Re: Writing Pin-muxing registers in an am3359.

I write a value of 5 to the register offset 0x800 into the Control dataspace: /[init -> gpio_drv] mmio write 0x4800: 0x00000005// //[init -> gpio_drv] void Omap_driver::set_pin_controls(int, int, int): B=1, P=0, Mode=5, Input=0, Offset=0/

In jdb I see that the value at 0x4800 has not changed after apparently writing 5 to it.

It's just a guess, but are you sure that reading the register should gain the value write to it before? Often, the semantics of device registers are different from this assumption.
