Error code 65700 occurred during engine initialization preventing execution

Go to solution

I have inherited a rather large project which had several issues that lead to some instability. The first issue resolution was to move the SVE to the real-time target and off the Windows PC. I have been using RT and FPGA for years and I am very comfortable with setting up and deploying projects. However this project uses DCAF to write to the Linux shared memory as a majority to this deployment runs on C code built years ago. 


None of the hardware has changed, none of the software has changed, none of the I/O mapping has changed. The current DCAF configuration file is mapped to an alias called "sve_host" with an entry in the /etc/hosts file for the Windows PC hosting the SVE. To keep things super simple I updated the /etc/hosts/ file to add the alias "sve_host" tot he localhost alias for I tried this approach to eliminate the need to edit close to a hundred variables in the configuration file.


I have rebuilt the project, deployed the variables, deployed the DCAF configuration and I get the following error in the /var/log/messages file, but cannot find any supporting documentation.

You could see if anyone in the DCAF forum can help with this issue:


The errors seem related to the DCAF engine.
