How to update the yaml architecture configuration
...
in the IOC
The YAML Architecture Configuration (YAC) is a set of text files that defines the registers supported by the hardware. It is typically delivered by the hardware engineer as a gzipped tar file containing one subdirectory.
...
- Remove the existing YAC subdirectory from ${TOP}/yaml, or arrange to use new subdirectory name.
- Untar the YAC file under ${TOP}/yaml.
- In the IOC startup script st.cmd, update the 2nd parameter of YCPSWASYNConfig() to point to the 000TopLevel.yaml file within the YAC.
For example, "yaml/AmcCarrierBcm_project.yaml/000TopLevel.yaml".
