Hi All,

 

I am not able to find how the GPIO number is calculated.

I want to export the GPIO4_09 pin in linux user space considering T1042 Processor Pin diagram .

I have done the calculation for IMX series which are like :

GPIO0_5 --> Linux number is 0*32 + 5 = 5.

 

Can some one post the formulae for QORIQ T104x Series.

 

Thanks in Advance.
