Rama,
The project was probably designed for Windows, as the error message points to a tiobj2bin.bat. If you right click on the project, then select Properties --> Build --> tab Steps. In the box Post-build steps check the command line there. It is possibly something along the lines of:
"${CCS_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin.bat" "../../../../../../../binary/armv7a/cgt_ccs/am335x/evmskAM335x/uart/${ConfigName}/${ProjName}.out" "../../../../../../../binary/armv7a/cgt_ccs/am335x/evmskAM335x/uart/${ConfigName}/${ProjName}.bin" "${CG_TOOL_ROOT}/bin/armofd.exe" "${CG_TOOL_ROOT}/bin/armhex.exe" "${CCS_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin.exe" & "../../../../../../../tools/ti_image/tiimage.exe" "0x80000000" "NONE" "../../../../../../../binary/armv7a/cgt_ccs/am335x/evmskAM335x/uart/${ConfigName}/${ProjName}.bin" "../../../../../../../binary/armv7a/cgt_ccs/am335x/evmskAM335x/uart/${ConfigName}/${ProjName}_ti.bin"
Removing the .bat extension should work fine.
Regards,
