GBOARD...I have a arduino compatible gboard micro controller with SIM900... I strugle a lot with this microcontroller, there is very little info about it on the internet. Could somebody please explain to me how to run my arduino code on it. I have the FOCA board for usb comunication between computer and the microcontroller.

Can you be more specific with your question? What errors are you seeing? Having never heard of gboard until now, I googled 'gboard arduino' and found heaps of references including a wiki page. With the FOCA board for FTDI it appears you have everything you need to get cracking.
