4.4.18 F100 BUB - Burn BootLoader
Use Burn BootLoader when upgrading software, to write the BootLoader to flash memory.
To write the BootLoader to the flash, send the F100 BH command with the FTP
host, file path and name, and then send the following command:
F100 BUB<Enter>
The unit responds:
Are you sure? (y/N)
If you answer “y” and press Enter, the unit executes the command.
As a safety feature, after sending this command, you have 10 seconds to respond
affirmatively (enter the letter “y”) to the confirmation prompt, after which the unit
executes the command and resets. Within that 10 second time period, any other response,
including no response, results in the unit canceling the command.
