There's a tutorial, and several demo apps there also.

You will need to load in the Keil Assembler output Intel Hex file.


Reset the FX2's 8051 like this:
...
        ResetUSB8051(TRUE);


bool CUSBFirm::ResetUSB8051(UCHAR reset)
CCyControlEndPoint  *ctrlEpt = m_pFX2Device->ControlEndPt;

 ctrlEpt->Target    = TGT_DEVICE;
 ctrlEpt->ReqType   = REQ_VENDOR;
 ctrlEpt->Direction = DIR_TO_DEVICE;
 ctrlEpt->ReqCode   = 0xA0;  //ANCHOR_DOWNLOAD
 ctrlEpt->Value     = 0xE600;  //7F92?
 ctrlEpt->Index     = 0;

 UCHAR ucStop = reset;
 LONG lBytesToSend = 1;
 if(false == ctrlEpt->Write(&ucStop,lBytesToSend))
.....

Then.. Parse the intel hex file and send the address/data down to the FX2 a 
line at a time and lift the 8051 Reset like this

ResetUSB8051(FALSE);

That's all I am gonna give you on the Windows side.. gotta do some of this 
yourself!

The docs for doing this are on the Cypress Website..

Hi All, 
I am using EZ USB FX2 dev kit. I am just new to this all and need to
program 8051 through a firmware program. I am working in windows
environment. I need help about how to start and specially in finding some
sample "firmware Program" which can be compiled through keil.

Thanks in advance
