Subject: Basic bare metal ARM domain interface
Date: Wed, 25 May 2016 19:42:20 +0000 [thread overview]
Message-ID: <65387702CB408A468385A8FFC6F5807C342E87@POSTAR.fer.hr> (raw)
Hello,
I'm working on bare metal application for ARM Cortex A7/15 on Odroid XU3
platform. I'm using Xen 4.6.
After successfully creating bare metal example(by successful I mean I've stuck
processor in while loop in main function), I probably should initialize memory
management unit and similiar. I've found FreeRTOS project on Github where
similiar stuff was done for ARM Cortex A15. Project is done for Xen 4.4.
Xen FreeRTOS project: https://github.com/GaloisInc/FreeRTOS-Xen/ .
1) I'm using 4.6. so I don't know if code from is fully compatible? (I had to
comment out lot of things because they block program, printing for example)
2) Additionally , I would like to implement basic serial output to dom0 from my
bare metal domU. What is the minimum one should do for implementing console
output?
3) Furthermore, as this should be bare metal application, I would like at least
to be able to toggle LED. How can interface hardware from domU? My first guess
would be to directly address Exynos 5422 GPIO registers but I don't know if
that would work beacause application is running on VCPU (probably not??) ??
Any answer, example of implementation, specific documentation or advice would
be very helpful.
Thank you in advance...
Regards,
Ivan Pavić
