Troubleshooting your DSTREAM-ST unit

Your DSTREAM-ST is built for robust performance, but problems can arise when incompatible
hardware is used with software, or when hardware is not configured or connected correctly, or from other
hardware-related issues.
If you are having issues with connections to your DSTREAM-ST unit, try the following:
Check list
Are you using the latest version of DS-5 Development Studio?
Are you using the latest firmware for DSTREAM-ST?
Are all the cables connected and seated properly in the correct
orientation?
Does the pin-out of the target's debug connector match the pin-out
of your DSTREAM-ST unit?
Have the target and DSTREAM-ST power cycled to ensure
normal operating conditions?
Has the DSTREAM-ST unit booted successfully?
Is the target system fully powered-up?
Does the target SoC have security features that must be disabled
or unlocked during connection?
Are there any switches or jumper links to set on the target?
Is the correct debug connector used on the target board?

4 Troubleshooting ARM
4.1 Troubleshooting your DSTREAM-ST unit

Table 4-1 Troubleshooting checklist

Download and install the latest version of DS-5 Development
Studio. New functionality, bug-fixes, and support for new
targets are provided with every release of DS-5.
Use the Debug Hardware Firmware Installer
to update the firmware for DSTREAM-ST.
Make sure all the cables are connected and seated properly.
Check that the stripe on the debug cable matches up with
pin-1 of the debug connector.
Check the DSTREAM-ST System and Interface Design
Reference guide for more information connection pin outs.
Power cycle the target and DSTREAM-ST.
Observe the progress of the boot sequence to confirm that
your DSTREAM-ST unit is booting properly. See
2.3 DSTREAM-ST unit boot sequence on page 2-20
information.
Check that the STATUS LED is glowing steady green.
If the STATUS LED flashes red, it signifies that a boot failure
has occurred. See 4.2 Restoring a DSTREAM-ST unit
on page 4-30 to see what to do in the event of a boot failure.
Check if the power up sequence specified by the target's
documentation is followed correctly.
Illuminated LEDs on the target do not necessarily mean that
the SoC and debug interface are powered. Check if there are
any buttons or switches on the target which must be operated
to enable the SoC and debug interface. Check your target's
documentation or support channels for more information.
Check the documentation of the SoC for details about security
features.
On some target boards, solder-links, jumper-links, or DIP
switches must be configured to enable debug. Check target
board documentation or support channels for more
information.
Some target boards use separate debug connectors for SoCs,
FPGAs, and processor core supervisors. Check if the correct
debug connector is used.
