Enabling MQTT with a ESPHOME configuration the device will immediately crash on boot. Have tried multiple MQTT configurations options to try and make sure there is no configuration issues but as soon as MQTT is enabled immediate crash on boot.

ESP32-S3 display reboots into old firmware after successful flash

Tomas — Sat, 09 May 2026 08:00:12 +0000

I can flash firmware over serial (COM3) and the panel goes black during flashing, so the write process seems to start correctly.
However, after reboot, the display comes back with the previous/old UI instead of the new minimal test UI.

What I have already tested:

Only one* display is connected (COM3).
Serial flashing completes without obvious cable disconnect issues.
I tested a very small minimal firmware/config to rule out application complexity.
The issue is still that after restart, old behavior/layout appears.
Could you please advise:

Is there any known boot fallback/rollback behavior on this display + ESP32-S3 combination?
1. Are there required power/reset/boot pin sequences after flashing?
2. Are there known constraints for RGB timing/pins that could cause app boot failure and fallback?
3. Is there a recommended “factory clean flash” procedure for this board?
4. Should I use any specific partition table or flash settings for stable boot with this panel?
5. If useful, I can share full logs and my exact ESPHome display pin mapping.

Thanks in advance.

DIE07300S : CrowPanel ESP32 4.2” E-paper HMI Display - Elecrow Wiki

I recently purchased the CrowPanel ESP32 4.2-inch E-Paper Display, which uses the SSD1683 driver IC. I’m trying to integrate it with ESPHome but have been running into issues.

What I’ve Tried So Far:
• Used the waveshare_epaper component in ESPHome, which supports SSD1680 (a similar driver).
• Tried different models (4.20in-bv2, 4.20in-bv2-bwr) in ESPHome.
• Adjusted reset durations and power cycled the display.
• Verified SPI pin connections match the CrowPanel documentation.
• Checked logs—ESPHome recognizes the display, but operations are very slow (Component display took a long time for an operation (157ms)) and no image updates.

Questions:
1. Has anyone successfully integrated this CrowPanel SSD1683 e-paper display with ESPHome?
2. If so, which settings or custom drivers did you use?
3. Would a custom ESPHome driver be needed for SSD1683, or is there an alternative workaround?
4. Has anyone tried controlling this panel with the GxEPD2 Arduino library instead?

Any guidance, YAML examples, or alternative approaches would be greatly appreciated. Thanks in advance!
