NefMoto

Ok so I got cable with FT232R chip in it so I could try and use NefMoto. I could get the software to work using a bench harness with OBD mode but not boot mode so I was looking through the forums to see what worked for others and seen some where having luck using a resistor of 1k ohm
inline with the boot wire so this is where the problem starts ... I grabbed the wrong resister it was supposed to be 1K ohm and some how I mixed it up and put in a 10k ohm so now my ecu is not  communicating at all do any of you guys have any clue as to where I should start looking for the fried component on this ecu..

Thanks Mark

There is almost no way you killed it when shorting to GROUND with the wrong resistor

If you down completely and power it up again and it should respond via obd again.

Nefmoto is not capable to operate in boot mode.

If you would experiment with bootmode you should use argdubs eeprom tool at first and later try to modify galletto to work with your cable to access the flash in bootmode.

Shored the wrong pin and fried the proc

I did not know that Nefmoto wouldn't work in boot mode so  there wasn't even an issue there thanks... and yes I already use argdubs eeprom tool and me_7exe

Thanks mark

I've had a wire soldered to the boot pin for two weeks now so I dont think that's the case but now I'm second guessing if I reversed the leads in power supply

Thanks mark

If you reverse the leads without the boot pin connected nothing will happen.
If you reverse the leads WITH the boot pin connected, then even with the 10k resistor you most likely fried the address line on the micro as that saw 12V.

I really don't believe that I reversed the leads because the same leads power the cable and that's fine but the ecu is dead even in the car I get no communication with cable and the car wont start...  so is there anything I can check with a multimeter

Thanks Mark..

What pin did you ground out?

Pin 24 I have a wire soldered to the grounding point for boot mode which is here

and it hasn't changed Ill i did was put a resistor on the end of the wire .... So I Thought ..... ??? ??? ??? Blows my mind lol

Thanks for your help

Which one of those pins did you do that to... the left or right. it makes a difference.

Also, what did you ground it to? to the ECU PCB I hope?
If you grounded it to the power supply, and at any point the ECU had +12V but no ground then that will instantly fry the processor.

There's nothing you can check, buy a new ECU.

The 1 on the right that's the 1 ktag shows don't know why there's 2 circled

I would hold it to the gold border around board

More inclined to think your set up is not working correctly.  Did you try rebooting your pc and check device manager for correct port? And check settings?  Check your connections again ?  Do you have a digital power supply is there any current being drawn when you power up? Check Kline wires?  If you put your obd reader back in the car I’m sure you can check address 2 tranny or some other module.

I did not check com port ..  I will follow all suggestions this evening and follow up...

Ok checked the com port that was correct.. The cable is recognized in vcds and nefmoto when I power on the ecu the ecu and cable are pulling 0.245 amps so im thinking dead.. and the more I think there's no way I reversed the power because its all soldered and it worked over a dozen times...

Here is the log file

Did you try going through all the different baudrates?

I'm pretty sure it's done I have a chip on the right side of the board heating up pretty good...
