Motor Controller wont update

I had a similar problem (see my post on "My Vectrix is now a doorstop (failed firmware update attempt)").
Once the MC firmware is in this state (no flash-resident boot loader) it is no longer possible to load firmware over the CAN bus using the scooterdiag software.
The only way to re-load the firmware at this point is by using the JTAG programming port. I am planning to attempt this, but to do so I need:

a) a JTAG programmer
b) the MC firmware from Vectrix in .out format (.hex format does not work for JTAG programming)

I am still waiting on Vectrix service support to respond to my request for the MC firmware in .out format.
Keep and eye on my "doorstop" post for updates on my progress.

Regards,
Scott

Scott - keep badgering Vectrix won't you? This is something that would be sooooooooo useful to a number of vectrix owners. I think I have access to a JTAG programmer at work - and you'll be the first person I've heard of to successfully re-flash the firmware if you can get the right .out files. If you do get the file, I'd love a copy.

Best wishes - here's to non-doorstep status!

Scott, I've just had another quick look this morning and it might be possible here http://emulators.spectrumdigital.com/utilities/sdxmlgui/Readme_dsk6000_v1.1.pdf
If you look at section 4.2.1 it says the following....

Converting .hex to .out file: The utility AsciiHexLib.exe is used to convert .hex
to .out. This utility is located in our main working directory (See Section 9). Put
post.hex into your main working directory. Point the command window to that
directory and type in
AsciiHexlib -hex post.hex -out posttarget.out
Now point your flash program data file to this directory from the SDXMLGUI
application. This bootable .out file can be programmed into Flash so that the board will
boot it and run POST example in standalone mode when it is powered up independently
of the debug environment.

I blew a IBTs (PM300CLA060)and thought I might try to replace it with a new one at $400.
After instalation, I jacked up the wheel and switched on the bike, calibrated encoder, then it seemed to accelerate when I turned the throttle.
but no reverse, it was a bit chuncky so proceeded to reload MC firmwware.

If the wheel turns but is choppy, it usually means a lost phase

If the IGBT connections are good, the next place to look would be the opto-couplers between the gate drivers and the processor

given the original IBTs failed, there may be other SMD parts on the logic side that may have failed aswell

Matt

oops, for a moment there I thought the TI microprocessor was what had failed and was replaced

given there is a new IGBT installed, a failed opto is still the next step

another possibility is one of the 4 x 15v powersupplies for the IGBT have failed

until the Jtag process works, replacing the microprocessor may be necessary

Matt

Encoder didnt move the wheel, just the speedo needle to 100 four times
Bad news is even thou I have the GO sign, no motor movement, still dead,

The wheel barely moves during the encoder calibration process

You do have to turn the power off and on again for the calibration to save, it doesn't work straight away.

I would also see if the MC will pass the motor rotate test:

hold accelerator to full while holding the left brake on, and turn the bike on

The wheel should rotate slowly

If it does that, it would suggest an issue with the encoder

It's like accelerator isnt connected, looks like Its comming out again.

when you have the kill switch on with left brake held
what does the speedo show?
does it change when you change throttle position?

If so, the throttle is working fine
If not, there's your problem

Are you able to test/diagnose/repair the Board yourself if, I send it over Matt?

I can put it in a friends spare Vectrix and see what it does

He's much more skilled and better equipped than I at MC board repair, together we could probably get to the bottom of it

Try the easy tests first before sending it off to me
It may be a few weeks before we can work on your board, but may have another good one ready to ship before then

Matt

I see you are asking for a new/replacement board.
How far did you get with the repair of the old one

Has matt looked at it ?

PM me if necessary.

Cheers

Chris
