2009-07-18 11:18:11     PORTMUX and PORTFER Configuration doubt

Hi,

 

I am working with 2009R1-RC1 distribution with BF527 based custom hardware.

 

I need to configure the PORTMUX and PORTFER registers according to the custom board design.

 

I would like to know how these registers are handled in BF527 Ezkit.

 

please suggest me where i can initialise them properly.

 

Thankyou

Sreedhar:

 

You should never touch any of those registers. It should be handled inside the drivers.

 

If you have problems with anything - let us know,

like Robin said, use the gpio/portmux framework.  never touch those registers yourself.
