so you downloaded M5Burner correct? and it opens ok?
what exact model of M5Stick you have - you need to choose correct firmware version.
is your M5Stick com port detected in M5Burner when usb is plugged in to M5Stick?

Sorry!! My Bad.
[LVGL8.4] lv.get_target() --> [LVGL9.0] lv.get_target_obj()

slider : Still odd.

** testing LVGL python examples in the middle way. So far so good.

@felmue Thanks for your reply.
Meanwhile I confirmed being powered by POE has no effect. The problem is the interface never gets an address from the DHCP server.
With a fixed address, everything is fine.
Did you try any other Ethernet lib?

Thanks.
