Hi Bin,
I just found u-boot.rom created from u-boot-x86/testing branch does not have working network any more on QEMU. It is working on the u-boot-x86/master branch.
=> set serverip 10.10.0.100;set ipaddr 10.10.0.108;set netmask 255.255.255.0;set gatewayip 10.10.0.100 => run ramboot *** ERROR: `serverip' not set *** ERROR: `serverip' not set
But 'print' says the env indeed has the 'serverip'. I think there should be something in the upstream that caused this after the u-boot-x86/testing branch rebase. Do you know where might be the problem?
This looks very similar to an issue that got patched on the i.MX6 yesterday by Stefano which said:
commit fd3056337e6fcc140f400e11edd33f6f1cb37de1 "Use env callbacks for net variables" has a side effect on i.MX6 boards because they do not set CONFIG_NET: the ip address results not set, but it is stored in the environment."
Might be something to check...
Regards,
Andy.
