Firmware update warnings — read before updating either card:

• Do not disconnect the card at any point during the update process. Doing so may cause irrevocable errors and may permanently damage the device.
• Attempting to update firmware while running virtual machines will result in firmware upgrade failure.
• The compressed firmware file contains two files, a .bit and an .img. Perform the update step with both files.
• For updates to persist after power cycling, allow 5 seconds before disconnecting or restarting the device.
• On macOS the "Update Completed" text does not appear. Completion is indicated by the progress bar filling and the window no longer being greyed out.
