So the update should not take more the 5 Minutes.
Also will want to update uboot before
That’s a uboot bug, the fixed version can be downloaded here .
Upgrade uboot by the following steps:
- connect LAN and PC by ethernet, the PC’s ip should be 192.168.1.x
- push the reset button and power it on, about 10 seconds later release the button, until the wifi led stops flashing and the white led turns on.
- access http://192.168.1.1/uboot.html to flash uboot.
