How to change to high level trigger?

[jiangshao]

I want to use a GPIO on imx6 sabre_sd as INPUT(default), the default is low level trigger,

how to change to high level trigger?

[igorpadykov]

Hi jiang

default (after reset) levels are defined in

IMX6DQCEC  Table 100. 21 x 21 mm Functional Contact Assignments

they can not be chaged, this is fixed in hardware. One can change them later in Uboot or

Linux.

Best regards

igor

Thank you for your reply.

I know I can change it , but I want to know how to change it,

such as whether I can set it in the board-mx6q_sabresd.c or gpio.c ?

[igorpadykov]

I think better option board-mx6q_sabresd.c
