Using ST Link on Discovery board as standalone ST Link

I have

 (board only), and I need

a 

JTAG debugger to program it.  Is it possible to use my F1 discovery as a JTAG debugger for the purpose of programming?  I am totally new to STM32, but I am excited to learn.  

Thanks, 

Dave

You should be able use a VL-Discovery to program it via the SWD connections. You'd need to remove the internal jumpered connections, and then wire up the SWDIO (JTMS), SWCLK (JTCK), and GND to the associated pins on the 20-pin JTAG header.

In an ideal world you'd probably want NRST too.

The SWD header does not provide for full JTAG functionality.

That is exactly how I am using my STM32F0DISCOVERY as clive describes it. You only need two wires plus ground.
