 # HJX9009 validated board profile
 
-This profile comes from the HJX-ADRV9009-X2 schematic and a PetaLinux 2018.1 hardware run. Reconfirm the PCB revision and live probes for every target; schematic constants do not replace target identity.
+This profile comes from the HJX-ADRV9009-X2 schematic and a PetaLinux 2018.1 hardware run. Reconfirm the PCB revision and live probes for every target; schematic constants do not replace target identity. Use [hjx9009-profile.json](hjx9009-profile.json), rather than this explanatory document, as the cache fingerprint's `--board-profile` input so editorial changes do not force a rebuild.
