CrowPanel Advance 7.0 (V1.4 hardware) - Black screen after flashing pre-compiled bin #2777

Hello!

I just flashed the pre-compiled bin: elecrow_crowpanel_advance_70_companion_radio_lvgl-0.4.4-0fe6159-merged.bin via the ESP Web Flasher.

The flashing process completes successfully with no errors, but the screen remains completely black and won't turn on. I have the Elecrow CrowPanel Advance 7.0 Version 1.4.

It seems Elecrow might have changed the display pinout or the backlight routing in this specific hardware revision. Would it be possible to add support or generate a specific .bin for the V1.4 boards?

Thank you for all the great work on this project!
