ADSP-21065L hangs | Analog Devices DSPs

Technical discussions related to Analog Devices DSPs (including Blackfin, TigerSHARC, SHARC and ADSP-21xx DSPs).

Hi, I am trying to get a talkthrough program working on the DSP-21065L EZ-Kit Lite, using VisualDSP++ 3.5.3.0. My code is from the BP project, located under C:/VisualDSP++3. 5for32-Bit/21k/EZ-Kits/21065L/Demos/. I had to modify the following two lines in the LDF-file slightly, from seg_rth { TYPE(PM RAM) START(0x00008000) END(0x0000808e) WIDTH(48) } seg_init { TYPE(PM RAM) START(0x0000c000) END(0x0000c007) WIDTH(48) } to seg_rth { TYPE(PM RAM) START(0x00008000) END(0x000080FF) WIDTH(48) } seg_init { TYPE(PM RAM) START(0x0000c000) END(0x0000c007) WIDTH(48) } in order to get the program to compile. After that I was able to compile, download and start the program, but when I try to stop it I get the following error message: Target #256: Error #905 Communications TimeOut Anybody else that have seen this problem with the DSP-21065L EZ-Kit Lite?

>Anybody else that have seen this problem with the DSP-21065L EZ-Kit >Lite? I haven't seen it as I work with the 218x processors. But I can guess what you've done. It looks as if you're overwriting the monitor program (the small routine in the DSP that communicates with VisualDSP++ software) with some part of your own program. (I'm guessing the monitor lives at locations 808e to 80ff.) You'll need to alter your talkthrough program code so that it doesn't try to load itself into this area of memory. Then it will compile happily without the changes made to the LDF file and should run OK. Good luck, Steve Conner OptoSci Ltd.
