Hi,
I'm currently working on updating the firmware on our custom board (based on IBM walnut board) and tried to build the latest released u-boot 2011.06 using ELDK4.2.
Using the fresh source code extracted from u-boot-2011.06.tar.bz2, I did "make walnut_config" and then "make". But I get the following error.

ppc_4xx-ld:u-boot.lds:1: parse error
make: *** [u-boot] Error 1

All of the code compiles. I think it's a linker error but I have no idea how to resolve the problem.
Any help would be appreciated.

There is no such problem with walnut board in the v2011.06 release. Please double-check our source.

Thanks for the reply.
I was in the process updating ELDK from 4.1 to 4.2 and must have had something screwed up. I tried again Today and it compiles without error.

Thanks for looking into this and helping a newbie.

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 at 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

--------------------- SUMMARY ---------------------------- Boards compiled: 1
Boards with warnings or errors: 1 ( walnut )
----------------------------------------------------------
[root at new-linuxdev u-boot-2011.06]#

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.

I'd appreciate some guidance.

Thank you in advance for any help and thank you all for putting such wonderful software in public domain.

Sorry to keep relying to my self.
It seems that the tool that generates u-boot.lds does not like // in the header file and putting it in the u-boot.lds file.

I started using /* */ instead and it compiles OK now.

Thanks.

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

include/configs/walnut.h +0 -1

@@ -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...

The problem must be with your own changes to the config file, especially with your way to "comment out" the #define.

Thank you for the information. I'm just re-learning my way around u-boot. I appreciate your comments and pointers. Last time I used u-boot, it did not use the current method for configuration and I was able to us // to comment stuff out in the configuration header file.

Thank you and you guys rock!
