I have seen that - they are also included and compiled into the .a static libraries. For a reason I do not understand, this is not get linked with my code - that is why I asked. On Wed, Feb 17, 2016 at 12:02 PM, Tim Newsham wrote:

Those functions exist in libplatsupport/src/plat/am335x/dm.c in some source trees I have. (I don't have any experience with camkes and never tried to build it for am335x...)

I am trying to develop a camkes application with one component having access to the timer. I got some inspiration from the time server for the kzm machine. Now, I am trying to port that to the am335x machine to execute on a beagleboard black.

I dig into the code and found the appropriate platform-specific functions to call. Unfortunately, when trying to compile, it fails (see below).

Anybody has an idea why this happens?

Also, if you want to look at the camkes application, I put it on github at https://github.com/juli1/sel4-experiments/tree/master/camkes/pingimpl-am335x

Thanks for any help!
