Figure 3-1: Flash Memory Map

Use PSDsoft ExpressTM to modify the default settings for the flash memory, the DSM project must be modified and the flash must be reprogrammed using

FlashLINKTM. The default project files can be found in,

\…\VisualDSP\Blackfin\EZ-KITs\ADSP-21535\DSMConfigFiles. Analog Devices does not provide any support for setting up the DSM2150 with PSDsoft ExpressTM or programming it using FlashLINKTM. Email STMicroelectronics for technical assistance at apps.psd@st.com.

To program the flash with your boot code, you must first create a loader file from your DSP code. You will need to set up the loader in VisualDSP++ depending on how you will be booting the flash. The two possibilities are to boot the DSP in 16-bit external execution mode or in 8-bit boot mode. See section 4.3.3 for the boot mode settings.

Next, the loader file must be programmed into the flash. This can be done through the DSP using the VisualDSP++ Flash Programmer Utility (see section 3.8) or using by using the FlashLink programmer.

The DSM2150 can be reprogrammed using the FlashLINKTM JTAG programming cable available from STMicoreclectronics (www.st.com/psd) for approximately $59. FlashLINKTM plugs into any PC parallel port. The software development tool, PSDsoft Express, is required to modify the configuration of the DSM2150 and operate the FlashLINKTM cable. PSDsoft ExpressTM can be downloaded at no charge from at www.st.com/psd.
