Hi
Following the Wiki instruction I try to update the flash program of the respeaker lite itself (not the ESP) but it doesn’t work.
dfu-util sees the device but can’t access it. I have rebooted after doing the modifications indicated by wiki for usb access in linux !

Side note: the board doesn’t show up as audio interface in Linux although it should according at documentation.
