Hello

 

I'm trying to get the ADV7180 working with the Bluechip Technologies RM3 based on the quad core i.mx6.


I'm using Yocto with the Bluechip layer for the RM3.

 

I have connected:

 

P0-P7  on the ADV go to IPU1_CSI0_D_13-19 (I think)

LLC to MX6Q_PAD_CSI0_PIXCLK__IPU1_CSI0_PIXCLK

VS/FIELD to MX6Q_PAD_CSI0_VSYNC__IPU1_CSI0_VSYNC

HS to MX6Q_PAD_CSI0_MCLK__IPU1_CSI0_HSYNC

RESET to MX6Q_PAD_NANDF_CS2__GPIO_6_15

INTRQ to CAM_IRQ (not that I think this is used)

PWRDWN to MX6Q_PAD_CSI0_DATA_EN__GPIO_5_20


With adv7180.c as is the tvin unit test times out.

However if I set p->u.bt656.clock_curr = 27000000; as mentioned in another post on this forum I get the image below.


Anyone seen an image like this before?

I think it could be today with EAV SAV not being read? But I'm new to bt656 and I'm not sure how to check!
