BF527 you would use the NFC.

For a example connection see the BF548 EZkit Manual Schematics.
