Is your application asking for the permission to write to the external storage?
The original build of the TC70, even if based on Android v4.4.2, does have some special settings that make it handle the external storage in a similar way to Android 4.3 and older versions.
So, even if, on Android KK, the permission is not needed to write in your own package folder (I imagine that your app package is com.tup.crashreport), you may need that setting on the original TC70 BSP.
My suggestion would be to update your TC70 to a newer build if this can be an option.

the permission to write is granted in the Manifest.xml file. I found the solution: change the logcat command
cmd = "logcat -vtime -f " + filename.getAbsolutePath() + " -n2 -r1024";
and it works.
Thank you for your tip.
