Upgrading firmware
|
||||
------------------
|
||||
Once the initial installation of the OpenIPC software for your camera is complete it is possible to upgrade it either via the Majestic web interface or manually via a terminal window.
|
||||
|
||||
### Upgrading from GitHub
|
||||
For old firmware running `sysupgrade` without parameters is enough. For newer firmware, run `sysupgrade -k -r` to update both kernel and rootfs.
|
||||
This article is about how to manually perform an update using a terminal window using the sysupgrade command.
|
||||
|
||||
__ATTENTION! Upgrading firmware can lead to "bricking" your camera. Make sure you are prepared both morally and skillwise. 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!__
|
||||
_Note: By default, sysupgrade will reboot the camera to complete the update. If you don't wish to do that then use the -x option (see sysupgrade --help for all options)_
|
||||
|
||||
### Upgrading from a TFTP server
|
||||
### 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.
|
||||
|
||||
[Set up a TFTP server](installation-tftpd.md).
|
||||
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)
|
||||
|
||||
Go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC.
|
||||
Extract content of the bundle into the root directory of your TFTP server.
|
||||
For old firmware running `sysupgrade` without parameters is enough. For newer firmware, run `sysupgrade -k -r` to update both kernel and rootfs is required
|

#### Github: From Linux
|
||||
### Using sysupgrade
|
||||
Typically running sysupgrade will give you the latest release for your camera, as described above, however if you wish to revert to a previous image, or load your own updates, then use any the following options.
|
||||
|
||||
Remember once you are ready to run sysupgrade you must use the syntax </br></br>
|
||||
`sysupgrade --kernel=/tmp/uImage.${soc} --rootfs=/tmp/rootfs.squashfs.${soc} -z` </br></br>where '${soc}' is your camera specific soc e.g. gk7205v300
|
||||
otherwise the Github latest will be downloaded.
|
||||
|
||||
### Using a TFTP server
|
||||
#### On your host machine:
|
||||
If you haven't already got a TFTP server running on your host machine then take a look at the Wiki article [Set up a TFTP server](installation-tftpd.md).
|
||||
|
||||
If you don't already have the uImage and rootfs.squashfs images for your camera then go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC and extract the content of the bundle into the root directory of your TFTP server.
|
||||
|
||||
If you have built your own versions using a copy of the [firmware repository](https://github.com/OpenIPC/firmware) then your uImage and rootsfs.squashfs images will be in your _output/images_ folder. Copy these to the root of your tftp server.
|
||||
|
||||
#### On the camera:
|
||||
You can either update the images from a Linux terminal session or from the U-Boot prompt if you have a UART serial connection and interrupted Linux loading.
|
||||
|
||||
##### From Linux
|
||||
```bash
|
||||
soc=$(fw_printenv -n soc)
|
||||
serverip=$(fw_printenv -n serverip)
|
||||
cd /tmp
|
||||
busybox tftp -r rootfs.squashfs.${soc} -g ${serverip}
|
||||
busybox tftp -r uImage.${soc} -g ${serverip}
|
||||
sysupgrade --kernel=/tmp/uImage.${soc} --rootfs=/tmp/rootfs.squashfs.${soc} -z
|
||||
```

### Upgrading from local files
|
||||
Now restart the camera to load the new images
|
||||
|
||||
Go to <https://github.com/OpenIPC/firmware/releases/tag/latest> and download the latest firmware bundle for your SoC.

Unpack the bundle and upload its content on camera using `scp`:

||||
```bash
|
||||
soc=$(fw_printenv -n soc)
