Jtag failure on Maple

I am trying to use the Keil jtag adapter on the Maple board.

I get a connect but the flash can not be programmed.

Anybody have experience with this configuration ??

One of the two normal JTAG headers is a 2x5 socket (the other is 2x10)
Maple r3 and r5 has a 2x4 header.

IIRC, the Maple designers joined the STM32F's NRST (Reset) signal to the JTAG JNTRST, rather than bring them out on separate JTAG header pins.

I have no idea what can be done with your JTAG, but I believe OpenOCD supported a workaround with an Olimex JTAG adapter, so it might be worth checking the internet or with Keil.
