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 ?
