Blackfin EZ-KIT Lite

Started by Leon Heller July 17, 2003
I received my Blackfin EZ-KIT Lite (on special offer last month) yesterday,
and got it working this afternoon. I had problems getting WinME to start
properly after installing the software, and eventually tried disabling the
Norton virus software. This seemed to do the trick.

I was thinking of creating a Yahoo group for users, but found that a
Blackfin Interest Group already existed, so I joined it. It isn't very
active (only 15 members and six messages), but now that there are lots of
kits out there, more people might join.

Leon, try the ADSP Yahoo group - we've had more on the Blackfin than six messages :) http://groups.yahoo.com/group/adsp/ Regards, Andor

I'd forgotten about that group. I'm a member of that as well. Leon -- Leon Heller, G1HSM leon_heller@hotmail.com http://www.geocities.com/leon_heller

For the lurkers: http://groups.yahoo.com/group/blackfinlist http://groups.yahoo.com/group/ad_blackfin http://groups.yahoo.com/group/adsp There's also a nice Blackfin blog here: http://www.dsperado.com/chiclet/ -- Kenneth Porter http://www.sewingwitch.com/ken/

I received the BF533 version a few days ago. This is very much a learning tool for me as I've not done hands-on programming of one of these before - ever. I'm trying to figure it out and have a couple of questions someone may be able to answer directly: The documentation says that user memory is limited to 20kB. That seems quite restrictive in relation to the memory that's available. How should I be interpreting this? Expecting to deal with it? They offer an emulator for around $5K. So, what is it that I have in this $99 kit with Visual DSP++? What is it I don't have / can't do with it? Just a little context would help me understand. Thanks, Fred

You got also a kind of JTAG emulator... The USB interface on this kit goes to the JTAG pins, so it's like having the emulator. The difference might be that with an emulator (5K) you can interface to _any_ ADI DSP based system, as long as it incorporates a JATG interface, not limited to the kit on hand. It would be certainly faster, robust, DSP platform-independent, etc... Another difference is that the EzKit version of VDSP++ will only work with the kit actually connected, kind of dongle. So, you won't be able to use your SW for developing for other DSP chips. Those significative differeces come to my mind at this moment. There are some others, no doubt. Anyway, I hope this gives you some enlightment. Regards, JaaC

Al, I noticed that as well. It says 20kB. How do I assess that with respect to what the chip is capable of and what sort of capability one might want to program? It sounds small compared to what memory's available. I'm just looking for a sense of it. Thanks, Fred

I've written a lot of DSP applications with less than 20k memory (not Blackfin). Its my understanding that this does not mean you can't access the remaining memory. It means program size is restricted. I may be the wrong person to ask since we have Full Visyual DSP licenses without the restrictions. -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- Purveyors of Fine DSP Hardware and other Cool Stuff Available at http://www.danvillesignal.com

Al, Oh, OK. Well, that's an encouraging starting point at least. I'd be both disappointed and surprised to find that the software limitations made the kit not very useful. All to do now is to proceed! Fred
