Some problems of IVK Demo

I meet these problems recently:

1.Recently i reinstall the computer system and also reinstall the ISE software.And then this problem comes out:When i run the run_demo.bat, there are some messages appear in the CMD window:'impact' is not recognized as an internal or external command,operable program or batch file.'xmd' is not recognized as an internal or external command,operable program or batch file.I must miss something, can you tell me how to solve this?

2.I get "Detected Video Resolution 0x0 " message when i debug IVK_Camera_Buffer_Demo with SDK.These messages appears in the console:

FMC Module Validation

Board Information:

Manufacturer    = Avnet

Product Name    = FMC-IMAGEOV

Serial Number   = JBT341003811

Part Number     = AES-FMCIMAGEOV-G

SUCCESS : Detected FMC-IMAGEOV module!

Reset and Initialize the FMC devices ...

Camera 2 detected.

Detected Video Dimensions = 0 x 0

Unknown Video Resolution !

Defaulting Video Resolution to 720P

Clock generator set to 74.25 MHz.

---- Press Any Key To Continue ----

I have not changed board's setting or software of demo and then this problem suddenly comes out.And refer to the EDK Reference Design Tutorial.pdf, i probe the signals list in the pdf and i find the voltage of PG_C2M is 2.65V and only two signals are abnormal:

FMC-pin H31:FMC_DVO_HSYNC(freq i probe is 550.857Hz, which should be 47-48 KHz)

and FMC-pin H32:FMC_DVO_VSYNC(i can't probe,this signal is disordered).

What is causing this problem?

The run_demo.bat batch file requires the PATH environment variable to include paths to the Xilinx tools.

This may not be the case for the new version of the tools that you installed.

You can edit the run_demo.bat and explicitly include the path.

For example:

   echo Loading FPGA Design
   C:\Xilinx\12.2\ISE_DS\ISE\bin\nt\impact -batch download.cmd

   echo Loading Software Application
   C:\Xilinx\12.2\ISE_DS\EDK\bin\nt\xmd

Regarding the "Detected Video Resolution 0x0" issue, it looks like the I2C configuration of the OV9715 did not occur correctly.

Can you retry to load the pre-built bitstreams with the run_demo.bat batch file ?

Let me know if this works ...

Regards,

Mario.

Thank you,Mario.The first problem has been solved.Then i download the pre-built bitstreams with the run_demo.bat batch file,it still doesn't work.
