Default Expected response "boot", but got ""

Hey guys...hate to come on here just to ask a megasquirt question, but I'm really trying to get this thing running really quickly and I know the supreme Gods of MiataTurbo.net are probably the only ones who can help me.

I am trying to flash my MS1 with Extra 029y4 and keep getting the infamous "expected response "boot" but got "" " error message even with the car in "run" and a boot jumper in place.

I have tried 2 different laptops and still no dice.
The 2 side lights light up and stay lit, the center light hasn't flashed once.

Any ideas would be appreciated.

lights shouldn't come on with the boot jumper in place IIRC.

wellllllllllll then.
I was just using 16 gauge wire as a jumper...is that what I'm supposed to use, or is there more to it?

Sounds like the boot jumper is not properly installed. If the wire isn't making a solid contact, then it's no different than if it were not installed at all. Try using a paperclip, and bend it so it makes a solid connection to both pins.

Well if that's all there is to it, I'm gonna feel like an idiot. Now I am going to walk to lab in the rain though, and I will try that after I walk back. = [

The unit was built by a friend, who loaded the firmware and my old .msq and tested it on a stim...is there any reason that stuff would get messed up during shipping?

Not likely. What happens when you run portcheck?

Portcheck finds a valid port on both my laptop and the netbook I borrowed.
COM3 on the laptop, COM4 on the netbook. I am using the appropriate ones when I run download-firmware.bat and download-firmware x64.bat in the case of my laptop, and still nothing.

It has been a while, but I believe I had the same error with a certian USB-serial cable. it would work fine for normal connectivity, but i couldn't burn with it for some reason. Bought another cable off of newegg and had no issues since

This exact cable and adapter has been used to burn and to flash firmware before.
It is also DIYautotunes serial adapter, so I'd assume it's solid.

I now have no lights on after messing around with the boot jumper, but still get the same error when I run dowload-firmware... = [, I was so happy when the lights went out.

EDIT: Actually now the lights won't even turn on without the boot jumper.
I am thinking about returning to my old parallel setup, but I really didn't want to do that...was trying to clean up wiring and get some PNP action for when I need to smog.

If anyone happens to be around Irvine, CA with another computer/serial adapter...holler.
Really trying to get this thing going today, thought it'd be easy like always, guess not.

I had the same issue. Did you remove that fuse, for the StarterST or whatever it was. I talked to the guy at DIYAutotune, and he said I must have jacked up some resistors in the MSPNP and i'd have to mail it back to him to fix, that was almost a year ago (i'm deployed so not much i can do about it).

The ST SIGN fuse only applies to MSPNPs, and the consequences of forgetting this are a blown output transistor but no further damage.

well, the issue never really got resolved.
Took the processor out of the board made to run standalone w/ a DIYBOB, and put it into my old parallel-install board, and it flashed first try, on my 64-bit computer, without a bootjumper.
So I dunno. Something screwy with the board or harness/BOB.
