Deutschmann Automation GmbH & Co. KG Firmware-update
11 Firmware-update
11.1 Overview
UNIGATE
®
IC has a 64 kbyte flash memory for the firmware. In the firmware-update-mode the
firmware can be replaced via the UNIGATE
®
IC’s serial interface.
11.2 Adjusting the firmware-update-mode
11.2.1 Adjustment by hardware
UNIGATE
®
IC can be brought to the firmware-update-mode by the hardware. For it the signal -
BE (boot enable) has to be pulled to the potential GND during the Power-up-process.
11.2.2 Adjustment by software
If the UNIGATE
®
IC is in the configuration mode (see chapter 7.2 on page 27) it can be brought
to the firmware-update-mode interactively through the command CTRL-F (0x06). After sending
the command a security query follows, that has to be answered with J or N (J = Yes, N = No).
After a positive confirmation the IC is re-started in the firmware-update-mode.
11.3 Execution of the firmware-update
The safest way for the firmware-update is the use of the basis board combined with the software
“FDT.EXE“ (firmware-download-tool). These tools are available from Deutschmann Automation
(see chapter 13 on page 42).
11.4 Note on safety
The firmware-update should only be carried out when there is no other possibility left. A firm-
ware-update-process that has already been started CANNOT be undone. With it the previously
used firmware is permanently unusable.
11.5 Operation mode of the IC
Standard-operation mode
This mode is required for the regular use of the IC. In this mode the IC will process all script-com-
mands and normally exchange the corresponding user data. The bus as well is operated in this
mode through the IC.
Configuration mode
In the configuration mode the UNIGATE
®
IC will carry out a self-test after the start (or after a
reset). After a successful self-test it will wait for further commands. Here it is possible to load a
trnslated script into the device or to initialize the firmware-download-mode.
