BootingtheA753
This section is included for informational purposes. You will rarely
need to boot the A753. However, when you do need to do so, you will
work within a Windows Hyperterminal window or similar terminal
program on your computer.
BootloaderMode
When the A753 starts from a power-up reset (such as when you
connect the battery to the unit), it enters the bootloader mode. If you
press no keys in the interim, the A753 enters the firmware mode in
five seconds.
If you want to work with commands in the bootloader rather than
continuing to the firmware mode, press the ESC button within five
seconds after seeing the following sign-on message:
A753 with Bootloader V2.1, Firmware V2.1, Coprocessor
V2.1

Press <ESC> within 5 seconds to start the commandline
interface...
You are in the command line interface of the bootloader. This interface
enables you to perform certain commands such as upgrading to a new
firmware.
Note: If you press no keys within 60 seconds, the bootloader command line
interface will start firmware mode automatically.
The bootloaders’s prompt is the character >. Therefore, when you see
this prompt, you’ll know you are in the bootloader mode.
