How to link my application to eCos is the part that I'm stuck.
1) Does eCos Configuration Tools (ECTs) have some options that I can set
and link my program?
If it does, could you please let me know?
I did set Startup type* to ROM for building a standalone application, but
I don't know how this is linked to my application.
2) Or, is it true that I can't use the ECTs to link eCos with my
application?
- what are steps for linking an application to eCos?
- or please refer me some documents that could help me on this. (I read
user's guide, ref, and started guide, but I still has no clue on this)
Thank you.
