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!!!

Hi Alleen
this may be hardware issue, could you try this clock on sabre sd board
with Demo images
Board Support Packages (32)
IMX6_L5.1.1_2.1.0_ANDROID_DEMO_SD_BSP (REV L5.1.1_2.1.0)

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!!!
