Title: gpio_init and gpio_para difference in fex files ?
Post by: Mouchon on March 16, 2014, 12:52:46 PM
Hi
What is the difference between gpio_init and gpio_para section in the fex file ?

I ask this because i want change the default settings for gpio at boot time to low output
value. So i need to change the fex entry to do this but don't know if i need to change
it on both section.

Philippe.

After some investigation it seem that gpio_para should be used but the kernel sunxi-gpio overwrite
default input / output state to input  and doesn't take care of what is on the fex file.
