Thanks for the reply Christian. If I'm writing to a local memory location why would the change in value not show in the debugger, even if that location is memory mapped to a hardware register?

From my experience this heavily depends on the device behind the

"memory location" as this is not RAM. The device may, for example, interpret bit 0 set on write as "clear register", which would gain you 0x0 on writing 0x1. Note, it was just a plain guess as I do not know your platform or device very well.

BTW, which Ksyslabs repository and branch did you base your work on? Does it already include a GPIO driver for your BeagleBone?
