You need to supply some arguments to the simulator when you start
it. The following line comes from the ~/.eCosPlatforms/PowerPC-PSIM

target sim -o '/#address-cells 1' -o '/openprom/init/register/pc 0x100' -o '/iobus@0xf0000000/reg 0xf0000000 0x01000000' -o '/iobus/pal@0xf0001000/reg 0xf0001000 32'
