The system can boot up but the network can not access the external network. This used to work in Yocto 1.6. ############################## # ifconfig eth0 eth0 Link encap:Ethernet HWaddr 52:54:00:99:41:3C inet addr:169.254.202.151 Bcast:169.254.255.255 Mask:255.255.0.0 inet6 addr: fe80::5054:ff:fe99:413c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10 errors:0 dropped:0 overruns:0 frame:0 TX packets:40 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2294 (2.2 KiB) TX bytes:9431 (9.2 KiB) # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default * 0.0.0.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 ############################## The eth0 is set an invalid ip 169.254.x.x, it should be 192.168.122.x. After some more testings, I believe it is a connman issue. I tried connman 1.22 (the version in Yocto 1.6), 1.23, 1.24, 1.25 (The current version in master/dizzy), and 1.26. The 1.24 and 1.25 don't work, and others work well. Here is the output for connman 1.26: ############################## # ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:99:41:3C inet addr:192.168.122.252 Bcast:192.168.122.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fe99:413c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:20 errors:0 dropped:0 overruns:0 frame:0 TX packets:80 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2307 (2.2 KiB) TX bytes:16016 (15.6 KiB) # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default pek-yocto-build 0.0.0.0 UG 0 0 0 eth0 192.168.122.0 * 255.255.255.0 U 0 0 0 eth0 192.168.122.1 * 255.255.255.255 UH 0 0 0 eth0 ######################## So, the easiest way to fix this issue is upgrade connman to the latest version (1.26) 46738 1 cristian.iorga 2014-11-04 06:35:47 +0000 Connman upgrade to 1.26 will get integrated soon. 46885 2 cristian.iorga 2014-11-08 08:30:22 +0000 Fixed with commit: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=40b3888e409631bb2ceb64b0954af22f6c8dae48
