Open a command prompt, and “change directory” to the folder you extracted the files
to, and run the following command on your PC (for example): -
vig_avrsp.exe –pv1 -d20 SF0446_V1.05.mot
–pv1 is the PC comms port number. Set it to some other number if you use a port
other than COM1. –d20 is a delay parameter. Try increasing the number if you have
a very fast PC and get an error. SF0446_V1.05.mot is the new firmware file to
download.
Check that the PC displays (this process takes up to ~1 minute).
Detected device is ATmega164P.
Flash: Erasing...Writing...Verifying...Passed
Then run a terminal emulator on the PC, as described in section 4.10. After you
have started the terminal emulator, remove LK1 or place it on one pin only, and the
VIF should restart with the new firmware. The position of LK2 does not matter now.
Check that the version displayed on power up matches the new version you just
programmed.
Note: this procedure works best with a real serial port. With a USB to serial port
emulator/convertor it should work eventually, but will take many minutes.
Table 4-11 – VIF Firmware Versions
1.01 –
Earlier versions. These are not compatible with QE20. Either the firmware
must be updated to at least V1.06, or the VIF replaced with a newer one.
1.04 Added delay before sending reply on QEComms. Revised some timeout
values for use with ATA 192.
Removed delay for use on QE90.
Changed delay so removed click on audio. Required for use with QE20.
