You could store MAC addresses for each individual board in non-volatile memory, then read the MAC address from there each time U-Boot runs, and program your Ethernet ports accordingly. ---------------------------------------------------------------------- Message: 1 Date: Tue, 10 Apr 2007 16:51:04 +0200 From: powerpc440 Subject: Multiple Boards with same MAC addresses - problem. To: linuxppc-embedded@ozlabs.org Message-ID: <461BA458.2010605@googlemail.com> Content-Type: text/plain; charset=ISO-8859-1 Hello all, I have multiple boards, based on ppc405ep (which include on-chip two ethernet ports). I'm configure the MAC address in u-boot and all works great. The problem appears when I use two or more boards in one network, because the MAC addresses are the same. Now I'm making a own u-boots for each board, but this solution is not very comfortable. My question is, which is the standard way to resolve such problem? I would have only one generic u-boot. Is this possible? Best regards, Zhivko Yordanov ------------------------------
