Can anyone help me find the oficial firmware for the chip kit wf32 board? i have can't find it in digilent's website.

I haven't looked too deep, but it uses the same chip as the MAX32. It probably uses the same bootloader too.

Thank you for your time, but i think they use different MCU. The MAX32 uses a PIC32MX795F512 and WF32 uses a PIC32MX695F512L.

The only difference between them (IIRC) is the lack of a CAN module in the 695. Other than that they are interchangeable.

Do you think is safe using MAX32's firmware? I do not want to void an warranty, i have just bought this board and i am getting an "avrdude: verification error; content mismatch" error. Do you this will solve the problem, or is this risky to void warranty and end up with a faulty board?

Well, it won't physically break it, but if it doesn't work your board won't work until you put the right bootloader on. Either way the bootloader is software, and I don't believe the warranty would have anything to do with it.

If you have MPLAB-X and XC32 (both freely downloadable) you can download the source code for the chipKIT bootloaders and create your own from [url]https://github.com/EmbeddedMan/PIC32-avrdude-bootloader[/url] - it would just be a case of copying the configuration for an existing one and making any necessary changes (if any are in fact needed).

I will try it. Thank you for your time and happy holidays. Have a nice day.

Digilent has now posted the WF32 bootloader.
