Hello Amadeo, when looking at your output it seems to me that at least the pci-driver, and/or timer services are missing in your configuration (normally they would produce some output), but gPXE's nic-driver depends on them, and won't run without these services. As long as the nic-driver isn't available your lwip-application will block while initializing the lwip-stack.
Please, verify that init's configuration contains at least these items: <start name="timer"> <resource name="RAM" quantum="512K"/> <provides> <service name="Timer"/> </provides> </start> <start name="pci_drv"> <resource name="RAM" quantum="512K"/> <provides> <service name="PCI"/> </provides> </start> <start name="gpxe_nic_drv"> <resource name="RAM" quantum="2M"/> <provides> <service name="Nic"/> </provides> </start> If this doesn't help you, please post your configuration file.
