Toggle i/o bit on iMx6 .. ??

To toggle an i/o bit on iMx6 I believe i need to:

1: ensure I can write to GPIO block

2: set the pad ctl register to e.g.0x1b0b0

3: set the pad mux register to the correct alt to route the bit there

4: set relevant gpio dir bit to 1

5: write 1 or 0 to the right gpio data register bit

 

have I missed anything, e.g. clock enable? or anything else?

 

Thanks

 

John
