DISPLAY issue on DM8168

Hi All,

ARM is requesting the get_display INIT than it is looping over here(The same code is working for EVM board).

Below I am mentioned code snippet.

mcfw/src_linux/mcfw_api/usecases/multich_common.c

status = System_linkControl(                ------------------------------ this function is not returning on Our custom board.
        SYSTEM_LINK_ID_M3VPSS,
        SYSTEM_M3VPSS_CMD_GET_DISPLAYCTRL_INIT,
        &(*prm),
        sizeof(*prm),
        TRUE
        );

With Regards

Are you using DVR RDK . Which DVR RDK release are you using ? Also which usecase are you running.

Hi,

DVRRDK_01_09_00_19 - software version

0.5A --- hardware version.

use case : Entered usecase 16CH Progressive <816x> Cap/Enc/Dec/Dis

The Code is working fine for Evm kit but Same code is not working for our custom board.

How to proceed ?

gSystem_objVpss.hdmiHandle = FVID2_create(FVID2_VPS_VID_ENC_SII9022A_DRV,
                                                                            0,
                                              &encCreateParams,
                                              &encCreateStatus, NULL);

Here it is hangs.

In what scenario it will hangs ? at-least it must fails means it has to returns.

Do you have SII9022A populated on your board ? Also is the i2c address to control the SII9022A the same on your board as it is on the EVM. From your descritption it looks like i2c control from M3 is hanging because the i2c address is invalid on your board. I would recommend you migrate to latest DVR RDK 3.5 release where the video encoder configuration is moved to HLOS side where you can write board specific code for video encoder configuration without having to modify M3 code.

Hi ,

For on chip and off -chip HDMI SII902A I2C interface is needed?

we are using only on chip HDMI and not using offchip HDMI.

is on chip HDMI also needs SII9022A I2C interface? if not please let me know how to configure on HDVPSS side

Hi,

To disable 9022a configuration in DVR, set the flag enableConfigExtVideoEncoder to false in the filke ti_vdic.c.

Thanks,
