![]() ![]() WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. The firmware update process did not work and trying to select a file/folder using Bootloader mode on the tool gave me these errors:ġ1:05:12 AM go into MPLAB, MPLAB will now download and install the new firmware for you.A week ago, I had a similar issue when trying an RN2483 (on a Lorabee) from version 0.9.5 to 1.0.1 with Microchip firmware tools using an FTDI cable. It'll revert it to a state that should allow MPLAB IPE to use it.Ħ. let it update, then go to Tools-> revert to MPLABĥ. ![]() If not, browse to the installation folder and choose it, it should be the only hex file visible in the installation folder.Ĥ. If it opens in the installation folder and you see a HEX file, click it. Now click Tools->Update/Download firmware/operating system (I can't remember the exact words).ģ. Plug pickit3 in via usb, use Tools->Check communication to check that you're reading it. Get and install the pickit3 programmer (. There are several ways of updating it, and sometimes MPLAB can do this for you, but this was what I had to do:ġ. If you get *Connection Failed* when trying to connect to your pickit3 in MPLAB IPE, this means your pickit has the wrong firmware. Ok, this might've been mentioned in the pickit thread but I'm gonna post this here so I could save someone else a couple of minutes: ![]() Restarting the software and reconnecting the programmer to the module a few times seems to "work". Looks like I didn't post my findings in this thread.įYI: For those using MLAB IPE v5 software, can be painful when it doesn't seem to connect/see the module for no reason. So something fishy is going on with MPlab and OS X 10.12.6 in my experience I eventually got it working by trying from my ancient Mac Book Air which is still running OS X 10.10, I installed MPLab (just the IPE) and it worked first try. I tried multiple USB ports and nothing worked. I am running OS X 10.12.6 and neither MPLab 3.5 (which I'd used multiple times in the past, using OS X 10.10, to update my IME modules), nor the new 5.05 with both IPE and IDE installed would 'see' the pickit 3. I was always getting the 'Connection Failed' note when I tried to connect the PicKit3 to the Mac.Įventually solved it by loading the Full IDE Software (Thats the IDE AND the IPE parts of the software).įWIW, this did not work for me. Had problems with Mac PicKit3 and the latest MPLABX IPEv5.00. Cobramatic wrote:This might help folks using a MAC and trying to do the update with the latest MPLAB software: ![]()
