Re: Building Freescale P2020RDB questions

Hi Matt,

 

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.

 

 

Best Regards,

 

Zhenhua

Subject: [meta-freescale] Building Freescale P2020RDB questions

 

Hi all,

 

I have successfully built the images for p2020rdb using the following sources and configuration:

 

  1. Poky tag “sumo-19.0.1” at git://git.yoctoproject.org/poky
  2. meta-freescale “sumo” branch commit hash: 407c6cf408969445031a492e2d25e0e2749582ea at git://git.yoctoproject.org/meta-freescale
  3. In local.conf, set MACHINE ?= "p2020rdb".
  4. 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:

  1. Did I get the recipes and configuration correctly? What did I miss to get a working u-boot image?
  2. 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!
