GalileoSky GLONASS/GPS v5.1 (223) User’s ManualGalileoSky Ltd Page 8111. BootloaderThe processor program (firmware) is a set of algorithms developed by GalileoSky Ltd specialists. Owing tothis program, the central processor receives the data from different system units, processes them logicallyand mathematically and takes decisions for control commands of controller units to be worked outdepending on the situation.Bootloader is a Terminal`s sub-programme allowing the main program part (hereinafter referred to asFirmware) 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 download1) 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 is reset in 15-20 sec;5) After resetting the Terminal will enter the bootloader mode, and the device should be defined as thesystem 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 download1) Connect the Terminal to the external power supply;2) APN settings must conform to the SIM-card inserted in the Terminal, otherwise, the device flashingwill 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 thelatest 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 modeAfter the device power supply is off, energize all analog-discrete inputs (section Contacts description) byapplying the voltage of 7.0V ± 0.2V until the Terminal enters the bootloader mode. This function is used onlyduring an improper device flashing. An improper firmware is the firmware designed for terminals with theother functional.11.4 LED operation during reflashingDepending on the GSM/3G-modem and microcontroller units activation stages, the Terminal will gothrough the following stages:Yellow LED blinking,times GSM/3G-modem activation stage6 Procedure of GSM/3G-unit activation was successful.5 GPRS/3G-service registration was successfully.4 F irmware update connection to the server.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. |
