2.2.5 Enable Verbose Mode
The SLN-VIZNAS-IOT kit supports debug message logging which provides important
inference performance information, for example, the time it took to detect a user. Serial
debug messages are disabled by default but can be enabled via a serial
command.
To enable serial debug output, type the serial command
“verbose 0”
,
“verbose 1”
,
“verbose 2”
, or
“verbose 3.”
Figure 18: "verbose 0"
Using the verbose command will enable logging of the debug information indicated in
the table below.
