I understand what your mean. But we need to setup the boards' information including the MAC address through ethernet. With the same MAC address, only one board can be configured at a time, which is not efficient enough.
Because of the quantity of the boards comparing with the number of workers, we can not set the MAC address by hand. So what I means is to make the u-boot generate a temporarily random local-administration MAC and get the correct information later. May I know how other set their boards' MAC address. Is there any trick to do this job. 2010/2/8 Wolfgang Denk <w...@denx.de>: > Dear Peter Pan, > > In message <48abf2c21002072147t7e67ba44i4298b39acc5d7...@mail.gmail.com> you > wrote: >> Recently, we had a issue that we need to start more than one board at >> a time.
