Dear "Brian S. Park",
In message 4E80BC71.4000802@corelis.com you wrote:
I found my problem.
My board, though based on walnut board, does not have real time clock. So, I have to disable RTC support in u-boot. However, as soon as I comment out
#define CONFIG_RTC_DS174x 1 /* use DS1743 RTC in Walnut */
in walnut.h, line 68, I get build error.
[root@new-linuxdev u-boot-2011.06]# ./MAKEALL walnut Configuring for walnut board... ppc_4xx-ld:u-boot.lds:1: ignoring invalid character `#' in expression ppc_4xx-ld:u-boot.lds:1: parse error make: *** [u-boot] Error 1 ppc_4xx-size: './u-boot': No such file
Well, you fail to tell us how exactly you "comment out" this line, but apparently exactly this is your problem. If you just remove this line, like this:
index d10f748..e5a17a6 100644 --- a/include/configs/walnut.h +++ b/include/configs/walnut.h @@ -65,7 +65,6 @@ #define CONFIG_PHY_ADDR 1 /* PHY address */ #define CONFIG_HAS_ETH0 1
-#define CONFIG_RTC_DS174x 1 /* use DS1743 RTC in Walnut */
/* * Commands additional to the ones defined in amcc-common.h
you would get another type of build errors:
-> ./MAKEALL walnut Configuring for walnut board... common/libcommon.o: In function `do_date': /home/wd/git/u-boot/work/common/cmd_date.c:60: undefined reference to `rtc_reset' /home/wd/git/u-boot/work/common/cmd_date.c:63: undefined reference to `rtc_get' /home/wd/git/u-boot/work/common/cmd_date.c:72: undefined reference to `rtc_set' /home/wd/git/u-boot/work/common/cmd_date.c:81: undefined reference to `rtc_get' net/libnet.o: In function `SntpHandler': /home/wd/git/u-boot/work/net/sntp.c:70: undefined reference to `rtc_set' make: *** [u-boot] Error 1
...which are pretty much self-explanatory.
By also disabling the "date" and "sntp" commands you would get:
-> ./MAKEALL walnut Configuring for walnut board... text data bss dec hex filename 218714 17552 42532 278798 4410e ./u-boot

I can figure my way out if it's a code problem. This, however, seems like a configuration issue and I'm still a newbie when it comes to u-boot configuration issue. It seems to have changed a lot since last time I looked at u-boot a few years ago.
The problem must be with your own changes to the config file, especially with your way to "comment out" the #define.
Best regards,
