Hi, everyone,

 

I am trying to use BF609 Inter core communication. The BF609 cpu core A run uClinux, and I want to run software audio  echo cancel module on BF609 cpu core B. I find some info about ICC(https://docs.blackfin.uclinux.org/doku.php?id=protocols:icc).there is  example code about how to use ICC but the web link is not work now.

I confire kernerl with icc support and make it ,It's ok. when I configure ICC in buildroot like below and make it .there is error info about can not find the icc-10740.tar.gz. I also can not find the icc-10740.tar.gz by google.

Configure ICC in buildroot:

Package Selection for the target  --->

     Miscellaneous  --->

          [*] bfin inter-core communication support ICC

           cpu type (BF609)  --->


1. how to find the packet.c  and task1.c file or other example code  about how to use the iCC ?

     2. How to find the icc-10740.tar.gz or finish build icc utils and test suites?

 

  Thanks.
