Hardware prerequisites for using the bootloader 

To use the pre flashed bootloader the HW pins for 

UART

 and 

SWITCH_2

 need to be mapped according 

to 

Table 18

. This is the same pin mapping used by the u-connectXpress software.

IO_23 (P0.29) 

UART_TX

Table 18 Pin mapping used by boot loader 

The 

UART_CTS

 and 

UART_RTS

 (flow control signals) are optional, but u-blox recommend using flow 

control over the UART.
