Help Regarding RVISS

Deepak Sehrawat
Note: This was originally posted on 16th September 2009 at http://forums.arm.com

I have an ARM11 based application running on RVISS. I want to send a message from this application (running on RVISS) to another application running on host computer (windows : on which this RVISS is running). How to do it?

    You could write a peripheral model for RVISS, the implementation of which opened a port for communication.  I played around with writing RVISS models a couple of years ago - it's not trivial!

    If you needs are more basic, you could write out the output of the image running on RVISS to a file using semihosting.  Then read the file from the app running on the host machine.


    We tried the second approach i.e writing to a file from the application running on RVISS using fopen() and fwrite() functions. But that file is not visible in windows file system. (However, we are able to access the contents of that file from RVISS. It seems RVISS is not writing it into window file system but still the contents of the file remains persistent even if we restart the RVISS). Now as the file is not apprearing in windows file system, our host application is not able to read it.

    Secondly, can we communicate with underlying host O.S (windows in our case, on which RVDS is running) via peripheral model approach e.g by opening a port or socket which is visible in windows.
