Poor performance when PSRAM is enabled - EMI / Grounding issue #7

Open luc-github opened 4 months ago

luc-github commented 4 months ago

Hello, I using your nice board (lot of cool features) for a project (ESP3D v3.0)but we encountered performace issue when PSRAM is enabled. It looks like a grounding or EMI issue, because issue is solved if we plug the board on breadboard and press the ESP shield on top of PSRAM chip with finger.

This workaround is just a POC of the issue, not a real workaround - the issue happend on boards bought in Taiwan and also in France by another user.

I do not know if it is a design issue or a production issue, but I wonder if you have a rework solution for existing board v1.1 ? or a new board version (1.2? / 2.0?) with a solution that I could mention in notes of my project : https://esp3d.io/esp3d/v3.x/hardware/esp32-s3/freenove/index.html

Thank you in advance for your feedback

Hi, I am the "other user from France" mentioned in OP. Here is the setup that fixes the performance issue (fully pushed into the breadboard)

This is a problem we have not encountered for the time being, and we will try to reproduce and solve it

I have the same issue on Freenove ESP32-S3 WROOM 1.1. Performance drasticaly slow when board stay alone. Sometimes one frame takes during 7-8 seconds. But, performance partially improoved if i take board in finger. I think, it is not acceptable to use board with such issue.

I experienced the same issue when running the example. Also noticed an unusual heat emanating from the CPU shell, which encloses the ESP32 microcontroller.
