Hello, Krescue can be used to flash the Edge-V from SD card. Power, HDMI and Lan need to be connected. You can navigate Krescue with the Khadas IR remote or connect a USB keyboard prior to booting. I can help you with using Krescue.
Regarding USB-C flashing. NOTE: Remove any SD card occupying the SD card slot. See the image below, the indicated USB-C port must be used when USB-C flashing.
Once tha Android Tool is running and the USB-C cable connected to the indicated USB-C port, update mode(TST mode) can be entered by pressing the Function button 3 times in under 2 seconds. If successful, you should see something like this…
Do you see that?
If not let me know.
Regarding the Driver Assistant… Use it to uninstall the driver and reboot your PC. Using the Driver Assistant, reinstall the driver and try the Android Tool again. Otherwise, check cable. Also some have mentioned that in addition to using the USB-C port indicated for the upgrade cable(data), extra power can be applied to the other USB-C port(PD).
