This is a post of mine from another site. Thanks for any help
I'm trying to upgrade from 1.0.30 to 1.0.73
Following this site http://www.vems.co.uk/forum/index.php?topic=120.0
I have the config.txt and tables.txt files
So I go on to the next step run download-config.bat When I run the program the command prompt says:
Overwriting saved config
ctrl-c to abort
-----------------------
press any key to continue
I closed it out after about 5 mins of just that
I'm sure there is something I missed
Also this is the first time I have tried connecting vems to the laptop It has vista ftl. I also can't connect the vems ecu to megatune It says "no response" when I click to test the connection
And vems is connecting through a usb adapter the laptop is grounded to the car I can connect through bray terminal using "man" or "manmll"
Thanks for any help,
Aj

If you're using Bray what gets returned when you send the character S (make sure that you've not sent Man or anything before that)
Using download-config.bat you should see the configuration stream down the screen.
Make sure that the com port is set correctly in the batch file:
Right click on download-config.bat and select Edit, you'll get to see this:
@echo off
echo OVERWRITING saved config
echo ctrl-c to abort
echo -------------------------
pause
if exist config\config.txt del config\config.txt
if exist config\tables.txt del config\tables.txt
tools\megaloader -c com4 -o config\config.txt
tools\megaloader -c com4 -a config\tables.txt
Change the number com4 to the number of the serial port that your USB module is using.
USB serial ports are a pain in the arse, and god knows what Vista is going to be like on top of that.
"S" command returns Vems genboard v3 1.0.30
My mistake I had the terminal program open While trying to use download-config.bat
But now When I use it I get
Config file: config/config.txt
no hello from avr
Tables file: config/tables.txt
no hello from avr
my config.txt and tables.txt files are both empty would this cause that to happen?
I'm not sure how that happened though
Did you reset the VEMS after sending the S?
The empty tables and config files are as a result of the file being opened and then closed because the data didnt download.
I'd really reconsider the upgrade through a Vista box and a USB serial port... You are likely to have misery and tears ahead of you.

My laptop died I have to use my dads Vista sucks :(
I got it to connect with download-config.bat
I just assume I have to refill out my config.txt,tables.txt for it to work correctly though?
Also I can connect to miniterm In Megatune But When I test the connection I still get no response from megatune.
I succesfully upgraded my firmware and am now connected to megatune.
Thanks for the help Rob ;)
You will find that you need to sort the h[2] table when going from anything before 1.0.7x because the output numbering changed.
There is a post on the forum about it.
