DSTREAM-HT Getting Started Guide
The number of lanes available is target dependent. If one lane is available,
the Channel LED illuminates green when the lane is ready for use. If more
than one lane is available, the lanes have to be bonded first. The Channel LED
illuminates green when the lanes are bonded and they are ready for use.
RX Data
Flashes green when the HSSTP probe is successfully receiving data.
Hard Error
Illuminates red to indicate that a high number of consecutive soft errors were detected. This
usually indicates that there are signal-integrity issues, or that there are bad connections with
the HSSTP signals.
Illuminates yellow to indicate that a hard error was detected, but is now resolved.
Soft Error
Illuminates red to indicate that badly encoded data is being received which is causing
disparity errors.
Illuminates yellow to indicate that disparity errors were detected, but are now resolved.
Frame Error
Illuminates red to indicate that the received frames do not match the expected format. For
example, Cyclic Redundancy Check (CRC) checking is enabled in the target device, but not in
the debug configuration.
Illuminates yellow to indicate that incorrect frames were received, but are now correct.
General Error
Illuminates red to indicate a miscellaneous error, such as CRC, End of Frame (EOF), or First in
First out (FIFO), overrun errors. Further diagnostic information is available through the Debug
Hardware log client, in Arm Development Studio:
debughw/tools2/dbghw_log_client
Illuminates yellow to indicate that a miscellaneous error was detected, but is now resolved.
GbD Link and GbD Data
These LEDs are currently reserved, and are not used by the HSSTP probe.
