Hi all,
I'm running L4Linux on the Fiasco V2 microkernel on a Pentium IV. I am also running other L4 applications beside the L4Linux kernel. I would like to be able to print debug messages from those applications to the serial port. Messages print fine until L4Linux boots up. As best as I can determine, the problem is that L4Linux gets control of the serial port, and so no other tasks can use it. There may be a way to get this working using the L4Env setup; however, I am trying to keep a very minimal setup and so do not want to use L4Env. Can anyone provide some pointers on how to best go about restricting L4Linux's access to the serial port?
Thanks!
