[Discuss OpenCPI] New RCC platform issues (no available containers)

Hello,



A week or two ago you guys were helping me get an SD card created using a new RCC platform spec. That has been successful, and it seems that cross-compilation etc. worked correctly as I am now running commands on my board and getting OpenCPI output (errors/logs). I am now running into a couple more errors.


First I will note that I am not booting my board from the SD card. I am just using the opencpi file tree created by the 'make deploy' command.


When I run the setup script on my board, I get the following error message:


[root_at_asdr-24 opencpi]# . ./default_mysetup.sh
Discovering available containers...
Exiting for exception: Error processing system configuration file "/mnt/card/opencpi/system.xml": error loading the "rcc" "container" dri
ver from "/mnt/card/opencpi/brik2/lib/libocpi_rcc_s.so": error loading "/mnt/card/opencpi/brik2/lib/libocpi_rcc_s.so": /mnt/card/opencpi/
brik2/lib/libocpi_rcc_s.so: internal error
%


'libocpi_rcc_s.so' exists in the location specified. Perhaps someone could elaborate on what 'internal error' might mean?


I noticed that if I edit 'system.xml' and comment out everything between the <opencpi></opencpi> tags, I seem to get a step further but then it fails because it can't find any containers. Here is the message I get when I try that:

The 'system.xml' I'm using is the same one produced when building an SD card for a ZedBoard (as my board is very similar). I'm just not sure what I need to do to make a container available so I can run a test application.


Thanks in advance,
