In VSCODE I select PSRAM enabled and also chosen MALLOC_CAP_SPIRAM so ps_malloc must be used.

psramInit() fails.

when I right click on the function name and select GOTO DEFINITION it shows me this function!

bool psramInit() {
return false;
}

a hard coded fail... when I look into it further up in the file a few lines it due to the fact that
neither conditions are met #if CONFIG_SPIRAM_SUPPORT || CONFIG_SPIRAM

when they are clearly selected SDK Config Editor, I click SAVE and clean build and compile and the same thing.

Anyone experience this?

Also to note:

And this is even after configuring SPIRAM enabled at boot.

Even though Serial.println(heap_caps_get_largest_free_block(MALLOC_CAP_SPIRAM)); reports 4M

on the first call to ps_malloc(x) it will return NULL!

Have you tried heap_caps_malloc(...)?

Yes, and same result.

Fact is the initPSRAM() is returning FALSE... so until it returns TRUE I think they will all not work

For ESP32S3, you may need to specify the mode.

I am using VSCODE but the setting are almost the same
