Firmware Version 5.0.1 bietet gegenüber Version 3.1.11 eine modernere Benutzeroberfläche, höhere Sicherheit, verbesserte Stabilität sowie erweiterte Funktionen für Wartung und Entwicklung. Dadurch lässt sich der TXT 4.0 sowohl im Bildungsbereich als auch in professionellen Anwendungen zuverlässiger, effizienter und komfortabler einsetzen.

Mehr Sicherheit und Stabilität

• Aktuelle Sicherheitsupdates für Linux, OpenSSL und zahlreiche Systemkomponenten
• Erhöhter Schutz durch zusätzliche Sicherheitsmechanismen und Systemhärtungen

Moderne Entwicklungsumgebung

• Python 3.12 für bessere Performance und aktuelle Sprachfunktionen
• Node-RED 4.1.8 mit neuen Funktionen und Erweiterungen
• Neue Entwicklerseite (/developer) mit Dokumentationen, Vorlagen und erweitertem Remote-Debugging

Mehr Komfort im täglichen Einsatz

• Browserbasiertes Screensharing ohne zusätzliche Software
• Integriertes Web-Terminal für den direkten SSH-Zugriff

Hinweis: Für die Aktualisierung auf Firmware 5.0.1 muss Firmware 3.1.11 bereits installiert sein. Zusätzlich wird für den Update-Prozess eine MicroSD-Karte benötigt.

Firmware 5.0.1

• Web server / Web UI
  • Refreshed the TxtWebserver look & feel and moved web services into TxtWebserver.
  • Added a new firmware update overview page and improved the firmware update flow (including better error/log handling).
  • Improved the Web Explorer (layout fixes, bug fixes) and fixed the download button in the TxtWebserver explorer.
  • Added dedicated service pages:
  • Added developer docs at /developer or /#developer (Python, C, C++), plus templates and improved remote debugging via debugpy.
  • Stabilized WebTerm; ensured Node-RED is reachable via /nodered and the dashboard via /ui.
  • Improved web joystick stability/compatibility (waitress/socket.io, forced threading mode) and better behavior in WLAN client mode.

• Backup / Restore / Reset to Defaults
  • Extended and hardened backup/restore (dialogs re-added/reworked, consistent media requirement checks, more robust behavior during GUI restarts).
  • Hardened “reset to defaults” (timeouts, signal/dialog fixes, layout fixes).
  • Improved SD-image / restore UX with progress dialogs/overlays; added tolerance for 4GB SD cards.
  • Added user partition repair capabilities:
    • New txt_repair_userfs utility to scan/repair userfs and restore required files/permissions
    • New HMI button and a sudoers whitelist for ftgui to execute the repair command

• Hardening & stability
  • Updated and hardened Avahi / ZeroConf / Bonjour.
  • Hardened Python path discovery.
  • Improved USB stick detection for backups (prefer mountpoints under /opt/ft/workspaces/ext_usb/*).
  • Fixed permissions/ownership issues (e.g., dav_users, ft:www-data).
  • Fixed U-Boot LED behavior.
  • Improved hostname reload behavior (when accessed via txt40.local or IP, reload using txt40-<name>.local).
  • Added an “unsecure password” warning.

• Build / CI / security
  • Integrated and fixed Trivy scanning.
  • Made CVE checks more resilient (handle NVD API rate limiting, warn on missing API key instead of failing; faster with API key).
  • Hardened the pipeline by encrypting critical deployment certificates and Nexus configuration; added preparation work for security assessment.

• Platform / base updates
  • Updated Yocto/Scarthgap with multiple security and package fixes (including OpenSSL/tzdata updates and various CVE fixes).
  • Updated the Linux kernel within the 5.10 line (ST r2.3 base with KTN-specific commits).
  • Updated meta-openembedded.

• Component updates (latest versions referenced in the changelog)
  • TXTAPI: 6.5.1

• New tools & features
  • Added txt_util (read status values) and txttop (terminal status utility for peripherals).
  • Added volume control.
  • Moved external MQTT broker port from 1883 → 3883 (internal port remains separate).

  • Added a reboot dialog.
  • Fixed developer examples.

Der TXT Controller (Vorläufer des TXT 4.0 Controller) kann nicht mit der ROBO Pro Coding App programmiert werden, weil dieser in dieser App nicht unterstützt wird. Bitte verwenden Sie die ROBO Pro Software unter Windows für den TXT Controller.
Die ROBO Pro Software kann über den Button heruntergeladen werden:

Download

Bitte installieren Sie die TXT 4.0 Controller Firmware neu, indem Sie folgende Anleitung befolgen:
