Re: [tcf-dev] Help regarding removing OS dependencies in TCF C agent

Hi Shashanka,

 

Yes, it is possible to run TCF agent on baremetal. I have done it and it works very well. You would need to develop an alternative baremetal implementation of several modules: asyncreq.c, mdep.c, mdep.h, mdep-inet.h and mdep-threads.h. You also will need baremetal implementation of TCP/IP and, optionally, file system. I used lwIP and FatFs. “Easy” is relative term here – it is a lot of work. Using RTOS is also a good option. And it should be much less work.

 

> I am not sure how to proceed with removing OS dependencies from these functions.

 

You provide your own implementation of OS functions.

 

Regards,

Eugene

Subject: [tcf-dev] Help regarding removing OS dependencies in TCF C agent

 

Hello,

I am trying to port TCF C agent to a microcontroller. I have come across few files like mdep.c or events.c which heavily use threads and other OS functions. I am not sure how to proceed with removing OS dependencies from these functions.

  1. I tried to search for libraries that can mimic thread handling without using an OS but couldn't find one. Is there a way not to use these and achieve a real baremetal (No OS) TCF agent? 
  2. I read in this TCF homepage that it should be easy to port to a baremetal platform. Does that mean without OS or with an Real-time operating system (RTOS)?

It would be helpful if I can get to know in which direction I can proceed. 

Regards,

Shashanka Navada
