Bootloader
The processor program (firmware) is a set of algorithms developed by GalileoSky Ltd specialists. Owing to
this program, the central processor receives the data from different system units, processes them logically
and mathematically and takes decisions for control commands of controller units to be worked out
depending on the situation.
Bootloader is a Terminal`s sub-programme allowing the main program part (hereinafter referred to as
Firmware) being updated. The firmware can be downloaded from the official site
www.7gis.com . The main
program can be downloaded via the USB or GPRS channel in the Terminal.
11.1 USB channel download
1) Connect the Terminal to the external power supply;
2) Connect the USB cable; the device must be defined on the computer;
3) Launch the Configurator and open the Command mode tab;
4) Type in upgrade 0 command after which the Terminal will be reset in 15-20 sec;
5) After resetting the Terminal will enter the bootloader mode, and the device should be defined as
the system storage device (flash-memory);
6) Download the right firmware version and extract firmware.bin file from the archive;
7) Copy the downloaded firmware.bin file to the flash-memory;
8) After reflashing the device will be reset and enter the operating mode in 15 seconds.
11.2 GPRS channel download
1) Connect the Terminal to the external power supply;
2) APN settings must conform to the inserted SIM card inserted in the Terminal, otherwise, the device
flashing will not happen, and the Terminal will return to the operating mode;
Give the following command: UPGRADE firmware№ using any of the available channels (SMS,
GPRS, USB), where firmware№ is the necessary
firmware version. UPGRADE 0 initiates
downloading the latest firmware;
3) You may see if the flashing is in progress by LEDs blinking;
4)
In 15-25 minutes (depending on connection conditions and GPRS terms of service by operator)
upgrade will be completed and the Terminal will turn into operation mode automatically.
11.3 Using analog inputs to enter bootloader mode
After the device power supply is off, energize all analog-discrete inputs (section Contacts description) by
applying the voltage of 7.0V ± 0.2V until the Terminal enters the bootloader mode. This function is used
only during an improper device flashing. An improper firmware is the firmware designed for terminals with
the other functional.
11.4 LED operation during reflashing.
Depending on the GSM modem and microcontroller units activation stages, the Terminal will go
through the following stages:
Yellow LED blinking,
times
GSM Modem activation stage
6 Procedure of GSM unit activation was successful.
5 GPRS service registration was successfully.
4 Establishing firmware update connection to the server was successful.
3 The Terminal switched to downloading mode.
2 Server connection is not lost, and the Terminal is in downloading mode.
1 First request sending was successful.
Blue LED blinking: each successfully received and recorded packet is accompanied by a blue LED light
change.
