        Have you checked that the MISO signal is connected correctly between the display and the Duet, and that CS0 on the Duet is connected to SD card CS on the display?

        Is it a known good SD card?

        SD card socket on PanelDue works, so it's unlikely to be a firmware problem IMO.

          @dc42 yes, checked fine all connections and try with three sdcards working fine.

          I will test in other duet.

            @seraser I've no personal experience with what is necessary to get an external SD card reader working in RRF, since I print via the network, but since there is no card detect pin, have you tried an M21 P1 "Initialize SD card" or a M39 P1 S2 command yet?

              To clarify: the M21 P1 command is needed to initialise the external SD card after it has been inserted; however, DWC will issue this command automatically if you try to list jobs on the external SD card.

                @dc42 @Schmart finally some progress.

                I can see in web interface sdcard1 not mounted in jobs.

                I can choose and mount.

                When is mounted I can choose files in 12864 from sdcard0 not sdcard1.

                With web interface I can choose files in sdcard0 and sdcard1.

                I do not know if this is right or system need detect automatic at boot but 12864 cant read sdcard1.

                Thanks for support.

                  And for finish to me, from wiki I can play with M20 and M21 for mount and choose files in sdcard1 by editing files in menu folder so all is perfect thank you @Schmart for your work.

                    @seraser I'm glad to hear it's now working for you! And this thread will be a good reference for people who also want to use the SD card reader on their Fysetc display.

                        Just a little compilation of previous info for Duet 2 (according to RRF 3.2 Pins_DuetNG.h) and Ender 3 LCD connected via EXP3:

                        The only one thing working not as expected - M300 S3nnn does not change frequency in my setup. Though I did not checked it with stock...

                          @Swift-Tester not all tweeters can vary their frequency.

                              @swift-tester does it work with RRF 3.3?

                                @matixyo nothing changed here since RRF 3.2, so it should work.
