          Not sure if this is the right place to report issue, but WiFi doesn't work with this build I don't think.

            I get the message "Android system serial console enabled performance is impacted. to disable, check bootloader." How do I disable this?

              @retroman use adb command and change cmdline.txt (delete console=ttyS0) which in boot partition.
              Or wait for next version image.

                @大法师 I think you meant replace "console=ttyS0" with "console=ttyS1"? Anyway, console=ttyS1 fixed it.

                    @大法师 Thank you, but please provide onedrive link or some other link because I can't download from baidu. Does this version also support bluetooth? In addition, does this version enable the use of the top USB3.0 port? The old version makes the the top USB3.0 port unsuable.
                    Thank you!

                      also use onedrive link(https://1drv.ms/u/s!AhSBNZjrDPlSanDDQF7WowYhiz8?e=lRpMrk). And then the top u3 port is used for adb debug.

                          Hello! Thank you for working hard during your Chinese New Year! I don't want to bug you on your break, but when you get a chance can you enable bluethooth on Android? I really need bluetooth for my project. Thanks!

                            @retroman Bluetooth feature has been added to support. I will upload a new image file (20230118) to onedrive.
