TiOS Monitor/Loader Update

Our ARM-based Tibbo BASIC/C-programmable devices — EM2000, EM2001, TPP2(G2), and TPP3(G2) — support over-the-air (OTA) firmware updates*.

Two things are required for OTA updates to work:

  • Your device (EM2000, EM2001, TPP2(G2), or TPP3(G2)) must be equipped with the WA2000 Wi-Fi/BLE add-on module;
  • Your device must have the Monitor/Loader V3.00B (or a later version)**.

The Monitor/Loader (M/L) is a resident firmware that is present on all Tibbo devices. The M/L V3.00B added support for Bluetooth Low Energy (BLE) OTA firmware updates. Many EM2000, TPP2(G2), and TPP3(G2) devices in the field were shipped prior to the release of the M/L V3.00B. To enjoy OTA firmware updates, you will need to update the M/L of your ARM-based Tibbo device as described below.

* OTA firmware update procedure is described in our TIDE, TiOS, Tibbo BASIC and Tibbo C Manual.
** "B" indicates that the M/L is BLE-enabled.

Checking the current version of your Monitor/Loader

  • Power up your device while keeping the MD button pressed — this will boot your device into the M/L.
  • Release the MD button.
  • Make sure the Ethernet cable is plugged in and the yellow Link LED has turned on.
  • Launch the Device Explorer (it is a part of Tibbo IDE software).
  • Check the current M/L version of your device. If it isn't at least V3.00B then the M/L is in need of an upgrade.

Upgrading the Monitor/Loader

  • In the Device Explorer, choose Upload, then Load Firmware Through the Network to upload a M/L upgrade app into your EM2000, TPP2(G2), or TPP3(G2):
  • After the file upload completes, your device will reboot and start executing this file.
  • Wait until the green status LED is turned on. This will indicate that the upgrader app is ready to update the M/L.
  • Press the MD button (pull the MD line low) — red and green status LEDs will turn on. The upgrade has begun!
  • Once the upgrade completes the device will reboot.
  • You can now verify that your device's M/L version shows as V3.00B (you may need to hit Refresh to rescan the network).
