iMX8QXP-falied to on LVDS-HDMI display

[kinjalGediya]

Hi NXP,
We are using custom board of iMX8QXP-mek. We are using lvds in it and and we are not able start HDMI disaply.
There is only 1 port of LVDS in custom board which is LVDS0
We removed I/O expander in custom board and give 1.8V externally to MIPI_DSI0_EN pin, remaining things are same like clock and data pins.
We are getting PWM signal in mini SAS daughter board.
Another problem is we are not able to get clock on MIPI_DSI0_I2C0_SCL pin.
Can you please guide us for above issue?

Hi kinjalGediya

one can use it6263 lvds-hdmi bridge example

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8qxp-mek-...

For i2c issue one can try to debug it in driver

https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/gpu/drm/bridge/it6263.c?h=imx_5.4....

Best regards

Hello igor,

Thank you to your quick reply.

I resolve problem of I2C clock for lvds but getting error "it6263 19-004c: Probe failed. Remote port 'lvds-channel@0' disabled" and "it6263 20-004c: Probe failed. Remote port 'lvds-channel@0' disabled."

In custom board there is a direct 5v given to LVDS enable pin.

I also make changes in LVDS driver and in device tree.
Can you please guide us for above error?
