Introduction and Purpose
The purpose of this guide is to provide list of reason of DSP Failure and how to troubleshoot the same.
...
DSP Status
DSP Information
DSP Status
DSP status show the status of DSP on VEGA i.e. whether DSP is Active state or DSP state is FAILED as shown below:
...
DSP Information
DSP Information will provide all the necessary information with respect to DSP channels status etc if active else provide the reason for DSP Failure.
...
DSP information when DSP Status is FAILED as shown below:
...
DSP Failure Reason
There can be number of reason of DSP Failure as stated below:
Hardware Failure (HWFAIL)
Unavailable (UNAVAIL)
DSP Image download failure (SWFAIL)
DSP stopped responding (SWFAIL)
DSP disabled (UNAVAIL)
DSP fatal runtime error (SWFAIL)

NOTE: UNAVAIL stands for Unavailable, HWFAIL stands for Hardware Failure and SWFAIL stands for Software Failure |
Troubleshoot DSP Failure
As explained DSP Failure may be due to multiple reason. Now if order to troubleshoot DSP failure there are two steps:
Step 1) Check if DSP Failure is due to DSP upgrade Required?
If DSP is Failed due to DSP Upgrade then in such case DSP Upgrade button with a help button will appear on to VEGA GUI in front of DSP Status as shown below:
...
Now, Check if the output of above command has different "VEGA Supported DSP Firmware Version" and "VEGA Octasic Chip Version" then we are sure the the cause of DSP Failure is mismatch of DSP version
and DSP upgrade is required as shown below:
...

NOTE: The same command can be executed on VEGA CLI in order to get the same output. |
Step 2) Take appropriate action
Now if the DSP Failure is due to mismatch of DSP version i.e. DSP upgrade is required then please follow the steps as stated here: DSP Upgrade Procedure
It might be possible that the DSP Upgrade itself get failed.
TroubleShoot DSP Upgrade Procedure Failure
The possible reason of DSP Upgrade Failures are:
Invalid DSP Firmware uploaded
Checksum mismatch
Improper Space present on VEGA in order to upload DSP
Invalid DSP Firmware / CheckSum Mismatch
In case of Invalid DSP Firmware Uploaded and Checksum mismatch the UI should display proper information on to VEGA screen this means that that either the DSP Firmware has been uploaded on to VEGA or the DSP Firmware is not properly copied on to VEGA.
DSP Failure due to no space available on to VEGA
It is possible that the DSP Upgrade Procedure will get Failed with no proper information present on to the VEGA GUI. In such case please follow below steps:
