From 23a70bf9c352ec5b6ac52d5be8087b963c2073dd Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Tue, 31 May 2011 21:01:47 +0000 Subject: [PATCH] net/net.c: Update ipaddr if the environment has changed At least on ARM the ipaddr is only set in board_init_r function. The problem is if ipaddr is not defined in environment importing another environment defined don't update the ipaddr value. For example, suppose we've a default environment without net variables defined and we want to import an uEnv.txt environment from SD-card like this: ipaddr=192.168.2.240 netmask=255.255.255.0 gatewayip=192.168.2.1 serverip=192.168.2.114 Then if you try boot from NFS results in: Importing environment from mmc ... Running uenvcmd ... smc911x: detected LAN9221 controller smc911x: phy initialized smc911x: MAC ac:de:48:00:00:00 *** ERROR: `ipaddr' not set The ipaddr at this point is NULL beacause is only set at board_init_r function. This patch updates the ipaddr value if the environment has changed.
