MicroSquirt.com read only forum (Jan.15,2018)

Been a couple weeks since I had time to work on my bike hooked up lapyop to it and no communication. Nothing has changed Its done this before but I would reload the code and it would be fine. now when i try to load the code
i get:
ERROR: Timed out reading response, 0xE0
Elapsed time: 15.20 seconds
ERROR: Unknown error status response, e=0x5F
Elapsed time: 0.05 seconds
I've reinstalled megatune and have the latest code ant ideas?

I forgot to mention i am using a USB to Serial adapter.

OK from what I have been reading I dont have the correct ini file that's what causing the error message.Would someone please confirm this and if true how do I get back to the correct ini file.

195s,

The incorrect INI file will usually give a warning dialog in MegaTune that says the "received" code signature does not match the expect "expected" signature. INIs are used with to download code in any way, anyhow. However, the code and INIs are here: http://www.megamanual.com/ms2/code.htm and also see: http://www.megamanual.com/ms2/downl2.htm Make sure the bootloader wire is grounded when powering up before trying to load code (this is the equivalent of putting the bootloader jumper on MS-II).

To me, this sounds like it might a problem with communications, so you might want to check: http://www.megamanual.com/connect.htm

Thanks Lance i will give all that a try tonight. Do you think it would better to use a PCMCIA to serial vs a USB to serial adapter.

Well I found a bad ground And fixed it the bike runs but still no comm. I now get this when I try to load the code.
ERROR: Timed out reading response, 0xE0

thats different than before when i test the port in MT it says no response

I'd try checking the serial cable for continuity at this point.

Thanks Matt
I tried that the other night the cable is ok but I dont know how to check the usb to serial adapter.
I'm going to order a pcmcia to serial card.

Well after weeks of pulling my hair out trying establish communications with my Microsquirt I finally contacted the guys at DIY Autotune where I purchased the unit from.
Justin was very paitent with me and tried to walk me thru some trouble shooting but still nothing. So on his advice I boxed it up and sent it back to them. After just 2 days Justin wrote me back
saying the comm chip was bad and they had never seen that before (just my luck). They upgraded my board to a v2.0 and shipped it back to me free of charge. I cant say anough about their service and how they handled
my situation. Thanks DIY Autotune.

Hi
I am posting here because I have a V2 board, and had no issues re comms todate. The other day whilst do cranking tests, and switching between TachRef and "a run code.s19", using MS Download 2.00 I got this error.

Reading C:/Documents and Settings/Mike Crane/Desktop/Monitor_v2.888a.abs.s19:

I don't seem to be able to communicate with the MicroSquirt. I have about 13.2V on the battery, 5.13V on the VRef and I have always had the bootload wire tied to 5V, or ground when loading code.
I am using the same USBSerial adaptor, and the LED faintly flickers, but will not flash/illuminate like before
Is there any checks I can do? Nothing smells funny, I have checked the polyfuses and they are OK. I have visually looked over the pcb with a magnifying glass, and nothing looks untoward. I have even used an infrared thermometer and the only area that is slightly warmer is the area around the voltage regulator L53B & another marked S27BA, but it is only 7 dec C above ambient.

Any suggestions please?

PS Another error message.
