Can I still work with my RPI B3 + or should I buy a RPI2?
The RT download problem comes from there?

Hello everyone.

I apologize in advance for my english but being french! I use google translation ...: - /

Here, I have an old pc that is still running under vista and I am using it to program my uniPi card.
The problem is that when I do a search with "attach PLC" in "UDP broadcast" mode, this one only finds a uniPi / RPI 2 rev 1
while I have a RPI 3B +.

I specify that I connect the pc and the UniPi / RPI ethernet cable right because being on my boat (I am a sailor) I can not access network configurations.
I tried to manually enter the model and the serial number, it seems to go except that I can not upload RunTime. it puts me: "upload of RT fail".
I also tried leaving the PLC found by itself (RPI2 rev1) but I have the same problem with the RT upload.

It's been 3 days that I block above and I go around forums but impossible to find a solution.

I installed Mervis IDE V 2.0.12 (58620).
I tried to put on my SD card all OS images available on the site but that does not change anything.

thank you in advance.
