Upgrading Firmware
STEP 1
Connect RWC1020A to user PC with USB and confirm COM port is
installed correctly in user’s PC
STEP 2
Download the avrdude from the website.
https://sourceforge.net/projects/avrdudegui/
STEP 3
Download psg_upgrade.bat and rwc1020a hex files from the
Redwoodcomm website and copy them into the avrdude tool
directory.
STEP4
Run psg_upgrade.bat file or run command as follows COMn should
be modified same to the COM port number that is installed in your
PC. ( avrdude -p ATXMEGA256A3 -c avr911 -P COMn -b 115200 -e -V
-U flash:w:"psg_ctrl.hex" )
All responsibilities of upgrading firmware lies with users
