Thanks for your advice, Tom . Problem solved.


I used the1.2.7  hex file from your homepage. I built a new project and I
was able to flash the OVMS. 


The Tesla homelink function from iOS App works very well . Better than the
homelink in the car (sometimes I have to touch  the screen 3 to 4 times).


The other functions (especially speedo) are working good.

I'm using:


Product Version: MPLAB X IDE Beta7.02 

Java: 1.6.0_31; Java HotSpot(TM) 64-Bit Server VM 20.6-b01-415 

System: Mac OS X version 10.7.4 running on x86_64; MacRoman; en_US (mplab)


mcc18: v3.40


My mplink, on a clean-and-build gives:


/Applications/microchip/mplabc18/v3.40/bin/mplink    -p18f2680  -w

MPLINK 4.40, Linker

Device Database Version 1.3

Copyright (c) 1998-2011 Microchip Technology Inc.

Errors    : 0


I'm on a mac, running the beta mplabx (if it ain't broke, don't ...)


Are Tom and Piotr getting exactly the same error in the hmac module? Strange
because that module hasn't changed since the beginning of OVMS.

I had the same problem trying to build last week. Mark gave me a list of
things to check, then life happened and I just got back to it.

I'm using MPLAB X v1.10 and mcc18 v3.40.

I chose TR_Production for the build settings, confirmed that mcc18
optimizations are set to "Enable all" and did a "Clean and Build" (not
"Clean and Build for Debugging").

I still get the linker error, same as before.

I get the same result for the TR_Experimental build.

Wondering if I had done something to mess up my sources, I deleted the
entire OVMS project directory, did a fresh git clone, and repeated the
steps. Same result.


PS: You can copy from the build output window and paste into a text file.
This yields a much smaller email attachment and it doesn't crop off the end
of the build commands.

Hi guys


Unfortunately  I have a problem with the compilation of the firmaware files

1.2.7. I'm using MPLAB X DIE 1.00


Please see enclosed picture.


I can't compile the project and also the use of the hex-file for flashing is



Does this sound familiar to anyone?


The previously released firmware versions worked out fine.


Greetings, Piotr
