RK055HDMIPI4MA0 Jumpers

mpocius — Mon, 15 Aug 2022 15:08:44 GMT

Is there a document that has the schematic, or at least just the jumper configuration information, for the RK055HDMIPI4MA0 LCD board? I got a couple to interface with RT1160 and RT1170 EVK boards, but I couldn't find any info on the RK055HDMIPI4MA0 besides the datasheet, which doesn't document what the jumpers do.

I am asking if we have some data about it, but that information can be provided by the designer display Rocktech

I'm also wondering what the purpose is of these extra jumpers as there are already jumpers on the display. The photo below shows the extra 6 jumpers (in a small plastic bag) and the jumpers already inserted on the left side of the display:

Perhaps the display is already set up correctly and the extra jumpers are just spares?

Also, can someone please confirm if the ribbon cable is inserted into the MIPI LCD connector on the MIMXRT1160-EVK as per the photo below? I'm assuming pin 1 and pin 40 on the display connect to pin 1 and pin 40, respectively, on the MIMXRT1160-EVK but wanted to make sure the orientation is correct before applying power:

Actually, I had it upside down. The correct orientation is:

The "elcdif_rgb_cm7" SDK example works, so it appears the extra jumpers are not needed when the display is used with the MIMXRT1160-EVK:

Hello @CarlosGarabito

The schematic is very useful and clears up quite a few things. Is is possible to share the design files for the display board too? Its mostly to get the placement of connectors right on our custom board that uses a similar display.
