Hi All,

I want to porting ov5640 on ours device.

My board use imx6dl and Android 5.0 (BSP : android_L5.0.0_1.0.0-ga_core_source.gz).

And we can't to enable ov5640.

We check the device, and found the GPIO_0 didn't to generate the clock.

But, when we use the android_kk4.4.2_1.0.0-ga_core_source.tar.gz, this pin of GPIO_0 can generate the clock.

So, How can I set the GPIO_0 to clock source ?

Anyone to help me with this problem?

Thanks!!!

BR.

Hi Alleen

GPIO_0 (CLKO) clock is enabed by default, please check if correct

dts file is used, it should have line similar to:

pinctrl_hog_1: hoggrp-1 {  MX6QDL_PAD_GPIO_0__CCM_CLKO1

0x130b0

linux-2.6-imx.git - Freescale i.MX Linux Tree

Best regards

Hi igor,

Thanks for reply.

I know this setting, and we didn't change anything about this.

When we used the default setting, it didn't generate the clock from GPIO_0.

So, besides setting the "MX6QDL_PAD_GPIO_0__CCM_CLKO1", does need to set other settings?

Thanks!!!
