C5505 eZdsp USB Stick

I have a C5505 eZdsp USB Stick  and would like to 1) learn how to do developmental for it (home hobby stuff) and maybe do some development for it, but I have one MASSIVE road block right now, I can not figure out how to start the development for it under Linux (I do not have any windows or mac systems)  so do I have a paper weight or does any one know how to do development for it under Linux and what tools do/will I need.  And any documentation on how to upload any programs written for it to the device.

    Good news, bad news depending on your view.  The system has a card edge for JTag programming ( not for the faint of heart, can really brick things fast ) and a SMD EEPROM. 

    Refrenced from http://support.spectrumdigital.com/boards/usbstk5505/revb/

    So, depending how much information you can get on Linux JTag adapters/programming or how to ( in or out of system ) 512K-bit SPI EEPROM Flashing ( also not for the faint of heart for the same possible brick reason ) The Jtag adapter would be an option.  No clue where to start looking for the actual programming other than looking in to what is already Linux ready for de-bricking routers and associated JTag programmers.  I do have a home brew LPT ( buffered ) system and so far, the bricks I have tryed to unbrick turned out to be Cooked, not wrong firmware programming ( with one exception, but it was working ahead of the flashing so I knew it worked ).

    It's an option at least.

    Hope this points you in a direction to move it all forward,

    Thanks, if that is the only option that is the only option.  It just means the project for the dsp is going to take more time, as I still have to learn how to program a dsp also, and having to go around (as you put it) "not for the faint of heart" way, but if I was looking for easy I would not be a programmer, or using Slackware, so a bit of hard work is not something I am afraid of.
