Debugging¶
First review the FAQ for commonly encountered issues across the Kria SOM applications.
This section list some debugging tips for the application¶
Make sure you use:
sudo xmutil loadapp kv260-nlp-smartvisionto load the firmware properly; otherwise, many drivers including the MIPI will not load, so there will be many errors when you run the application.
This section list some debugging tips for platform peripherals¶
Monitor¶
Review the Debug Displays for debugging the monitor.
Audio¶

Determine the Enumeration for Audio Card¶
cat /proc/asound/cards
2 [xlnxi2ssndcard0]: xlnx-i2s-snd-ca - xlnx-i2s-snd-card-0
xlnx-i2s-snd-card-0
In the above example, the enumeration of audio card is 2.
Determine Capture and Playback Device Number¶
cat /proc/asound/devices
80: [ 2- 0]: digital audio playback
89: [ 2- 1]: digital audio capture
In the above example [2- X]: 2- is card, X is the device.
Sample Record and Playback¶
dnf install alsa-utils.aarch64Ensure an active source is connected at the Pmod LINE IN.

`ls /dev/media*`Lists all media enumerations
media-ctl -d /dev/mediaX -p
where X in media is the enumerated value. The above command will print the Device topology and help you identify the media device.
Here is an example for capture path of ‘ar1335 sensor’.
media-ctl -d /dev/media0 -p
