Hello Marek,

Please CC the CoreSight mailing list when asking questions as someone else may also be able to answer.

First and foremost I advise using the official CoreSight kernel found on the openCSD site [1] rather than my personal branch [2] - you never know what you'll get with the latter.

That being said the CoreSight kernel on the openCSD site is not an Android kernel - it is simply a mainline kernel supplemented with patches that haven't made their way to mainline yet. You will have to either add the android patches to the CoreSight kernel or the other way around (CoreSight patches on android kernel).

Android user space is also different and does not include the perf-tools. You will have to add them manually along with the dependencies they require. I haven't gone through that process and as such can't advise more on that portion.

Get back to me with your questions if the above isn't sufficient.

Best regards, Mathieu

Hello Mathieu,

I'm sorry for bothering but I think you may be person that can help me. I'm trying to install and run Android on Juno Board r0. I tested Android 17.05 from Linaro and it works. Now I'm trying to have a perf using Coresight but I'm little confused. Do I need to build Android from Linaro and the kernel from here https://git.linaro.org/people/mathieu.poirier/coresight.git/ or here https://github.com/Linaro/OpenCSD/tree/perf-opencsd-4.12. Any help with this will be appreciated :)
