TDA2EVM5777: Vision SDK and LCD

Ganesh H

Part Number: TDA2EVM5777

Hi,

Why Vision SDK gives output only on HDMI why the output can't be given to LCD? When we are using Vision SDK which core has control of DSS?

As per this block diagram if we set that MUX correctly we can show the TV output to LCD1/LCD2/LCD3 . Is this achievable using Vision SDK?

Vision SDK has 2 varients

1. VSDK Bios only - where all cores running BIOS

2. VSDK Linux - where A15 running Linux and rest all cores running BIOS

In fisrt case VSDK support both HDMI and LCD

In second case, as of today we support only HDMI, This is a SW limitation, no issue with HW.

In both cases the DSS is controlled from M4 (IPU)

regards, Shiju
