C6711 DSK

Started by Nikhil S. Parvatikar September 27, 2001
Hi !!!
 
I needed the following help.........
I have a DSK C6711 board with me............
I am trying to port my code on the DSP..
I am new to using the DSK...
The following are the problems.....
 
I have a code which compiles & linkes without any problem........
i looked at the Map file for making changes in the Command file......
since my code doesnot fit completely in the Internal RAM ( 64 KB )
i have put certain sections in the External memory ( starting at 0x80000000 )
the code loads on the DSP without any problems ........ ( some times if i change the location i have a problem )
now when i want to debug i have a problem the it debugs only till some stage & then i get this dis assembly window......
I think it is a Memory problem............ kindly sugget....
 
i think my code is falling in the restricted areas of the memory...........hence i am not able to run after loading....
 
My questions are as follows.........
 
1) Is a linker command file a MUST to port the code on the target coz i have loaded a few Tutorial programs that run with or
without the command file.........and it still works
 
2) where can i get the information on the linker command files........
Can i run the code completely on the External RAM ( i think it should be possible kindly clarify......)
or should some part of the code be on the Internal RAM.....
 
3) Where can i get the complete Memory map of C6711 DSK i have looked at GEL_MAPADD( ) of C6211;
in the CCS 2.0.
 
 
I am sure ur that ur suggestions will be of great help.......
 
bye

I am interested to collect audio samples, being sampled by the C6711
DSK at 8 KHz, to a file in a PC. I used LOG_printf and developed a
DSP/BIOS program. It does job of collection the samples in a file but
misses entries randomly.

Is there any solution to this problem?

The LOG_printf, even if data is less, one variable in 20 ms, doesn't
seem to work reliably, without missing data. Same was tried using
XDS560 also to avoid data rate problem but problem exists.

Any suggestion/example code/pdf etc

thanks



I am no expert in this but I guess it might have to do with ur size
of log buffer ...u might want to use the STS object to check how
many times log-printf was executed and how many samples captured in
that period.

Probably other experts in the group may be able to give a better
solution.

Sanjeev_aru,
 
From the CCS help file-
 Disable types of logging that are not relevant to the analysis you are performing in the RTA Control Panel.
 In the configuration file, increase the buflen of the log so that a longer sequence of events can be stored.
 Increase the polling rate so that fewer events will occur and be overwritten in the log by new events before the target has a chance to gather the log information.
 
I have used #2 and/or #3 to solve similar problems.
