Board Specific Issues
1.1 Do I need a JTAG Emulator for Debug of the eZdsp boards?
JTAG emulation is required for debug support using Code Composer Studio.
JTAG emulation also allows flash programming of the C2000 devices.
eZdsp boards from Spectrum Digital have on-board JTAG Emulation. The on-board JTAG Emulation allows direct connection between the computer and eZdsp board via parallel port or USB, depending on the eZdsp board being used.
Evaluation Modules(EVMs) do not have on-board JTAG emulation and will an external JTAG Emulator to connect via the standard 14-pin JTAG header. Spectrum Digital develops, manufactures, and sells JTAG emulator. Details about our JTAG emulators can be found at:

1.2 What is the Difference between and Evaluation Module and eZdsp board?
Evaluation modules(EVMs) offer greater peripheral support on board. The EVM may have a serial port, CAN interface,LEDs, RAM, etc... that the eZdsp boards do not have. Althought the eZdsp boards are limited in the on-board peripherals, both boards have expansion headers that allow the user to interface their own logic to the DSP.
The eZdsp boards have one feature that the EVM board does not. The eZdsp has on-board JTAG Emulation. The on-board emulator allows the user to perform JTAG Debug and flash programming without the need of an external JTAG Emulator. The on-board emulation interfaces with the PC via parallel port or USB interface.
1.3 Do Spectrum Digital Boards Support Flash Programming?
Spectrum Digital Evaluation Modules(EVMs) and eZdsp boards for the C2000 family of DSPs allow flash programming. The SDFlash utility or the flash programming plug-in for Code Composer Studio allows flash programming of the C2000 DSP's on-chip flash via JTAG. The eZdsp boards have on-board JTAG emulation which interfaces to the PC via parallel port or USB. The EVM boards require an external JTAG emulator for Debug and flash programming capability.
The SDFlash utility can be downloaded from the Spectrum Digital website. Please go to "" for details about the SDFlash. The plug-in for Code Composer Studio can be downloaded from the Texas Instruments website,

1.4 Will Spectrum Digtal boards run stand alone or execute out of Flash?
The eZdsps and EVM boards have jumpers on board to allow the chip to be put into Microcontroller or Microprocessor mode. This allows the user to develop out of RAM or when ready, program the flash and allow the part to execute out of Flash.
