P2020RDB and P2020RDB-PC are different board revisions, there are hardware differences between the two revision, e.g. P2020RDB supports DDR2 and P2020RDB-PC is designed to support DDR3. The latest meta-freescale only supports P2020RDB-PC.

Hi all,
I have successfully built the images for p2020rdb using the following sources and configuration:
Poky tag “sumo-19.0.1” at git://git.yoctoproject.org/poky
meta-freescale “sumo” branch commit hash:
407c6cf408969445031a492e2d25e0e2749582ea at git://git.yoctoproject.org/meta-freescale
In local.conf, set MACHINE ?= "p2020rdb".
Flashed u-boot image: u-boot-nor-2018.03+fslgit-r0.bin on the NOR flash location 0xeff40000.
However, when the device starts, the serial console does not display anything. So here are the questions:
Did I get the recipes and configuration correctly? What did I miss to get a working u-boot image?
I noticed the configuration is for a board called p2020rdb-PC. I have an old Freescale development board called “p2020rdb”. Are they the same? If not, what do I need to modify to support this legacy board?
Hope I can get help here. Thank you very much for your help!
