Hi igor,

I can find the patch at this link, but it does not provide any patch to add memtool source code.

In my AndroidKK4.4.2 BSP does not have "/test/memtool/" folders.

Regards,

Peter.

Hi Peter

as far as I understand it just adds linux memtool package

to build Android.mk (Android is based on Linux):

LOCAL_MODULE := memtool

after that one needs to rebuild Android.

Best regards
