Interested in BSP's (No idea where to start?)

[Niteesh]

Hii, everyone
I am interested in contributing to RTEMS, specifically to the arm based
BSP's. I am a sophomore in electronics and communication engineering
interested in operating systems, and systems programming. I have written
small drivers and libraries for Arduino, bare metal avr chips to interface
with sensors. I would like to take it a bit further by learning about
ARM-based devices.

I have completed the hello world task for GSOC. As I said early I am
interested in contributing to the drivers and BSP section for most likely
raspberry pi and beaglebone. But I have no idea how to proceed further, any
suggestions on where to start and is it okay to ask tons of questions?
because I had a look at the previous year's project ideas and very little
made sense to me. I am ready to put in my best effort just need some
guidance from your side.
