MerloZ Posted December 24, 2016 Share Posted December 24, 2016 Hello i am new to this forum so i am not sure im doing this right but. i recently bought a ms2 DIY kit from diyautotune and all was going well until i was instructed to download the firmware. I got the firmware and downloader from msextra, i run the program and i get a message (in picture). i have checked my power multiple times and the megasquirt has passed all the previous tests using the db9 adaptor from diyautune and the stimulator. i have researched everything and can not find any information on how to get the firmware downloaded with this problem. Ive been struggling with this for a total of 7 hours by now and i just want it to work. ive tried everything. HELP ME!!!!! lol. Quote Link to comment Share on other sites More sharing options...
ZHoob2004 Posted December 24, 2016 Share Posted December 24, 2016 Do you need drivers for the usb serial adapter? Check your device manager (win 8+ right click start button -> device manager. Previous versions just use the start menu search). It looks like the firmware script couldn't find a com port and I'm guessing it's not got a driver for it. Disclosure: I don't have a megasquirt but I've used a lot of usb serial adapters. Quote Link to comment Share on other sites More sharing options...
schicksal Posted December 24, 2016 Share Posted December 24, 2016 Did you put a jumper on the ms2 board on the b/ld pins? Quote Link to comment Share on other sites More sharing options...
