i.MX 8QuadXPlus - MEK Default configuration and files "out-of-the-box"

[viniciuscarvalho]

Hello,

I would like some help to find/have the files and the setup procedure to return my development board as it was "out-of-the-box":
i.MX 8QuadXPlus Multisensory Enablement Kit | NXP Semiconductors

I couldn't find the files and the procedure to do it.

I have a HW B0 revision/version.

I'm trying to make it run with a LVDS-TO-HDMI bridge but I get no video output (nothing, no console, no blink, no noise, nothing). I would like to test if the LVDS-TO-HDMI bridge is burned or if I'm missing some configuration.

I already sent succefully the NXP image for Embedded Linux, Android and Android Automotive OS that are compatible with B0 revision.

The LVDS-TO-HDMI bridge is keeping the RED LED always ON and the GREEN LED after the kernel starts up.

From the COMM port I can see the "lvds-to-hdmi-bridge@4c" is being recognized by U-Boot.

On Embedded Linux, running on SD CARD, the kernel is initializing until it requests the login/password (root by default with blank password).

I can navigate into the folders "/dev", etc ... no problem.

Can anyone help me with that?

Thank you very much!

facing the same issue with imx8qxp c0 mek. android boots fine facing display not coming up only with android automotive

[viniciuscarvalho]

In my case I can't see any video output, not even noises on the screen.

Hello, thanks for replying.

Android Automotive OS:
automotive-12.0.0_2.1.0_image_8qmek_car2

If I perform the boot procedure without setting:

setenv bootargs console=ttyLP0,115200 earlycon init=/init androidboot.fbTileSupport=enable cma=928M@0x960M-0xfc0M androidboot.primary_display=imx-drm firmware_class.path=/vendor/firmware loop.max_part=7 transparent_hugepage=never moal.mod_para=wifi_mod_para.conf androidboot.lcd_density=240 bootconfig

The kernel starts and the LVDS-TO-HDMI bridge is turning the led green (but nothing is being display on the HDMI monitor connected to the bridge). After the kernel finishes the initialization I can navigate through the files/folders on the COMM (serial port)... but without video.

If I setenv as ANDROID_QUICK_START_GUIDE I don't have video, the LVDS-TO-HDMI bridge green led doesn't turn ON and the board keeps restarting during the kernel start-up (please see attached log).

I don't know what to do.

I would like to have the default files and configuration as "out-of-the-box" to check if my HW is OK.

Hi

Can you share which BSP you are facing this issue?

For Android OS, please refer 9.4.1 Booting with single LVDS-to-HDMI/MIPI-DSI-to-HDMI or dual LVDS-to-HDMI displays in  https://www.nxp.com/docs/en/quick-reference-guide/ANDROID_QUICK_START_GUIDE.pdf

The LVDS-TO-HDMI bridge green LED turns ON but nothing is happening on the HDMI monitor.

[NajiyaNazrin]

Hi , I'm facing the same issue here. Im using IMX8QUADXPLUS  and HDMI output is not showing . Is the issue resolved for you? @viniciuscarvalho 

[viniciuscarvalho]

No, I bought a new LVDS-TO-HDMI converter to test it. But, I don't think that the problem is the HW.
