AVIDdirector-M2M™ Technical Reference Guide

Appendix 7 – Upgrading the M2M Java Firmware

Locate the CD included in the SDK, and then locate the directory “SNAPDev_Files” which contains the files

needed to reload the device. You may also download the files from the AVIDdirector web site where you will find

the latest firmware update. The zip file contains three files with a .snp extension.

You will need to remove the cover of the AVIDdirector-M2M device before attaching the debug pod. Note Remove

the antenna before removing the cover. Be sure to match pin 1 on both devices before powering up the device.

The black line on the ribbon cable should match to pin one on both boards. Attach the Developer pod to your PC for

reprogramming with a standard serial cable. Attach the serial cable to your computer COM Port (you can use a

USB to RS-232 adapter). Verify that the COM Port the serial cable is attached to has a baud rate of 57600.

Execute the SnapDev.exe file located under the SNAP/bin directory to start the Snap Development environment.

Then connect with the File | Open Port

Power up the AVIDdirector-M2M device and boot up. As the device

starts up press the "i" key a couple of times as the startup messages

begin to be displayed to prevent the M2MApp software from starting

(this bypasses execution of the /system/startup.ini file)

To determine what version of the firmware your

device is currently running, once connected enter

the “info” command.

From SnapDev choose File | Reset F5 or press F5

to enter loader mode. You should see a progress

bar on the bottom status line of SnapDev as it

downloads the initial boot loader. When that is done you should see a prompt like:

SNAP loader v 0.1.10 (Build date: Oct 17 2004 01:03:31)

Note: If you do the File | Reset and you don't see the status line start a process bar on the

bottom, press the reset button on the board just after starting File | Reset.

The AVIDdirector-M2M board has a reset button on the top of the main board. This button can

be used for a hard reset of the device while debugging.
