ESP32-2432S028R & openHASP Nightly: Blank Screen (WiFi OK)

[jjlopez8]

Hi everyone,

I'm having an issue with my ESP32-2432S028R board after flashing a nightly build binary from the official page: https://nightly.openhasp.com/.

Specifically, I used the binary designated for the "Sunton 2432S028R" (which uses an ILI9341 display and XPT2046 touch, according to the site). After flashing, the screen remains completely blank. However, I can confirm that the ESP32 itself is working, as I'm able to connect to it via WiFi and access the openHASP web interface.

As a test, I also tried flashing the binary for the "Sunton 3248S035R" (a 3.5" display, also ILI9341/XPT2046) from the same nightly build page onto my 2.8" ESP32-2432S028R. With this 3.5" binary, I do get an image on the screen, although it's garbled with lines, which is expected due to the resolution mismatch (the 3.5" display likely has a different resolution, e.g. 320x480, compared to the 2.8" which is 240x320).

This experiment leads me to believe that my ESP32-2432S028R board hardware is likely fine. It seems the issue might be with the specific nightly build binary for the 2.8" Sunton 2432S028R – perhaps it's not compiled correctly for this display.

Has anyone else experienced a similar blank screen issue with the ESP32-2432S028R using the recent nightly builds from https://nightly.openhasp.com/?

More importantly, would anyone happen to have a known-good, correctly compiled binary for the Sunton ESP32-2432S028R (2.8" ILI9341 display) that they could share or point me to?

Any help or insights would be greatly appreciated!

Thanks!
