Hi there: Recently I'm playing with u-boot and want it be able to boot from nand. When I config u-boot to smdk6400, I found I can't get nand_spl with proper size. It need to be pad to 4k to fit into the steping stone. The final size of nand_spl is depend on the variable "PAD_TO":
# PAD_TO used to generate a 4kByte binary needed for the combined image # -> PAD_TO = TEXT_BASE + 4096 PAD_TO := $(shell expr $$[$(TEXT_BASE) + 4096]) The lines above is in file: u-boot-xxx/nand_spl//board/samsung/smdk6400/config.mk Unfortunately the PAD_TO can not evaluate to the proper value when I run the makefile. I change the the line to below: PAD_TO := $(shell expr $(TEXT_BASE) + 4096) then the whole build works OK.
Is there any body think this is an issue ?

Hi, I use ubuntu 9.04 system. The shell is bash version is : GNU bash, version 3.2.48(1)-release (i486-pc-linux-gnu) The make version is: GNU Make 3.81 The step I take to compile the u-boot is : make smdk6400_config make all below is the some message from compiling: arm-linux-objcopy --gap-fill=0xff -O binary /root/u-boot-2009.06/nand_spl/u-boot-spl /root/u-boot-2009.06/nand_spl/u-boot-spl.bin arm-linux-objcopy --gap-fill=0xff --pad-to= -O binary /root/u-boot-2009.06/nand_spl/u-boot-spl /root/u-boot-2009.06/nand_spl/u-boot-spl-16k.bin make[1]: Leaving directory `/root/u-boot-2009.06/nand_spl/board/samsung/smdk6400' cat nand_spl/u-boot-spl-16k.bin u-boot.bin > u-boot-nand.bin

You can notice that the PAD_TO is empty during build, and the final size of the two file is the same. Do you think that is the difference of bash or make between yours and mine cause the issue ? -----Original Message----- From: Minkyu Kang [mailto:promsoft@gmail.com] Sent: Wednesday, September 16, 2009 9:44 AM To: Wolfgang Denk Cc: Minkyu Kang; u-boot@lists.denx.de; sun peng Subject: Re: [U-Boot] I found an error

I think we use similar system. And I saw same problem at my co-worker's system. but I don't know the cause.
This problem is seems to be occurred at particular system. and If your modification have no problem, then we can fix it. so, please send the patch. and then many people will test it.
+ please do not top-post.
Thanks Minkyu Kang
