C6711 DSK - Nikhil S. Parvatikar - Sep 27 10:17:00 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. -Nithin --- In , "sanjeev_aru" <sanjeev_aru@y...> wrote: > I am interested to collect audio samples, being sampled by the C6711 > DSK at 8 KHz, to a file in a PC.

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.
