Hello,
We have a custom board replicated from i.MX8QXP, I am facing the issue in U-boot to prove the LVDS driver.
Following are the boot logs:
BuildInfo:

Boot: MMC0
DRAM: 1022 MiB
setup_typec lookup GPIO5_9 failed ret = 3
MMC: FSL_SDHC: 0, FSL_SDHC: 1
Loading Environment from MMC... OK
[*]-Video Link 0probe device is failed, ret 3
(1280 x 720)
[0] dpu@56180000, video
[1] lvds-channel@0, display
[2] lvds-to-hdmi-bridge@4c, video_bridge
In: serial
Out: serial

Can you please let me know, how to debug the issue?
Thanks & Regards,
Kailas K.
Hi kailas_kharse
seems lvds is not supported in U-Boot 2020.04-5.4.24-2.1.0, one can
try to port it from ver. 2019.04_5.4.3_2.0.0, function enable_lvds()
Best regards

Hello Igor,
I am working on U-Boot 2020.04-5.4.24-2.1.0 Which works fine on MEK, But Not working on Custom Board, I am able to get the Splash Screen in U-boot on MEK.
But in Custom Board I am getting the below error.
MMC: FSL_SDHC: 0, FSL_SDHC: 1
Loading Environment from MMC... OK
[*]-Video Link 0probe device is failed, ret 3
(1280 x 720)
[0] dpu@56180000, video
[1] lvds-channel@0, display
[2] lvds-to-hdmi-bridge@4c, video_bridge
In: serial
Out: serial
Err: serial
switch to partitions #0, OK
mmc0(part 0) is current device
flash target is MMC:0
Thanks & Regards,

Hi kailas_kharse
for that release one can try to debug function imx8_ldb_probe() in imx8_lvds.c
