I'm no expert, but I can try to help you figure it out. Let's start with something simple. What version of LegOS are you using? How are you starting the 'task_swapper' task?

(...) With the default CONF_LNP_HOSTMASK (0xf0), the host adress is encoded in the higher 4 bits, so you should write #define CONF_LNP_HOSTADDR 0x10 Eric (22 years ago, 5-Jul-02, to lugnet.robotics.rcx.legos)
