Web interface¶

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 &

With firmware running, you can access the camera using URLs below (192.168.1.10 is the default IP address):

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

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

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 \

    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

#!/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.

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¶

0x000000000000-0x000000040000 : "boot"
0x000000040000-0x000000050000 : "env"
0x000000050000-0x000000250000 : "kernel"
0x000000250000-0x000000750000 : "rootfs"
0x000000750000-0x000001000000 : "rootfs_data"

Kernel Memory Load Addresses¶

loadaddr-$(CONFIG_TARGET_hi35xx_16cv100) := 0x80008000
loadaddr-$(CONFIG_TARGET_hi35xx_16cv200) := 0x80008000

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:

tftp 0x82000000 openwrt-hi35xx-XXXXX-u-boot.bin
#
fatload mmc 0:1 0x82000000 openwrt-hi35xx-XXXXX-u-boot.bin

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¶

flashcp -v openwrt-hi35xx-XXXXX-u-boot.bin boot

or

flashcp -v openwrt-hi35xx-XXXXX-u-boot.bin /dev/mtd0

Update kernel¶

flashcp -v openwrt-hi35xx-XXXXX-default-uImage kernel

Update rootfs¶

flashcp -v openwrt-hi35xx-XXXXX-default-root.squashfs rootfs

Configuring system after installation¶

Format overlayfs partition¶

Must be executed on first run

flash_eraseall -j /dev/$(awk -F ':' '/rootfs_data/ {print $1}' /proc/mtd)
reboot

Installing the original MAC¶

U-boot ENV and Linux UCI

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

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

firstboot
reboot

Clean u-boot env¶

Restore to default u-boot env
