helloWorld_evmc6670 release configuration?

David Halls

Hi,

I tried to amalgamate with some other code, and all was well until I went to use the Release configuration, at which point the UDP part of the code stopped working.

I returned to the helloWorld_evmc6670 example and saw that it doesn't have a Release configuration? I created one, setting the optimization level to 3 and optimize for code size to 0. I turned off the debugging model in Debug options.

The example now does not work, and when I run the winapps/helloworld.exe it times out "timed out waiting for reply".

How can I get this to run using a Release configuration??

Thanks!

Dear David,
Able to make it work again if you modify the optimization level ?

Thanks Titus,

Yes, I have found that if I turn off optimization then it works.

The behaviour with optimization is strange. Putting lines of debug in, it seems that with optimization it sends the reply to itself, rather than back to the PC client, or something...

With optimization off, it still crashes out after the timeout period, I think. I am still debugging (fiddling).

Is there a clear reason why the optimization changes the behaviour?

Thanks!

p.s. adding debug (printf) lines, clearly changes the optimization and then changes behaviour...

Let me try to run the NDK example with optimization enabled (like release mode) and update you.

Thanks, now with debug printf lines in the code, it works as I want for Opt=3.

Look forward to hearing back about your investigations.

Dear David,

I didn't see the behavior which you are facing.

C:\ti\mcsdk_2_01_02_06\examples\ndk\helloWorld\evmc6670l

I did like below and recompiled the project then I ran like below.

C:\ti\ndk_2_24_02_31\packages\ti\ndk\winapps>helloWorld.exe 10.100.1.33

Testing UDP echo server at 10.100.1.33:7

Received back 13 bytes.
Data echoed: Hello, World!
Exiting test. Time = 0 seconds

C:\ti\ndk_2_24_02_31\packages\ti\ndk\winapps>

Also I did "Optimize code size" as '0'

Thanks, this also works for me, I have realised.

The issue is when I try to send back a different string from the string received, so in udpHello

sprintf(sendBuf,"18,15,14\0");

...

sendto( s, sendBuf, strlen(sendBuf, 0, (PSA)&sin1, sizeof(sin1) );

the behaviour is very strange in Release mode. Can you try that and see what you get?
