I have a similar issue. My UHF RFID reader (JRD 4035) wont work on the Atom lite. I have been tinkering all day with no luck. Maybe the example code provided is outdated?

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
