5 Troubleshooting the Decoder
20 LPDDR5 Decoder User’s Guide
Common Problems and Recommended Solutions
Problem Cause Recommended Solution
Logic analyzer "hangs up"
just after capturing a trace
and the following status
message is displayed at the
bottom of the screen. This indicates that the decoder is busy
decoding the captured data. If the "Processing" message doesn't go away after
a minute or two, it is possible that the decoder is
searching through an enormous number of idle
states in between "meaningful" states.
In such a situation, you can use the Cancel button
to stop the decoder.
No trace list display The trigger specification may be incorrect
for the data you want to capture, or the
trace memory may be only partially filled. • Check your trigger sequence to ensure that it
will capture the events of interest.
• Try stopping the analyzer; if the trace list is
partially filled, this should display the contents
of trace memory.
Logic analyzer won't power
up If logic analyzer power is cycled when the
logic analyzer is connected to a device
under test that remains powered up, the
logic analyzer may not be able to power up.
Some logic analyzers are inhibited from
powering up when they are connected to a
device under test that is already powered
up. Remove power from the device under test, then
disconnect all logic analyzer cabling. This will
allow the logic analyzer to power up. Reconnect
logic analyzer cabling after power up.
