Hi All,
Has anyone got the ADV7181C working with i.MX6? I want to capture VGA signal with ADV7181C.
Would anyone share the code with me ?

Hi Igor,
I had already patched my kernel from that post, but it didn't work.
IPUx_CONF (0x02600000) : 00000665
IPUx_CSI0_SENS_CONF (0x02630000): 0200C97B
The error message is:
TV decoder chip is adv7181c_decoder
ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0
VIDIOC_DQBUF failed
for ADV7180 mxc_v4l2_tvin should be used, there are some examples on
Patch to support adv7180 TVin chip for Freescale Android R10.4 BSP on iMX53 -blog archive

Any advice? Thanks!!!
Hi Gang
ADV7180 is supported on Sabre AI boards so suggest to test on that board
SABRE|Automotive-Infotainment|i.MX6|NXP

Hi igor,
Thank you for the reply!
But I want to capture a VGA picture by adv7181c, which ADV7180 does not support.
Hi igor,
My test app is copy from mxc_v4l2_tvin.c, i had tried mxc_v4l2_tvin, it failed too. I don't think this is the problem, I think there must be something wrong with the kernel or the driver, would you please give me some advice, thanks!
