I just bought a beagleboard xm Rev C and I configured using narcissus(angstrom) and the linux is running perfect.
Now that I have an application which is kind of an acquisition system which requires a good GUI, which communicates on RS485 interface and ethernet.
As I am new to embedded linux and beagleboard xm Im kinda confused on where to start. I right now have a XDS100v2 emulator with me.
What I thought is, first I will write the drivers for rs485 and add it in kernel(hope the procedure is adding support in /dev),now if i add it this way where can I test my rs485 communication? Can I use qt for testing or debugging(with XDS100v2)? or CCSv4(which is offered as a free license with XDS100v2)?
Can you also suggest me a good environment for starters like me or some blogs or tutorials to start?
