Error 'no schema file was found' when converting Tconf script to RTSC configuration script file

Sivakumar,
the space between --xp= and %XDCROOT% is the most likely cause of the problem. Please remove it and let me know if that doesn't fix the problem.

No. It requires space according to document Bios_Legacy_App_Note.pdf(SPRAAS7E). Anyway I tried without space, it gives error that can't locate the package 'ti.bios.conversion' along the path 'C:\Program Files\Texas Instruments\xdctools_3_20_08_88;C:\Program Files\Texas Instruments\xdctools_3_20_08_88\packages;'. Ensure that package path is set correctly.

The package 'ti.bios.conversion' is found in a SYS/BIOS installation. Therefore, you have to add a path to SYS/BIOS packages to the package path defined in --xp option.
Your command line should be:

xs --xp="C:/Program Files/Texas Instruments/bios_6_31_04_27/packages" ti.bios.conversion ...

No need to add XDCROOT to your package path because these packages are added automatically. The space between --xp and the path is needed if you don't have '='. You can't have both.

After I changing the command as you suggested and also added BIOS 5 path, I got RTSC configuration file. Now, I created new proejct (empty RTSC project) and used generated RTSC configuration file, compiled it and got following error,
