Yocto Unified Firmware Upgrade

The compiled firmware is located in <path/to/yocto>/build/tmp/deploy/images/<board>/. The files to download are .wic and update.img. After entering loader mode, execute the following commands:

$ sudo upgrade_tool wl 0 <IMAGE NAME>.wic
$ sudo upgrade_tool uf update.img

• The default login account of the firmware is: root, password: firefly. The firmware contains a common user account named firefly, and the password is firefly.

If you are developing on a Windows PC, you can use RKdevtool to directly burn update.img, without burning <IMAGE NAME>.wic. Note that update.img is a link file, so select the actual file that the link points to.
