The re-entrant coder

Well, got a nice perk this week at work: assisting in getting an embedded linux board up and running. To be honest: it is a nice little piece of work, called a FriendlyArm. It is an ARM9-based development board, costing less than $150 with an 3.5″ TFT with touchscreen (optional 7″ touchscreen). It is fitted with 64Mb RAM and 64Mb Flash, and 2Mb NOR.

I’ll be trying to get this to work, so expect updates on the blog. Eventually, I’d like to get Android running on this board as well (but memory may be a problem).
