I have been tasked with figuring out how to auto-generate code that can be executed in an RTEMS operating system after compilation using Simulink Coder. I have no experience with S functions or .tlc files but I am to figure out what needs to be done before I get into learning those.

I have checked the guide on RTEMS' page but I feel that it doesn't explain it very well for someone who isn't experienced with Simulink Coder and TLC files. After that I checked Create a Customized Asynchronous Library which tells me that in order to adapt the available template (which is built for VxWorks OS) I need to customize two blocks in particular: Task Sync and Async Interruption. I have managed to create another set of custom blocks that do exactly the same as these but are linked to a set of .tlc and .c files that I can edit freely. Anyway, upon experimenting some and looking at the files I have the following questions:

Is the customized library guide right to assume that I only need to change these two blocks in particular? Shouldn't I need to create more blocks to encompass all of RTEMS' functions and features?
The VxWorks example that is provided has "tornado.tlc" as the system target file in the code generation settings. Do I need to create another .tlc specifically for RTEMS? Or does "generic real time" option work, provided the blocks' .tlc files are correctly implemented? If I do need to do create another .tlc file, what would need to be set there?
Do the S-functions simply assign parameters defined in the block's mask? That are later used by the .tlc of the block?
Where does the .tlc file of each block tell Simulink Coder what to write? I am not familiar with VxWorks but those files didn't seem to contain the information I expected. I assumed that in some part of the file the code notation/formatting for the target OS is defined but I couldn't find where.
I've read in two places that this is a somewhat straightforward process but it doesn't seem that way to me at all. Am I missing something?
Any tips are welcome

Thanks in advance!
