Prerequisites: The board should be running Linux and connected to terminal console.

Note: For log level debug support, the restool version should be LSDK-2003-RC1 or above and MC version should be 10.20.0 or above.

To check restool version:

$ root@localhost:~# restool -v
restool LSDK-20.04

To check MC version:

root@localhost:~# restool -m
MC firmware version: 10.24.0

For debugging, use the ls-debug script available in the LSDK rootfs. There is no need to create the debug object.

ls-debug -h 

-h, –help	ls-debug help information
-ts, –timestamp=X	Enable/Disable timestamp printing, X is ON or OFF
-c, –console=X	Enable/Disable printing in UART console, X is ON or OFF
-l, –log=X	Enable/Disable printing in DDR log, X is ON or OF
-u, –uart=X	Set UART ID of the console, X = [0 – 4], 0 = OFF
-ll, –level=X	Set logging level, X = [0 – 5]0: Global1: Debug2: Info3: Warning4: Error5: Critical
-m, mem, –memory	Dump information about memory modules available
dpxy.z	Dump information about MC respective object

For example, to enable logging in console with log level INFO:

$ ls-debug --log=on --console=on --level=2              
dpdbg.0 created
DDR log printing ON
UART console printing ON
Log level set to 2
$ root@localhost:~# ls-debug --memory
Memory dumped information available in MC log/console
$ root@localhost:~# cat `find /dev/ -name "*mc_console"`
