Hi Joel,

 

To make long story short, I’ve committed a script, which creates a git repo for agent porting project.

The repo is an example of how to start such project.

 

Run the script:

org.eclipse.tcf.agent/agent/bin/create-agent-project -n rtems

 

Then look into tcf.agent.rtems/system/rtems/tcf/context-rtems.c.

It contains stubs of all functions you need to implement using debug APIs available in RTEMS.

HTH.

 

Regards,

Eugene

Hi

 

I am starting to work through porting the TCF Agent to RTEMS. RTEMS is a single process, multi-threading open source RTOS. Executables are usually statically linked and the TCF Agent is running as a thread.  I have pushed through the build system and gotten the Agent running enough for the portable services to work. By that, I mean those services that compiled out of the box. This is enough to have the FileSystem service working.

 

I am now feeling a bit overwhelmed with a list of services that have names that seem like I want to enable them but I don't know which are the minimum required. I am sure we don't want any that resolve symbolic information on the target and SysMonitor that depends on /proc which RTEMS does not have.

 

Which services should I focus on? 

 

I started on RunControl which quickly got me into addressing context area definitions and ptrace(). I don't see any other way to implement this in the git source, so my current plan is to implement a minimal ptrace() for RTEMS. 

 

What needs to be done to present a single process and multiple threads via the agent? 

 

Is there any guidance on which Services support which perspectives in Eclipse? How can I know when I have done enough to make a specific perspective work?

 

Sorry to ask so many questions. There is a lot of magic to decipher and adapt.  :)

 

Thanks.
