Hello Poine,

So far we have mounted:
-MCU and all components supporting it
-3.3V regulator and associated components
-USB connector and associated components

To be mounted for LED test program (as we understand)
-Bootloader molex connector
-Remaining LEDs associated 1K resistors

1) Shall we follow the same instructions given for Tiny bootloader flashing? That was our expectation considering the hardware is the same with regards to the bootloader connections.
2) Also We have Ubuntu running on a virtual machine. Could this pose any problems?

We would like to have the bootloader flashed very shortly. I am preparing for both bootloader flashing and LED test program upload and execution.
We would like to test the LED hello world program before populating the other components so that we can verify functionality of the the MCU first.

You don't need PPS. It's a timing signal generated by the GPS, which
we're not using at the moment.
About test programs, take a look at the wiki  ( ) , there's already a couple of
things there, which I intend to extend ASAP. Did you flash the
bootloader ?
