Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

Good day Very new to ESP 32. Trying to upload your sketch to a ESP32 Cam AI Thinker and receive this error message while compiling.

@Jakes4050 I think this problem is unrelated to esp-iot-solution, it's a general esp32-arduino Migration from 2.x to 3.x questions.

Your Arduino project ESP32-CAM_MJPEG2SD.ino using esp_spiram_get_size, which is an ESP-IDF v4.x function (Arduino 2.x based version), please Install esp32-arduino 2.x version instead in your project.

Or, you need to port the project from esp32-arduino 2.x to 3.x (based on ESP-IDF 5.x).
