programming problem after Remapping PB3 & PB4

Posted on August 07, 2013 at 10:35

Hello,

I equipped the Header of the STM32F100RB-VL Dicovery Board with some LEDs. But then I recognised that PB3 and PB4 are not working, because they have to be remapped. Since this remapping I`m not able to flash the Discovery Board again. I read the notice in application note ''

Once the JTAG I/Os are disabled, connection with the host debugger is lost and cannot be re-established as long as the JTAG I/Os remain disabled''

I don`t know how to fix this. I`m working with Keil µVision.

Any Ideas?

Thank`s in advance.
