Apr 12 17:03:42 <ayaka> I have some problem with nand map in s3c24xx and s3c6410. I hear that s3c6410 can map the begining 4K of nand after run internal rom as s3c24xx do. is that true?
Apr 12 17:04:46 <ayaka> and if is true, how does u-boot make 4K content the necesary code to load the rest u-boot whose size is more 128K
Apr 12 17:06:18 <lindi-> ayaka: "after run"?
Apr 12 17:06:52 <ayaka> I meant, the SoC execute code in its internal rom
Apr 12 17:08:00 <lindi-> ayaka: afaik on freerunner the first 4096 bytes of NAND is read to stepping-stone RAM and then the CPU starts executing code from the beginning of that RAM area
Apr 12 17:08:53 <lindi-> ayaka: I don't think it maps NAND, afaik it actually copies the 4096 bytes
Apr 12 17:09:29 <ayaka> yes, it is called stepping-stone, I don't know what is the name of that memoey area in datasheet.
Apr 12 17:09:59 <lindi-> ayaka: maybe it uses the CPU cache for that?
Apr 12 17:10:19 <ayaka> ok, then how does u-boot make beginging 4K contents those code
Apr 12 17:10:32 <lindi-> ayaka: hmm?
Apr 12 17:11:02 <lindi-> ayaka: the first 4K sets up RAM and then reads rest of u-boot from NAND I guess
Apr 12 17:11:06 <ayaka> Is your u-boot not larger than 4K
Apr 12 17:11:15 <lindi-> ayaka: I use qi but the same principle applies
Apr 12 17:12:42 <ayaka> sorry, I want to know in that case, the u-boot can't be larger than 4K, can it?
Apr 12 17:12:56 <lindi-> ayaka: sure it can
Apr 12 17:13:32 <lindi-> ayaka: the first 4096 bytes enables RAM and then copies rest of u-boot to RAM
Apr 12 17:14:23 <ayaka> yes, but how does u-boot put necessary code in the first 4K of its image when it is built
Apr 12 17:14:37 <lindi-> ayaka: with some linker script?
Apr 12 17:15:04 <lindi-> ayaka: it's probably in a specific ELF section and then it can use objdump to make sure that is in the beginning of the image
Apr 12 17:15:09 <ayaka>  ok, I will see makefile
Apr 12 17:15:11 <lindi-> objcopy
Apr 12 17:16:09 <ayaka> yes, I have seen that cmd, but I don't know much about that cmd
Apr 12 17:17:29 <ayaka> thank you, lindi-
Apr 12 17:18:04 <lindi-> ayaka: you are asking the right questions but I it is sometimes difficult to understand your english
Apr 12 17:19:45 <ayaka> I am very sorry, could you point out which sentences is not correct
Apr 12 17:20:46 <ayaka> or not perfect
Apr 12 17:22:05 <lindi-> I already asked about that "after run" part
Apr 12 17:22:25 <lindi-> I guess you meant "after running from internal ROM"
Apr 12 17:23:43 <ayaka> yes, but I am sure the verb style in after and before sentences, I think I need did or do
Apr 12 17:24:42 <ayaka> I will review this part, is that the only one
Apr 12 17:26:19 <lindi-> "how does u-boot make beginging 4K contents those code" -> "How does u-boot ensure that the first 4K contains that code?"
Apr 12 17:30:55 <ayaka> I see, thank you
Apr 12 17:31:06 <ayaka> is that all?
Apr 12 17:31:18 <lindi-> it's all I can fix today :)
Apr 12 17:33:14 <ayaka> thank you very much
Apr 12 17:33:56 <ayaka> I will write more competition to improve it
