Hello @M5Judea

hmm, the camera example works for me. Is that the example you are using as well?

It seems that in your case for some reason the PSRAM is not found and without PSRAM there is not enough memory and the code crashes. But why it would fail to detect PSRAM I have no idea, sorry.

Thanks

Hello @M5Judea

further investigation and tests indicate that in your case the incorrect line mode to access PSRAM is used, e.g. opi instead of qspi. I can force the same error in my setup by forcing line mode opi.

That said, the line mode is normally defined via board selection. So my best guess would be that you might have selected the incorrect board? Please double check that you have selected the proper board in your IDE.

Thanks
Felix
