5.4.5Firmware update

Occasionally there may be updates to Mint to either fix problems or to add new features.

The Mint firmware is stored in Flash memory and can be updated using the RS232 serial port. The RS485 port cannot be used for firmware update.

CAUTION: The state of the analog and digital outputs cannot be guaranteed while firmware is being updated. Please disconnect any equipment which may be damaged.

CAUTION: It is recommended to remove any AUTO configuration file prior to updating firmware. Changing the firmware may affect the way your Mint application works.

CAUTION: Updating firmware may destroy any program(s) held in the battery backed-up RAM buffers. You should upload these into Mint WorkBench and save them before updating the firmware.

CAUTION: Updating firmware will destroy any program(s) held in the Flash memory buffers. You should upload these into Mint WorkBench and save them before updating the firmware.

From the Tools menu, select Update Firmware and follow the instructions on screen.

Once the firmware has been updated, both the Configuration and Program flash buffers will need to be reset. The Mint keyword BUFFERSTORE can be used to switch between battery backed-up RAM and flash buffers. Typing:

BUFFERSTORE=0 will switch to the battery-backed RAM buffer. Typing:

BUFFERSTORE=1 will switch to the flash buffer.

With the flash buffer selected, type:

CON to select the configuration buffer (if it is not already selected).

A few report lines will be shown, followed by the C> prompt. Type:

NEW	at the prompt to reset the buffer.
Now type:
PROG	to select the program buffer.

A few report lines will be shown, followed by the P> prompt. Type:

NEW at the prompt to reset the buffer.

It is recommended to update the keyword tables supported by the controller after updating it with new firmware. This allows the Mint WorkBench editor to identify keywords recognized by the controller. To update the keyword tables, select Load Syntax from the Edit menu in Mint WorkBench.
