Attached are two source files of a simple USB demo.
|
||||
|
||||
https://www.rtems.org/bugzilla/show_bug.cgi?id=1601
|
||||
|
||||
The FreeBSD initialization is performed in mi_startup() (file
|
||||
init_main.c). Use the demo and single step through this with the
|
||||
debugger. A lot is done with linker sets, e.g. the driver initialization.
|
||||
|
||||
Look at c/src/lib/libbsp/arm/shared/startup/linkcmds.base and search for
|
||||
"_bsd".

||||

||||
