Ethernet Updates

Ethernet firmware upgrades are supported by the Monitor/Loader of the following Tibbo devices: EM500, EM510, EM2000, EM2001, TPP2(G2), and TPP3(G2). This means that not every Tibbo device with an Ethernet port supports Ethernet firmware upgrades from the M/L.


To perform an Ethernet upgrade:

  • You must have the firmware file you will be sending into your device. There are two possibilities:

  • You must connect your Tibbo device to the same Ethernet LAN segment with your PC:

    • EM2001, TPP2(G2), and TPP3(G2) devices have the RJ45 Ethernet jack.

    • EM500, EM510, and EM2000 require an Ethernet front-end (magnetics and RJ45) to be connected externally. If your EM500, EM510, or EM2000 module is "on its own" (not integrated into a host device), then the easiest way to connect it to the Ethernet LAN is by plugging it into an EV board. We offer EV boards for all three devices.

  • You will have to install our Device Explorer (DE) utility. You can install just the Explorer, or Tibbo IDE software (TIDE), which installs the Explorer along with it. Get the software here:

  • You will need to be able to push the MD button on your Tibbo device (or pull the MD line LOW).

  • Optional: you will benefit from observing the signals displayed by Status Green, Status Red, and Ethernet Link LEDs. EM2000, EM2001, TPP2(G2), and TPP3(G2) devices incorporate the status LEDs. The EM500 and EM510 do not have the status LEDs, but their EV board does.

Update procedure

After you have connected your Tibbo device to the Ethernet LAN:

  • Turn your device off if it was on. Press and hold the MD button (or pull the MD line LOW) and apply power to your device.

  • After the device powers up, release the MD button (MD line). The Green status LED will turn on — your Tibbo device is now in the update mode. In the beginning, the device will enter the Xmodem serial update mode, but will quickly time out. After that, the M/L will proceed into the Ethernet update mode. If your device is connected to the Ethernet LAN (as it should be), it will "link up" and the orange Ethernet Link LED will turn on*.

  • Run the Device Explorer. Your device should appear in the list and its version should read "TiOS-32 Loader." If you don't see your device in the list, click Refresh to rescan the network for Tibbo devices.

  • Select your device in the list, click Upload, and choose Load Firmware Through the Network.

  • You will be prompted to select the firmware file. Select the file, click Open, and the upload will start. The Green status LED will be on and flicker infrequently during the file upload.

  • Once the upload completes your device will reboot automatically.

* The arrangement is different on the EM500 and EM510. First, these devices do not have any LEDs. You will need to plug the EM500 or EM510 into the EV board to see the LEDs in action. Second, the EM500 and EM510 display the link status not on a separate LED, but through the brightness of the Green and Red Status LEDs: these LEDs will become brighter when the Ethernet link is established. For more information, see the EM500, EM510, and EM500EV documentation in the Programmable Hardware Manual (PHM).

Additional details

  • If the BLE update mode is supported by your device, the M/L will wait about 15 seconds for the Ethernet link to be established. If the link is still not on after 15 seconds, the M/L will proceed into the BLE update mode.

  • If the BLE update mode is not supported by your device, the M/L will be waiting for the link to be established indefinitely.

For more information on various update modes and how the M/L selects and handles them, see Update Mode Selection Flowchart.
