How AIO II can use SD FW update?
Well , you can have a look at the github README here
GeorgeFu The linked page says "copy Firmware.bin to root folder on sd card and power on".
Unfortunately it does nothing if I do that. I tried 2 different SD cards already. Is there something else that I need to do to upload a new firmware to the device?
If you follow the README , you should be able to upload firmware, but at worst situation , it may need 2 minutes to finish the loading.
