Reset button 

The RST button on the front side resets the u-blox F10 receiver. 

 

4.5

 

Safe boot button 

This is used to set the unit in safe boot mode. In this mode the receiver executes only minimal 
functionality, such as updating new firmware into the flash memory. To set the receiver in safe boot 
mode: 

1.

 

Press the BOOT button and keep holding it down. 

2.

 

Press the RST button. 

3.

 

Release the RST button. 

4.

 

Release the BOOT button. 

5.

 

If the UART interface is used, a training sequence must be sent to the receiver. 

The training sequence is a transmission of 0x55 0x55 at a baud rate of 9600 baud. Wait for at least 
100 milliseconds before the interface is ready to accept commands. 

 

4.6

 

LED 

On the front panel of the EVK unit, a single blue LED  shows the time  pulse signal. The default 
configuration has the following functionality: 

LED 

Description 

Solid blue

 

The device is powered on with no GNSS fix. 

Flashing blue

 

The LED flashes one pulse per second during a GNSS fix. 

Table 5 LED description 

The time pulse signal is configurable. For details, see the Interface description [2]. 

 

4.7

 

Flash memory 

EVK-F10T has an 8-Mbit SPI 

ash built-in in the NEO-F10T receiver. It can be used to store the current 

configuration

 permanently. 

 

4.8

 

External interrupt 

On the EVK-F10T, the external interrupt (EXTINT) signal is available on the 14-pin connector. The 
EXTINT signal can be used for time mark and time aiding features of the receiver, as well as for waking 
up the receiver from software standby power save mode.  See section 14-pin connector  for more 
information.
