Windows PC
TFTPS server, for example Tftpd32 or Tftpd64 by Ph. Jounin (http://tftpd32.jounin.net)
Telnet software, for example PuTTY by Simon Tatham (http://www.chiark.greenend.org.uk/~sgtatham/putty/)
Simple network switch
2 Ethernet cables
Special USB-Serial cable with JTAG connector
Flowire unit
Flowire power supply

You need an RS232 cable with 3,3V TTL level. For example: http://au.element14.com/ftdi/ttl-232r-3v3/connector-type-a/dp/1329311
Create an adapter cable to connect to the debug connector on Flowire:

Flowire cable

On the Flowire, you must connect to these pins:
- 7: GND
- 8: UART1_TX – Connect this to Rx on the serial cable
- 16: UART1_RX – Connect this to Tx on the serial cable

Flowire pinning

PC Setup

Connect the USB-Serial cable
Check the "Windows Device Manager" to see which serial port it chooses. It will be listed under “Ports (COM % LPT)” as USB Serial COM port #x, where x represents the COM port number. Double click it and change the port settings from 9600 baud to 115200 baud.
