Hello Team,

I was using parser script which is available at the location of SDK in parser scripts folder. when I used lvds_example_script.py I get some errors about the platform which is stated below.

"Traceback (most recent call last):
File "c:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\parser_scripts\lvds_example_script.py", line 90, in <module>
noise_buffer = parser_file(config_file_name, numFramesToBePrint, datacard_prefix)

if '68' not in CFG_PARAMS['platfrom'] and '64' not in CFG_PARAMS['platfrom']:
KeyError: 'platfrom'"

Can anyone here to solve my problem how I can remove the error.

Kind regards,
Fahad

    Hello Fahad.

    From looking at the script, there are some user changes that had to be made.  Could you please show what those changes were?  I am discussing this internally and will have a response by Monday or Tuesday.

    Sincerely,

    Santosh

    Hi santosh,

    I don't know what are those changes let me share the script file I only the config file where I changed Lvdsstreamcfg to -1 1 0 1 and I got the above the error. but on next time I changed the lvdsstreamcfg to -1 0 1 0 as shown below it runs and give me parser pass command but the output file is empty.

    Below are the output shown in the terminal.
