IMX6 QUAD- Should NVCC_EIMx & NVCC_LCD be same voltage?

Hi Team,

In our new Dual camera project, we're interfacing 2 cameras with YCbCr-16 parallel interface to CSI1 and CSI2 ports of IMX6 Quad processor.

 

We're using 3.3VIO voltage for both of these camera signals.

So, NVCC_CSI, NVCC_EIM0, NVCC_EIM1, NVCC_EIM2 are all connected to 3.3V.

 

The OLED we wanted to connect had RGB-24 interface with 1.8VIO voltage.

So, we thought of connecting NVCC_LCD to 1.8V and use DISP0_DATA00 to DISP0_DATA23 signals and associated lock and sync signals which come under NVCC_LCD power group.

But when I set NVCC_LCD as 1.8V in Pins tool which I use for pin planning, a warning was shown mentioning "Power Group conflict".

 

Please explain to us why this warning.

Please confirm if we can use display signals at1.8VIO setting NVCC_LCD= 1.8V.

 

Thanks in advance.

Emil
