Hi there,
We are working on OMAPL138 LCDK to connect other device through GPIO. I am trying to use GPIO3[0:7] pins through configuring PINMUX8 from DSP end. The pins are available in expansion header J14.
I started with GPIO example from CSL library which is using GPIO0[7] and works as expected. Then I modified the example to use GPIO3[0] (if it worked, I would configure other ports on GPIO bank 3). However, GPIO3[0] was not working (interrupts were not triggered ).
Just want to check
1/ if GPIO3[0] pin and other GPIO3 pins are open for users to use?
2/ Do these pins have to be EMA_D[8:15] which appear in PCB schematic layout?
3/ GPIO8[10] and GPIO[12] appear in J15 expansion header according to PCB schematic layout. but, why is GPIO8 not completely defined in CSL library? Before using GPIO8, I just want to check if GPIO8[10] and [12] are also open for users to use?
Cheers,
Louie
