WEC7 Memory Leakage

Other Parts Discussed in Thread: AM3505, AM3517

Hi,

I use AM3517EVM and WEC7, and found memory loss problems.

I use C # to write a small program to reproduce this problem.

The program includes twenty Label with a Counter and Timer.

In every Time Tick Counter++, and display on the Label.

In this way memory is consumed very quickly.

But the problem did not occur in the WCE6.

When the program is closed, loss of memory has not been released.

I can provide the test program via email.

thx.

ps. So far, I can identify the WindowsAPI DrawText() will have this problem.

Use demo tests are normal, it should be image error, I would clarify the issue.

When I use the AM3505 with PowerVR will have this problem, if it is AM3517 withPowerVR on normal, but this problem only occurs in WEC7, but WCE6 is OK.

I have the same issue in WEC7, but to reproduce it you simple have to copy/paste files from two different folders. Here is the script I used to do the test:

:startover

copy \temp\*.* \q

del \q\*.* /q /f

goto startover

If you start the script and keep looking at memory used (control panel->system->memory) you can see the issue.

In \temp there are 50-60 files of different sizes.

I have a custom board with 37xx full.

AM3505 does not have Graphics Accelerator so how can you use PowerVR?

I do not use PowerVR, I just do not remove this module.

WCE6 NK.bin did not remove the PowerVR, is OK.

But WEC7 NK.bin, encountered this problem.
