1) Retry the firmware update manually
Updating the firmware on your APDM hardware requires that the hardware is first placed into what is called the bootloader mode. If the firmware update is not started or does not complete correctly, your Opal may appear to be stuck in this mode. If you encounter this situation, follow these steps:
- Dock the hardware and wait for 10-15s and make sure it has been detected on your computer. This will be true if the green LED on the docking station next to any Opals are illuminated, and that the green LED on the back left of the docking station is illuminated if you have an access point plugged in there. If this isn't true, make sure that the docking station is connected to your computer and that the green light on the front right of the docking station is illuminated.
- Within your APDM software (Motion Studio, Mobility Lab, etc.), click on Tools->"Update Firmware"
- Click on the "Flash Default Firmware" option
This process should find the hardware that is stuck in the bootloader mode and complete the firmware update process.
If this does not work, the following steps should be tried:
2) Make sure the bootloader drivers are installed (Windows only)
During installation of your software on the Windows operating system, there are 5 sets of drivers that are installed. These cover both our v1 and v2 hardware, in addition to a driver that enables Windows to talk to v2 hardware when it is in bootloader mode. It is possible that not all drivers were installed at during this process (e.g., if one or more steps were skipped). Alternately, sometimes Windows does not load the correct driver unless the hardware is attached to your computer when the driver is installed. To re-install the drivers:
- Make sure that any devices in bootloader mode are connected to your computer and detected by your computer, as described in step 1)
- Locate your installation directory. This is typically "c:\Program Files\MobilityLab"
- Double click on the file named "dpinst.bat" and follow the steps to install the 5 drivers
- Attempt the firmware update again
Note: On MacOS, no driver installation is necessary
3) Make sure the devices are being detected correctly (Windows only)
If the above steps still do not work, it should be confirmed that Windows is loading the correct driver for your devices that are in the bootloader mode.
- Go to the start menu and type "Device Manager" in the search bar
- Confirm that there is a top level entry with the name "APDM, Inc."
- Confirm that the APDM devices you have attached to the computer and are in bootloader mode are listed under this category as "APDM V2 DFU Bootloader". This may be easiest if you remove any APDM hardware that is not in the bootloader mode.
4) Reset the devices and try the firmware update again
If the steps above do not correct the issue, it is recommended that you bring the devices out of bootloader mode and try the firmware update again. The access point will reset when unplugged from the computer, but any Opals will have to be reset. To perform the reset operation: a) Plug the Opal directly into a powered USB cable (either connected to your computer or a wall charger, not the dock as you won't be able to access the buttons), b) Hold both buttons for 30s until you see the LED come on. c) Let go of the buttons to reset the Opal.
Then, try the firmware update again, as per step 1) at the top of this article.
