about changing pinmux settings of DM8148

HI,all

I am working on DM8148 , I would like to change pinmux function of GMII0_TXD0-7 to GPMC_A[7...14](PINCNTL250-PINCNTL257).

I tried two ways but failed:

1  I change the "bit()" in mux.h in u-boot dir, but failed.()

2 I use the omap_mux_init_signal() function in the kernel to change the pinmux function but also failed.

do I miss something? Do I have to change the menuconfig or something else? is there any user guide document? how to solve this problem?


by the way, I can change the gpio0_1-gpio0_4 pinmux function using the method 1, why?

Thank you ahead of time. I need your answer the soon the better.

Best Regard,
