Blackfin and SHARC DSPs generally use external flash memory for bootloading and other data storage. This flash can be preprogrammed before soldering onto the board, programmed with a bed of nails tester, or programmed via JTAG using an ADI ICE and Visual DSP++. None of these methods are ideal for production targets.
The dspFlash™ SHARC & Blackfin Programmer is a production programmer from Danville Signal Processing that
supports Blackfins and third generation SHARC DSPs. Thousands of DSP - flash memory configurations are supported, all you need is a standard ADI JTAG connection on your target.
How it works .......
The dspFlash programmer is connected via USB to a PC running Windows 2000, XP, Vista or Windows 7. Your target is connected via an inexpensive removable ribbon cable to a standard ADI JTAG connector.
The dspFlash programmer works in concert with the dspFlash Windows software program. You specify the target DSP, flash device, chip select, file format and data files.
Files are uploaded to each dspFlash programmer's internal SDRAM. Since the data now resides in the dspFlash programmer, it doesn't need to be downloaded each time when programming multiple devices. You are now ready to start programming.
You connect the programming cable to a powered target. The programmer automatically configures its I/O to the correct voltage of the target. Press "Write File" and the DSP writes its own flash. It doesn't rely on bit-banging via boundary scan. This would be possible but very slow. The programmer is fast, much faster than even an ADI HP-USB ICE and the VisualDSP++ flash programming utility. You can also write supplemental information. For example, you might want to add a serial number or calibration values.
The dspFlash Deluxe can also load and execute DSP programs independently of flash programming.
Take a Test Drive in Demo Mode:
You can download the dspFlash Windows Application zip file and take it for a test drive in demo mode.
