a) hopefully you not only connected tx and rx but gnd also.
b) maybe there is a problem with the procedure:
1) connect usb-serial converter
2) set jumper
3) reset or alternatively power on board
4) start flashing
5) remove jumper
6) reset or power off/on board
this should get you going.
depending on the us-serial converter it might be necessary to
a) remove rx/tx before 6)
b) cross over rx/tx

I'll try asap hoping you advice were useful
Thank you!

These boards are known for having misleading labels.
Instead of connection RX of board to TX of convertor (and vice versa) you have to connect RX to RX and TX to TX.

Really?
That sound adsurb! Anyway, I'll give a try!
Thank you

Yeah! That's it!
Thank you so much, I hope this info will be useful for everyone who own this dev board!
