hi! ,All!
Thanx for the help.
the problem was actually with LINKER FILE. the file "lnk.cmd" was not
suitable for the application as i removed it , the code worked fine, at least
for Reading. Mr. Tahir has suggested same. but i don't know how to modify
& how to decide what to modify in Linked file. if any body have any Doc or
suggetions pls help.
Thanx & Regards
swapnali

Hi,
It is likely your DSP code is deeply crashed
and CCS cannot
talk anymore with the DSP.
When using TI DSP and CCS, file access is done
through the JTAG
interface using a communication
library.
If your DSP get crashed then JTAG link may
get broken and things
similar to what you are listing occurs. If you are sure that the hardware
platform is stable, then it looks like code is
damaged
by a fool pointer or something like
that.
I suggest to go for the old and legacy way :
comment code to find out
what could make it crashing.
regards,
jean-michel.

HI! all
can any 1 help for Reading & Writting a *.bmp file to & from the
hard-disk, the code is perfectly working with VC++ editor, while running
same code on CCS giving Message as follows.

i think i am missing the CCS specific,functions, i am using the Fwrite

_____________________________________ About this discussion group:
I am pretty worried because it is the first time I program a realtime
application and it is pretty difficult at my level.
Here are the features of this application (C6713 because it is the only
one can be used in space model) :
McBSP communication with a FPGA (10 MHz for the clock)
UART communication with a computer (115 200 bauds)
Manage 10 ADC and 10 DAC to do a locking of the system based
on 10
different parameters...
And I am really worried about the end performances of the system...
See why I am looking for tips (and because my company does not want to
pay me a formation :'()
Bye ! Olivier

Subject: [c6x] Tips for beginner in real time
Hi !
I am a beginner in real time coding and I wander if someone can give me
some advices to program a DSP like the C6713 ?
I think there is several rules to follow but I do not know them.
I think the most important rule is don't worry about rules too
much. Just
start doing the work. There will be lessons learned, but that is half the
fun.
There are examples that come with the 6713 DSK. That is a good place to
start, i.e. get them working.
Regards,
Robert

The only rule to worry about in realtime programming is to meet the realtime
deadlines.
To begin with I would look at the comp.realtime archives and Amazon.com for
some reference texts. Once you know what the latency is and the difference
between soft and hard realtime, you would feel more confident.
Regards,
Andrew

Hi !

some advices to program a DSP like the C6713 ?
I think there is several rules to follow but I do not know them.
For example, it is best to use switch(case) rather than if... else if
... else if... else or the opposite ?
