Bootloader
The processor program (firmware) is a set of algorithms developed by GalileoSky Ltd specialists. Owing to
this program the central processor receives data from different system units, processes them logically and
mathematically and takes decisions for controller units control commands to be worked out depending on
the situation.
Bootloader is a subroutine allowing the main program part to be 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.
USB channel download
1)
Attach the device to external power supply;
2)
Connect the USB cable;
3)
Launch Configurator and open the Command mode tab;
4)
Type in upgrade 0 after which the device will be reset in 15-20 sec;
5)
After resetting the device will enter the bootloader mode with the system storage device (flash
memory) to be identified;
6)
Download the right
firmware
version and rename it as firmware.bin;
7)
Copy the downloaded version (firmware.bin) to the flash memory;
8)
With flashing completed the device will be reset and enter the operating mode in 15 seconds.
GPRS channel download
1)
Attach the device to external power supply;
2)
APN settings must conform with the SIM card, otherwise the device flashing will not happen and it
will return to the operating mode;
Using any available channel (SMS, GPRS, USB) give the following command: UPGRADE firmware#,
where firmware# is the necessary
firmware
version. UPGRADE 0 initiates downloading the latest
firmware;
3) You may see 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 is completed and the terminal automatically turns into operation mode.
Using analog inputs to enter bootloader mode
After the device power supply is off apply the voltage of 7.0V ± 0.2V to all discrete-analog inputs (see
Contacts description) until the device enters the bootloader mode. This function is used only during an
improper device flashing. By improper we mean flashing intended for devices with a different set of
functions.
