    Very simply put, you first have to be able to access the Flash, e.g. run a Flash format test. If that works, you simply modify the exProductionBurn target

      exProductionBurn target build from JTAG to PCI and it should
      just work.

      How can I download my application program to nor flash using pci bus
      without using jtag?
      Hardware reference information as follows:
      1¡¢Main processor is PNX1700 series
      2¡¢EEPROM is 24LC256 on IIc bus
      3¡¢Using nor flash ,flash size is 4M*8bit ,connected to dsp pci bus
      4¡¢We are using ndk5.5 and tcs5.01
      My problem is as follows:
      1¡¢My circuit board is inserted on computer by pci bus ,the program of
      eeprom is ok,now we need download our application program to flash
      using pci ,not using jtag . What should I do?
      2¡¢In ndk documents,refered to :
      In NDK4.3
      Build memory image of the application software
      build_exe kernel\comps\tmBffs\tst\exLED
      This will create exLED.mi
      Build uBTM without avbsl and in read only to minimize
      set _TMDIVERSITY=_sp_pnx1500_noavbsl_bffsro_BTM
      build_exe boards\comps\tmbtNref
      This will create tmMicroBtm.mi
      This will also create several boot script, .EEPROM files
      Build NDK Boot Loader
      build_exe kernel\apps\exNBL
      This will create exNBL.mi
      Build BFFS format utility
      Above 3 files are converted to header files if flash writing is
      via JTAG
      build_exe kernel\apps\exBffsFormat
      By running this, flash will be erased, compress, and write all
      to flash
      Does this program can using pci load program to flash without using
      jtag?
      4¡¢If ndk4.3 can resolve my problem , please send your ndk4.3 to my
      emai,my email:wangshh03@...
      Thanks!!!
