[okl4-developer] I have a question about OKL4 code

[Gabi Voiculescu]

I think (but am not sure) that this function is only supposed to change cpu mode from SVC (supervisor) to USER.

Somebody please correct me if i'm wrong.

hi , I m reading the OKL4 version 2.1 for armv5 code, i have a qestion that the idle kernel thread creates the root server thread,but its handler function(initial_to_user) do nothing:
         BEGIN_PROC(initial_to_user)

        SET_USER_DACR
        RESTORE_ALL
        subs    pc,     lr,     #1
        END_PROC(initial_to_user)

it seems run forever, because there is no thread except idle. So how I create /delete other threads based L4?
