Hi,
Is your target configuration set properly?
[quote]The value is '-180' (0xffffff4c).
The title is 'SC_ERR_CTL_NO_TRG_POWER'.
The explanation is:
The controller has detected a target power loss.
The user must turn-on or connect the power supply for the target.[/quote]
Indicates that the board has no power applied to it. I would check the power to the board (I managed to make it work with both the 5V and the USB power) or the JTAG line TVRef. For details on JTAG pinout check section Emulation Header signal definitions of the page below:
