20 Appendix  
20.1 Setting up an Upgrade Server for OTA via RGAS  
Implementing an "upgrade server" for the cabin router SystemX software is as simple as serving a json file  
from a known path (/feeds/erouter_rootfs.json) with the following fields:  
file - string - the url of where the .upgrade release file will be served from  
bytes - integer - size of the .upgrade release file in bytes  
build - string - an ISO8601 time for the build  
version - string - semver style version number for upgrade release.  
checksum - string - sha256 checksum of the .upgrade release file.  
notes - string - url for release notes file (typically .pdf)  
The "build" timestamp field is used by the SystemX system to determine if the upgrade file is "newer" than  
the currently loaded version.  
The "version" string is display only - it is not checked against the file, nor used for determining if the version  
is already installed.  
This service only supports having one "live" version at a time - it is not possible to have multiple .upgrade  
files available at the same time. For testing purposes, it is recommended to set up a separate server (on a  
separate hostname, as the url path is not changeable) and update a single router to point at this new  
"testing" server.  
Example:  
{
"file": "https://ccx.support/upgrades/systemx-erouter_rootfs-1.8.1.2-APR11-06.57.50-2023.upgrade",  
"bytes":259573883,  
"build":"2023-04-11T06:57:50",  
"version":"1.8.1.2",  
"checksum":"3192d5df1cda02381b3e49b866526d78c8fb57642e2a71a04b652d3fa7f07193",  
"notes":"https://ccx.support/notes/CRN-0054.a.pdf"  
}
