HummingBoard Hailo-15 AIOT - MIPI DSI Screen Not working

1

Hi,

I have the Hailo 15 EVB kit with the MIPI-DSI display. The board is working fine.

But the display that has come with it does not show anything, after successful boot process the display’s backlight is ON but nothing shows on it.

Kindly help in resolving this issue.

Linux Kernel and os-release info -
5.15.32-yocto-standard
NAME=“HAILO Hailo-15”
VERSION=“1.7.0”
RELEASE_REV_METADATA=“/etc/hailo-rev”

can you please post your dmesg output with the display attached?

Here is dmesg output file -

It is not detecting the panel. Can you please just double check the ribbon cable and make sure it is securely connected to the board. Sometimes they can be slightly askew and not make good connections across all the pins. If that doesn’t make a difference I will provide additional debugging steps.

Thanks for the reply.
But I have checked the connections it is physically connected via the ribbon cable and the pins are also in correct order.
I can see the back-light turn ON when i power ON the board.
