Hi, I use ADuC and LPC2138 at work but this is a first attempt at using the STM32, with a prototyping board from Olimex. I am using an evaluation copy of the Real View MDK (V3.11) and a ULink as a JTAG programmer. When I try to upload to flash I get the message box "Error flash download failed - Target DLL has been cancelled" and the message "JTAG Communication Failure". The device is visible to the JTAG port, see a screenshot here:

Tis clearly some communication. What is the second JTAG device? The processor is a STM32F103RBT6 and this is what I have selected when I created my project. I have tried different speeds and changing the setting for whether the ULink drivers are externally or self powered.
Thanks in advance for any help,
Mark
