opkg list-installed | grep dx80 dpkg -l | grep syn213 Expected output should show a package like dx80-firmware-ce820-syn213-relpkg with version ending in _fixed . journalctl -u dx80-controller --since "5 minutes ago" |
journalctl -u dx80-controller --since "5 minutes ago" | grep "fixed" A persistently fixed system will show the message at boot during package validation, and never again until the next update. When You Cannot Fix It Yourself: Vendor Lock-In Some industrial controllers cryptographically sign brelpkg bundles. In those cases, dx80ce820syn213brelpkg fixed is a verification token that only appears after a licensed technician applies a vendor-provided .bin via JTAG or a proprietary flashing tool (e.g., CodeWarrior or IAR). CodeWarrior or IAR).
