JTAG remapping pin PB4

Hi,

I am using an STM32F102C6 processor.  The design has an LED and resistor tied to 3.3V and Pin PB4.  I need to release this pin from JTAG and use it in OD mode to drive the LED.

So far I have:
Read all the documentation on pin remapping and selected the third JTAG option that remaps PB3 and PB4.
Checked all the other re-mappings for this part and concluded that they do not affect PB4 unless enabled.
Tried configuring the pin in both Out_OD and Af_OD modes with no results.
Tried everything on multiple boards.

Am I missing something?  It doesn't seem like this should be so difficult.

Thanks for your ideas.

Dave
