Help with programming STM32F103RCT6 board.

makiyoung

I have bought  this Cortex M3 board. Now I want to program it through jtag.

So I bought this wire. By using the USB to serial interface of my linux machine, I want to program the board.

I went to read the data sheet of board here[1]. In section 2.3.29, it is written:

The ARM SWJ-DP Interface is embedded, and is a combined JTAG and serial wire debug port that enables either a serial wire debug or a JTAG probe to be connected to the target. The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.

So if my reading is correct, I will use the SWDIO and SWDCLK ports to try to tinker with the board. Or am I missing something grave here?

    Are you asking if you can use a USB to serial adapter to interface with the SWD JTAG port on your board?  If so, the answer is NO. 

    The RS-232 style serial communications interface provided by a USB to Serial adapter has dedicated TX and RX pins.  The JTAG serial interface uses a single pin, SWDIO, to both send and receive data.
