The board isn't visible in the device manager.
The power is ok. All leds are ok.
Perhaps there is still a fault in the board or is this only a software problem ?

If the processor is correctly installed and getting 3.3V power, then it should show up as Bossa Port in Device Manager. You might possibly need to press the Erase and then the Reset button The bootloader is in the ROM of the processor.

The processor was indeed correctly installed and the power was ok.
The problem was the USB cable. There where no datawire connection in the cable , only power connection.
I think that this cable was an old power cable from a cellphone ?

So now we can start again.

Thanks for the help.

Regards

Yes, I've been caught by power-only cables before!

I have a 0.6 with the same problem. It would be great to have a spare. Where did you get the processor from? Was it difficult to replace?
