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?
