Problem is that default environment is not setup correctly. Only bootargs is set. No bootcmd, netmask, ipaddr, serverip is set. Should they be defined differently in configuration file than what they are defined

version 1.1.2 in order to get them to default environment?
Sorry, but I fail to understand you here. Please give an example.
Okay, if I put the U-boot to new unit or if I erase the environment sector from flash the U-boot uses default environment since there are none in the flash. Correct?
In U-boot version 1.1.2 that I was using, I could set that default environment by setting the #defines in include/configs/ixpd425.h like this:
#define CONFIG_NETMASK 255.255.255.0 #define CONFIG_IPADDR 192.168.11.201 #define CONFIG_SERVERIP 192.168.11.10
#define CONFIG_BOOTCOMMAND "cp.b 0x500a0000 1700000 0x17FFFF; bootm 1700000" #define CONFIG_BOOTARGS "console=ttyS0,115200 root=/dev/mtdblock3 rootfstype=jffs2 mtdparts=phys_mapped_flash:0x80000@0x0(uboot),0x20000@0x80000(env),0x1e0 000@0x0a0000(kernel),0x1c00000@0x280000(rootfs) mem=128M\0"
But in the latest U-boot from git(u-boot-ixp) only the BOOTARGS gets defined when the default environment is in use and none the other values. Has this been changed since 1.1.2?
Is there a way to get some indication that something is happening?
Not sure if this is welcome. The "cp" command is not a (NOR) FLASH specific command, but a memory subsystem command. So a change here would also affect a copy from memory to memory too.
Humm, I'm not sure if the U-boot 1.1.2, that I'm currently using, is modified more than I though because there is 'rolling line' indicator when copying stuff to flash.
It would really nice to have any indication that something is going on because it may take up to 15-20 minutes to program whole flash, but if there is no such thing then I think I'll have to see if I can do something. First I have to find place where to put it.
And speaking of mailing a patch. Are there instructions how to get the patch from the code? I have only applied patches, but never actually done them. There were some sort of list what are required in a patch, but how to get the patch itself.
