Firmware 9.9 Specs

Summary

Changes, Updates and New Features

Important! Need to create a single modular Firmware that can work with all old (v5) devices, current boards (v7, v8) and future devices (Idrive X2).

Boot loader and Kernel

Starting with v7 we will use a new boot loader version. The new boot loader can be installed at old v5 boards in the RMA process.

The new boot loader offers new features like: loading kernel and file system from SD card, etc.

Also starting with v7 we have a new Kernel 2.6.24 that is same Kernel version with some modules and configuration for GPRS.

Code Improvements

Single Config File

Needs to be an XML file that contain all info from firmware version to IP, SSID and more.

7/8 stable frames

This firmware version needs to have some 7/8 frame stability like Firmware 9.6. 50 ms delay on power images sensors on will force them to work asynchronous.

Set lower values for SDRAM

According to some tests made by Aurel... Require register set. This will be set by PORTC driver using ioremap.

Sleep Mode

On 9.6 firmware we have 3 modes: Test, Event, Transfer.

The Sleep Mode will be optional by checking a variable in the Config file.

The device will enter the Sleep Mode after Transfer Mode.

Any trigger will wake-up the device and will enter in event mode.

Sleep Mode Initialization

1. Stop the IR Led power (shut the IR leds off)

2. Stop the buffering (video, audio, GPS, etc)

3. Stop both cameras

4. Stop the GPS logger

Sleep Mode Functionality

1. Trigger Events - the device will wake up and start recording from that specific moment = Wake Up Event (24 seconds)

2. Timer - the device will remain in the Sleep Mode 72 hours (this value can be set from Config file), after Sleep Mode and if no IGN ON the device will shut down.

3. If IGN ON the device will enter in Event Mode (without restart)

4. Optional! In Sleep Mode the device can go in Transfer Mode ever hour or so (adjustable from Config file)

Sleep Mode Tests

1. Need to establish the exact current in Sleep Mode.

2. Need to see how fast the Event Mode can be start

3. Need to see how many seconds from the Wake Up Trigger will need to start recording.

New Features

Longer events

Events longer then 30 seconds will take only 15 seconds from video buffer, rest will be real-time video...

G-Force buffering

New thread/class should be use to manage the buffers.

** Tests notes **
100kHz, default bus freq permits acquisition of ~8 values/sec.
Require to set I2C bus at 400kHz - will increase number of reads/sec up to 25.
On verson 5 boards using 400kHz freq creates more noise on image whitch will increase event size by 30%.

GPRS

GPRS - Real Time GPS coordonates and Events data

Will be used http standard requests. Server side Apache/PHP/MySQL. GPS string, ignition and event will be send as parammeters on URL under http request.

GPRS - GSM triggered events (from Idrive Global Center)

Will be used http standard requests. Server side Apache/PHP/MySQL. Event will be triggerd on "SEND PERIOD" since firmware initiate requests. HTTP respond should be parse to get the event request.

Sleep Mode

• shutdown wifi module;

Device consumption in sleep mode 300mA;

Serial Port Features

Require RTS/CTS disabled for serial 1 and set to RX[2], TX[2] - bit [11, 12, 13, 14] to 1010 (0xA) for register:
