That is one solution, although there is another one, even cheaper: the JTAG interface on the EzKit, which you access to via USB, enables you to program the onboard Flash memory, with whatever .ldr file you have developed. You first load a flash programming driver, which is nothing but a .dxe (DSP executable file) that you load (via the USB-JTAG interface) into the DSP and enables you to write to the flash memory from the DSP! I think the menu options in VisualDSP++ are Tools -> Flash Programming. Those PDS devices are more than a simple flash memory (http://www.st.com/stonline/products/families/memories/psm/index.htm). They integrate a PLD and often times (depending on the model) also a secondary flash memory. ST provides the FlashLINK JTAG parallel port programmer, which added to the PSD SoftExpress software enables you to modify the PLD equations, besides reprogrammng the flash. For simple usage of the flash memory as non-volatile storage for your DSP programs, you don't need the FlashLINK nor PSD SoftExpress tools, the VisualDSP++ Flash Programming Driver will suffice. I wouldn't recommend you to change the PLD equations unless you REALLY know what you are doing, because you might misconfigure some settings of the kit. > 3.

I've used ucLinux, but on the STAMP board, I've not used it yet on the EzKit. > Thanks again for your help, and sorry if I asked so > often if the JTAG Don't worry, I like to share the few things I know about ADI DSPs, and make it easy to others to start using them. > emulator is absolutely necessary, but it is a bit to > expensive for my > university group. Yes, it IS! Jaime Andr Aranguren Cardona __________________________________________________ |
