DSTREAM-ST Getting Started Guide
Check List
In the Arm Development Studio debug configuration for the target,
does the Target Connection option match the debug unit?
Does the platform configuration settings for your target specify the
correct debug interface mode?
Is an SWD connection being attempted with hardware which only
supports JTAG?
Are trace capture options correctly set?
Are core trace options correctly set with the appropriate cores
enabled?
Is the TRACING LED lit but the DATA LED unlit?

Things to check
Check if you have selected the DSTREAM-ST unit as the
Target Connection option in the Connection tab of the debug
configuration for your target.
Check if the LVDS Debug Interface mode is set correctly in the
platform configuration settings for your target.
Check and correct the connection setting. Even if the SoC supports
SWD, there might be buffers on the target board which prevent
bi-directional data on the TMS signal. Check and correct the
connection setting.
Check that the trace capture settings used for the debug
configuration are set correctly.
Check that the core trace options used for the debug configuration
are set correctly.
This indicates failure to synchronize with the trace data stream.
Check if the target SoC's TPIU or I/O pins are configured correctly.
