I am using a 13-inch DUDU7 device. When a new version is released on the DUDU6 7862 device, all data on the device is deleted and twipe_all is used in the updatecfg file when installing. However, formatdata in the DUDU7 updatecfg file does not completely delete data in the device. Is there a way to delete all data in the internal memory of the DUDU7 device and install a new version?
