### Web interface
* [http://192.168.1.10](http://192.168.1.10) - Standard system interface based on OpenWrt Luci
### Majestic streamer
Majestic is a video streaming application, the heart of our firmware (in
relation to camera/video surveillance functionality). It's configurable
via file `/etc/majestic.yaml` and by default has many features/services
enabled. Unneded options can be turned off for better security and
performance.
To run `majestic` in debug mode:
```
killall -sigint majestic; export SENSOR=$(ipctool --sensor_id); majestic
```
To run `majestic` in production mode restart the camera or run command:
```
killall -sigint majestic; export SENSOR=$(ipctool --sensor_id); majestic 2>&1 | logger -p daemon.info -t majestic &
```
### Camera related URLs in firmware
Information on the streamer URL's and their description can be found in the [Wiki](https://github.com/OpenIPC/openipc-2.1/wiki/majestic_streamer)
### Statistical data
Software might do product usage data collection including SoC and sensor model name to gather statistics used in QA process.
We guaranty that the data is fully anonymized, and does not contain anything that can arguably be considered data about an individual, that could be considered end-user data; or that could be sensitive or confidential to users.

### Releases
The **releases** of the OpenIPC firmware is hosted at https://github.com/OpenIPC/chaos_calmer/releases
### Source code
The **source code** of the OpenIPC firmware is hosted at https://github.com/openipc/chaos_calmer
## Building from source
### Build on Linux machine
Usage example for Debian 8/9
```bash
git clone --depth=1 https://github.com/OpenIPC/chaos_calmer.git OpenIPC
cd OpenIPC
./Project_OpenIPC.sh update
./Project_OpenIPC.sh 16cv300_DEFAULT
```
### Use Docker for building
**Default Dockerfile.openipc**
```docker
FROM debian:stretch
RUN DEBIAN_FRONTEND=noninteractive apt-get update \
&& apt-get --no-install-recommends -y install bc bison build-essential \
ca-certificates cmake cpio curl dos2unix file flex gawk gcc-multilib \
gettext gettext-base git intltool libc6-dev liblocale-gettext-perl \
libncurses-dev libssl-dev locales mc openssl python rsync subversion \
time tofrodos unzip upx wget zlib1g-dev \
&& localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias \
en_US.UTF-8 && rm -rf /var/lib/apt/lists/*
ENV LANG en_US.utf8
WORKDIR /src/openipc
RUN git clone --depth=1 https://github.com/OpenIPC/chaos_calmer.git /src/openipc
RUN ./Project_OpenIPC.sh update
RUN ./Project_OpenIPC.sh 18ev200_DEFAULT # <= Change this ID to you profile
```
**Start building**
```bash
#!/bin/bash
docker build -t openipc -f Dockerfile.openipc .
```
## Preparing to install
### Get access to U-boot
Serial (UART) connection to your camera device is required.
* CamHi | Press **Ctrl+C** in U-boot start and access password - HI2105CHIP
* Dahua | Press **Shift 8** in U-boot start
* JVT | Press **Ctrl+Q** in U-boot start
* XM | Press **Ctrl+C** in U-boot start
* SigmaStar | Press **Ctrl+B** (UNIV) or **Enter** (Anjvision) in U-boot start
### Backup original MAC
You should definitely write the original MAC of your device on the eth0 port.
This is **important** and will be necessary at the final stage of device configuration.
### Backup original firmware

### Flash and memory layout
We have developed a universal partition system for camera flash chips
and it is now available as standard for all types of devices. (Note
that it means it likely doesn't match vendor flash layout.)
#### OpenIPC flash layout
```txt
0x000000000000-0x000000040000 : "boot"
0x000000040000-0x000000050000 : "env"
0x000000050000-0x000000250000 : "kernel"
0x000000250000-0x000000750000 : "rootfs"
0x000000750000-0x000001000000 : "rootfs_data"
```
#### Kernel Memory Load Addresses

## Flashing new firmware
**Attention !**
All examples indicate the download of firmware components via the TFTP server.
If your device does not have an Ethernet port, replace in all lines the **tftp** command everywhere with **fatload mmc 0:1** For example:
```txt
tftp 0x82000000 openwrt-hi35xx-XXXXX-u-boot.bin
#
fatload mmc 0:1 0x82000000 openwrt-hi35xx-XXXXX-u-boot.bin
```
### Hi3516Cv100
**This type of board has additional Ethernet control systems via GPIO and registers. Consult with experts !**
**Experimental devices:**

## Updating parts of the firmware
If you already have OpenIPC firmware installed, you can update individual
flash partitions from shell command line:
### Update u-boot
```bash
flashcp -v openwrt-hi35xx-XXXXX-u-boot.bin boot
```
**or**
```bash
flashcp -v openwrt-hi35xx-XXXXX-u-boot.bin /dev/mtd0
```
### Update kernel
```bash
flashcp -v openwrt-hi35xx-XXXXX-default-uImage kernel
```
### Update rootfs
```bash
flashcp -v openwrt-hi35xx-XXXXX-default-root.squashfs rootfs
```
## Configuring system after installation
### Format overlayfs partition
**Must be executed on first run**
```txt
flash_eraseall -j /dev/$(awk -F ':' '/rootfs_data/ {print $1}' /proc/mtd)
reboot
```
### Installing the original MAC
**U-boot ENV and Linux UCI**
```txt
fw_setenv ethaddr 00:01:02:03:04:05
uci set network.lan.macaddr=00:01:02:03:04:05
uci commit
```
### Installing the correct sensor
**Specify your correct sensor, control type, and data bus**
```txt
fw_setenv sensor imx291_i2c_lvds
```
## Resetting configuration
If something went wrong, you can reset configuration to defaults.
### Clean overlayfs (reset)
**Restore to default Linux settings**
```txt
firstboot
reboot
```
### Clean u-boot env
**Restore to default u-boot env**
```txt
flash_eraseall -j /dev/$(awk -F ':' '/env/ {print $1}' /proc/mtd)
reboot
```
### Recover backup firmware
If something goes horribly wrong and you want back your backed up firmware
**Restore backup up firmware via serial**
Install kermit using instructions [**here**](https://glasstty.com/?p=662) or similar.
Here are the sample commands for 8MB Flash
