Dear all,
I'm new to the forum and this is my first question, here is the situation : I've developped a specific board from sabresd schematics and Android software with kernel version 3.0.35. On this board i connected a WIFI module (WL1801) whose IRQ pin is linked to DI0_PIN4 pin, i use the others pins of DISP0 connected to a TFT LCD (data + clock+ hsync + vsync + drdy). I've configured DI0_PIN4 as GPIO (MX6DL_PAD_DI0_PIN4__GPIO_4_20) but after booting i notice a stable clock signal on that pin (around 13.5MHz) whatever the pin is configured (i've tested AUD6_RXD & IPU1_DIN0_PIN4 as well) as there was something coming above pin muxing configuration.
Has someone already faced this kind of problem please ?
With my best regards, Patrick.

Hi patrick
I would suggest to set iomux register using memtool and check once more,
it should work:
