GPIO resource busy error

[rameshprakash]

Hi,

I am very interested in high speed toggling of GPIO pins ( ~2.5MHz) to use this as a turn on/off clock Found out this PyBBIO supports it - since it uses the kernel method - to do it

I followed the directions installing the pybbio. I tried the blink.py - it worked flawlessly. As I was interested in finding out the maximum speed - this GPIO could toggle - tried executing the speed_test.py - however this showed the following errors

debian@beaglebone:~/PyBBIO/tests$ sudo python speed_test.py
*Could not load gpio1_6 overlay, resource busy
*could not configure pinmux for pin GPIO1_6

Please help me with this

Thanks,
