Firmware Updates
Whenever the on-board software must be upgraded or modified, the new firmware can
be downloaded to the internal flash memory via the serial port COM0.
If the push button labelled with "Boot" in the rear panel is pushed while the system
is powered up, a bootstrap-loader will be activated that waits for instructions from the
serial port. The new firmware can be sent to the ANZ14 from any standard PC with
serial interface. A loader program will be shipped together with the file containing the
image of the new firmware.
The contents of the program memory will not be modified until the loader program
has sent the command to erase the flash memory. So if the "Boot" key is pressed
unintentionally while the system is powered up, the firmware will not be changed
accidentially. After the next power-up the system will be ready to operate again.
Inquiring Software Revision
The revision of the loaded software can be red out by sending the three characters
"
SN!
" via COM0 to the clock that starts sending the following string:
SN:FFFFFFFFFFFFFFFF REV:03.10/01
