Update Cellular Module Firmware - Digi LR54 User Manual

System administration
To recover the LR54, you will need a TFTP server that has an IP address of 192.168.1.100. The LR54
will use an IP address of 192.168.1.1. Any configuration on the LR54 will not be modified as part of
the recovery process.
Firmware recovery process
1. Download the appropriate LR54 firmware image from
http://ftp1.digi.com/support/firmware/dal/LR54/Latest/.
2. Rename the recovery image to image.bin.
3. Copy the image.bin file into your TFTP server directory.
4. Connect the LR54 device to the TFTP server using the ETH2 interface.
Note To recover the LR54 device, you will need a TFTP server that has an IP address of
192.168.1.100. The LR54 will use an IP address of 192.168.1.1.
5. Hold in the reset button on the LR54 and power on the device. The LEDs will begin flashing
green.
6. After approximately five seconds, the LEDs will stop flashing. Release the reset button.
The following will now occur:
a. The device downloads the firmware image from the TFTP server. Once the firmware image
is downloaded, the WWAN2 Signal/SIM 1 LED briefly lights.
b. The device verifies the firmware image.
c. The device reboots, loading and running the new firmware image.
7. After the device is finished rebooting, update the device to the latest firmware. The recovery
process does not write the recovery firmware to flash memory, so you must update the
firmware by using the normal firmware update so that the new firmware will be persistent
across reboots. See
