Hi,

What is the difference between P2020RDB_NAND and P2020RDB-PC_NAND. Can the image containing PC be run on P2020RDB target?

Version info for the board I'm using is as below

From U-Boot:

CPU0:  P2020E, Version: 2.0, (0x80ea0020)

Core:  E500, Version: 5.0, (0x80211050)

And from sticker at bottom side of board:

P2020RDB-PB REV B

Thanks,

Fahad

They target different board revisions.  If you have a -PB board then you need to use the P2020RDB_NAND target.

SDK 1.3.2 for QorIQ processors supports P2020RDB-PC board, is P2020RDB-PB obsolete? And what exactly is the difference between -PB and -PC boards, is it related to hardware or can firmware updates be used to upgrade to -PC?

Thanks,

Fahad

There are hardware differences between PB and PC, PC fixes some erratas of PB and improved in layout.

For example, the PB board supports DDR2 and the PC board has been designed to support DDR3.
