Oflline memory analysis   
The Target board we are using does not have Ethernet OR JTAG. Only interface available is serial. 
Is it possible to get Offline memory analysis ? Like tracelogger? Then import the file to IDE for analysis

Request help

AW: Oflline memory analysis   
prerequisite is that you can store tracing data on your target and transfer this data later to your host pc.
If this is possible you can do all the analysis like System Profiling, Application Profiling or Memory Analysis.
-use tracelogger on your target to record kernel traces
-use any instrumented binary to record data usable for Application Profiling, contolled through env vars
-and some for Memory Profiling

in the IDE manual you'll not only find the "online" versions but also the hints 
you neede to use cmd line interface to record data and how to import them to IDE

Re: AW: Oflline memory analysis   
We are using QNX 6.3.2 version. Tried using 
LD_PRELOAD=/tmp/libmalloc_g.so MALLOC_TRACE=/tmp/log.memory
 MALLOC_CTHREAD=1 ./my_app

as in the 6.4.0 manual. Did not get any log in the tmp directory. 

Also tried with -pg option. Not sure why we did not get any log for application as well.
Am i missing something?

Request your help,

Thanks,
nkr

just to be sure: you're linking against shared libc?
you can check whether malloc_g is loaded? using env var DL_DEBUG=1

Re: AW: Oflline memory analysis   
What is the purpose of your analysis? Finding memory allocations? Memory leaks? or memory errors? You have to specify 
more options (env vars) depends on what are looking for

We wanted to analyze memory allocation, errors, heap for a program.

Thanks,

Re: AW: Oflline memory analysis   
In 6.4.0 and up it is something like this

LD_PRELOAD=librcheck.so MALLOC_TRACE=/tmp/output.rmat MALLOC_CKALLOC=1 
./your_app

It would create a file /tmp/output.rmat which can be imported to MAT 
tool in IDE.
Try simple case first:

main(){
   malloc(7);
}

Does it work?
