I am using beagle bone black board with AM335X Processor from TI and have a JTAG adapter and use OpenOCD and ARM GDB to connect and read and write to memory. I am trying to read registers of GPIO 1 to set a register with value to see a LED glow. I tried to read certain registers from GPIO 1 and found that all the values are 0 and when I write to the DATAOUT register it says "Cannot write to register"
Any suggestion on this is apprecitated!
Thanks. Venkat
