ESP32 Forum

I am testing an ISR on an ESP32-DevKitC equivalent (JZK ESP-32S ESP32) using Eclipse Arduino. I am running on Windows 10.

I've run the test programs successfully using the Arduino IDE (for example this one: https://techtutorialsx.com/2017/10/07/e ... nterrupts/). I have also run the gpio program successfully from the esp idf.

With the Eclipse Arduino plugin I get the "[W][esp32-hal-psram.c:30] psramInit(): PSRAM init failed!" error at startup.

I've reported the issue to Jantje here: https://github.com/Sloeber/arduino-ecli ... ssues/1007. He suggested that I check with this forum to see if this is a known issue and if there is a solution.

I thought that the issue might have to do with the PSRAM problem reported here: viewtopic.php?t=2031 and here: viewtopic.php?t=2967. However I have no idea if this is the problem and if it is, how should I go about fixing it on the Eclipse Arduino.

Does your board actually have psram? (The actual esp32-devkitC does not.) It may be that Arduino is configured to use it if it's there, but ignore it (but still warn the user) if it's not.

I apologize for the late reply ... I didn't get notification of your reply.

No, I guess the Wrover DevKit C does not have PSRAM ... I think there's a setting somewhere to turn off notification of this error.
