FPGA bitfile name change

[stuwatt193]

I have been compiling FPGA code in Labview 2013 for the NI myRIO and can successfully get a working code. however when i try to use it on another computer the .lvbitx file name changes from the one that is in the build specification. i have tried selecting the newly named file through the build specification but when check the signature it says "the bitfile does not match".

is there some reason for this?

Hi stuwatt,

That is strange behaviour. What happens if you rename the bitfile to match the build specification?

Hi stuwatt,

As a follow up question, do you actually call the FPGA bitfile from a real-time VI on the RIO or is this a stand alone FPGA bitfile?

Thanks for your reply.

I tried changing the build spec but it didnt work.

I am calling the bitfile from a real-time  VI on the myRIO. i have the reference set up to use the bitfile rather than refering through an FPGA VI.

Hi stuwatt,

What happens if you actually change the name of the bitfile, rather than the build spec itself?

The following link might be of interest to you w.r.t. the name change:

I've followed that advice hundreds of times with cRIO and sbRIO code without seeing any signature errors.

Thanks for the replies. I took a look into all the suggestions but i can only get one of 2 FPGA codes to work. i have attached the code in a zip folder if anyone is willing to have a look and give some insight i would be very greatful. 

i can get "FPGA Blip Generator" to match by changing the bitfile name in the build spec or vice versa however "FPGA - 4 - Final w sub" still wont match.
