### Upgrading from the GitHub latest release.
By default, running sysupgrade will attempt to download the latest software for your camera model from the github sources.
There are other options available such as pointing to your own online .tgz file or a local copy of the Linux kernel (uImage) and camera software (rootfs.squashfs)

For old firmware running `sysupgrade` without parameters is enough. For newer firmware, run `sysupgrade -k -r` to update both kernel and rootfs is required
__ATTENTION! Upgrading firmware can lead to "bricking" your camera. Make sure you are prepared both morally and skill wise. Have your rescue SD card and/or UART adapter ready. Be prepared to de-solder and reprogram flash chip as the last resort. Do not upgrade production cameras unless you really have to!__

If you have built your own versions using a copy of the [firmware repository](https://github.com/OpenIPC/firmware) then your uImage and rootsfs.squashfs images will be in your _output/images_ folder. Copy these to the root of your tftp server.
#### On the camera:
You can either update the images from a Linux terminal session or from the U-Boot prompt if you have a UART serial connection and interrupted Linux loading.

Check that your camera environment variable for the TFTP server is correct by looking for the _serverip_ entry when listing them with _fw_printenv_.
If it needs updating use _fw_setenv serverip <your.tftp.ip.address>_ command.
