NAND over PATA_DATA_xx ?

Hi all,

 

I've been digging into sample code and schematics for the iMX53 for some days now.

 

I'm missing something, the the IO-MUX_tool recommends the connection of a NAND-flash to the PATA_DATA_xx pins, but while looking in the KERNEL-sources 2.6.35.x and UBOOT-sources.

 

There seems to be none of the eval-boards that has the NAND connected to the PATA_DATA_xx pins but in stead of PATA_DATA_xx but EIM_DAxx used.

 

It seems that all de definitions of the IOMULTIPLXER for PATA_DATA_xx are missing, or I'm I really looking over something ?

Anyone .. that has a board booting from NAND over PATA_DATA_xx that is willing to share some details / sample code ?

 

 

Kind regards Noel.

Hi

 If you want to find those setting either for EIM_DATA or PATA_DATA you have to correlate the GPIO settings that are available in the MUX Code.

Hi  Krishna Pavan

I'm looking into EVK for i.MX53 that supports NAND... But also on this board NAND connected to EIM_DAxx and not to PATA_DATA_xx.

Also no definitions for PATA_DATA_xx pins in the MUX code ????

This is what worries me.

Regards Noel

Hi Noel,

Just check, if EVK for i.MX53 supports/has NAND, because, i.MX51 doesnot have a NAND Flash.
