Hi all,
I'm having some questions, please read on.
I would like to interface a NAND flash with the IMX53, when using the IO-MUX_tool I get the recommendation of connecting this NAND-flash to the PATA_DATA_xx pins , but while looking in the KERNEL-sources 2.6.35.x 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.
Is there any particular reason for this ?
Anyone succeeded in booting the IMX53 from NAND?
If so, I wonder if you have a 'tool' to create a valid NAND-flash-image (ref to NAND-FCB and NAND-DBBT format, page 500/501 ref manual).
Is there a known-working u-boot that boots from NAND, and that has USB support as well?
Is there any one that has a 'FUSE-tool' that allows me to blow-efuses, that is relative safe?
Because I see, that may of you have been having troubles (which means breaking boards) while 'expirimenting' with efuses.
Thank You,
Noel

Look here for some info on ubifs for NAND and fuse blowing examples:

We are booting the iMX53 over NAND. We are using an 8 bit 2Gb part from Micron and the data bus is connected to the pata_data{0..7}. From a tool side, I am not sure how the software guy did it. But I do know that there was some flaws in small block NAND u-boot and kernel support and we were working our way through that when we decided to go the 2Gb part.

Yes Noel,
Better not go for eFUSES, They are only useful, when the product is on mass production.
Cannot comment on NAND usage.
