Hello again,
as mentioned before i'm writing a char module for L4linux.
I want the L4Linux driver to communicate over l4_ipc to another L4-Task.
Well, there's a compiler error:
Building modules, stage 2. MODPOST 1 modules ERROR: "l4_utcb_wrap" [drivers/char/myDrv.ko] undefined!
This appears, when trying to write in mr[].
l4_msg_regs_t* mregs = l4_utcb_mr_u(utcb); mregs->mr[0] = 23; // if i comment this line, build works.
I doesn't crash at runtime, it just don't compile. Any idea?
BTW: Adam made a hint to use L4XV_FN* wrappers. When to use them, and what are they for?
Thanks, ba_f
