As I said above.I meet the questions when I set the CCS3.3 to F28027 Device Simulator and F28335 Device Simulator,however not the F2812 Device Simulator.
after I execute the command checkEnvSetup('ccs','F28027','check'),it replys like these:

it seems that there are some question with the DSP2802x_INSTALLDIR="" and FLASH_2802X_API_INSTALLDIR="",but I don't konw how to slove it .
And I have seen somebody have the question with 2802x_INSTALLDIR="" get the answer like this
linking the mathlab variable "C280x_INSTALLDIR" to the ControlSuite_Dir\device_support\f2802x\v129,
which in http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/147339/538647.aspx#538647.
Wait for you help.Thankyou.
