Without result so far, I have made several attempts to share a single SWD-bus to debug two LPC11Cxx MCUs.

Debugging in LPCXpresso works fine with a single MCU on the PCB, however when the second MCU is added the I get the following error.

[color=#f00]Target error from Register access: Nn(05). ACK Fault
terminating on communication loss: Pipe has been closed by GDB.[/color]

If possible, I would like to know how to create a shared SWD-bus as discribed in the link below?
