tms320c6701 and DSP bios - faysal basci - Feb 28 20:02:00 2002

I'm using c6701 based TI DSP board with JTAG and CCS ver2.0. I'm
implementing FX-LMS algortihm; to do real time debugging I'm trying to use
DSP bios, however, I could not make my program run. I compiles and builds
with a warning saying ".args not found" . When I load it, the program does
not start. I could not figure out why it issues this warning... The same
code works fine without dsp bios. Is there anyone who can suggest something?
Or someone that could suggest another way of debugging... Profiling or
putting watches does not make any sense in this case, because halting
processor ruins the algorithm. I have to get feedback from the processor in
real time. Any help is greatly appriciated.

Thanks in advance.

For step-by-step guidance on using BIOS in an existing application, in your case for real time printf, etc, check out the appnote on http://dspvillage.ti.com search for BIOS by Degrees to get access to the pdf: "DSP/BIOS by Degrees: Using DSP/BIOS in an existing application (SPRA783A)" This will give guidance on the use of the DSP/BIOS configuration file and the generated source and linker command files as well as the structure of the main. There is also information in the CCS tutorial which may assist (select Help->Tutorial , then Using DSP/BIOS) Regards, Thom -----Original Message----- From: faysal basci [mailto:] Sent: Thursday, February 28, 2002 12:03 PM To: Subject: [c6x] tms320c6701 and DSP bios I'm using c6701 based TI DSP board with JTAG and CCS ver2.0.
