I tried this version. I still didn't get it working, but some improvements. What I changed is: * call eth_send() instead of edev->send directly. This makes sure the carrier is initialized correctly * implemented pico_zalloc as memalign(32, x); memset(ptr, 0 x); Some drivers (such as fec_imx.c I tested with) need bigger alignment for network packets to be able to do DMA transfers. * move picotcp_net_init from coredevice_initcall to device_initcall. In my case the poller infrastructure is not available during coredevice_initcall and barebox crashes. Maybe the poller infrastructure could be made more robust here, but we don't want to to networking in this early stage anyway, right? * select POLLER is missing With this I get: barebox@Phytec phyCORE-i.MX27:/ ifconfig eth 192.168.23.67 255.255.0.0 up Assigned ipv4 192.168.23.67 to device eth barebox@Phytec phyCORE-i.MX27:/ picoping 192.168.23.4 eth0: 100Mbps full duplex link detected ARP: Destination Unreachable ARP: Destination Unreachable ARP: Destination Unreachable ARP: Destination Unreachable ARP: Destination Unreachable ---- Ping timeout!!!
