DM365 IPNC RDK LCD Display

Hi,


I am using IPNC RDK 5.1.0 and DM365 EVM. I want to display data on LCD.

1. Will it be possible using V4L2? As I can see the RDK is not having the Davinci Encoder Manager which is present in the SDK. Should that be an issue?

2. I want the data to be output in PRGB 888 format. For that I have set the required registers of VENC and OSD in the Video Encoder of VPBE? Should that be enough? As I can see the davinci fb file is not being compiled. Will that be required?

We do not have the LCD yet but when I boot the board with this uImage and run the moduletest for drv_display, I cannot see any signals on the LCDout lines on probing there. I have set the pinmux correctly for all 8 R, G and B lines.

Please guide me on what I  should do to get the LCD display working. I can display composite on TVOUT just fine.

Regards,

Charvi.

    Charvi, I have a feeling we're working on the same thing from the other end (if you're working on a really wide, really short display, then the answer is yes); but I think the short answer is no; the V4L2 only seems to support an analog output (or analog with overlay); and every example I've found seems to think it's support RGB by using one of the VPBE OSD layers; which is not what we want (we want RGB output). That said though, I would be curious to know what you changed in the VENC/OSD settings; because I'm about to go into hacking mode to get this working; and that might be a good place for me to be looking- I got hung up in platform_device_register but sounds like you made it through the woods on that one... a kick might get me able to help us all get through this.
