[U-Boot-Users] u-boot for SC32442B

dear ,all
I have a board use S3C2442B43 (400MHz, 64MB mSDRAM, 128MB Nand),and there is no flash or other memory,so have to use the nand boot,is there someone have done something for this ,please give me some advices,thanks. _________________________________________________________________ 天凉了,添衣了,心动了,“七件”了 http://get.live.cn

Hi Tangwei
I have a board use S3C2442B43 (400MHz, 64MB mSDRAM, 128MB Nand), and there is no flash or other memory,so have to use the nand boot, is there someone have done something for this, please give me some advices, thanks.
Booting from NAND flash usually requires some special provisions as code can not directly be executed from it. Have a look at nand_spl and its documentation in doc/README.nand-boot-ppc440 describing the process applicable to PowerPC SOCs. As I don't know much about the S3C2442B I can't give you any concrete advice there, but you will have to find out from its documentation whether and what its NAND booting provisions are.
Cheers
Marcel

the patchset in http://svn.openmoko.org/trunk/src/target/u-boot/patches/ supports exactly this CPU with full boot-from-nand support. Please check the gta02 board configuration in that patchset.

thanks,
i have note this,but i think the project they created is in a mess, inorder to use it: first, you must have to spend much time to figure out the patch's order; second, i consider some of their patchs are not placed correctly in u-boot's directory; the SC32442B43 is a complete minimal system for u-boot and linux,i just want to build a minimal system.

There is no S3C2443 support in mainline u-boot at this point.
I once started working on it, but it was never finished, as I was doing this in my spare time. At the moment it is unlikely that I'll be able to do much about it, since I don't have any S3C2443 based hardware at thos point.
The Samsung BSP for the SMDK2443 contains a modified fork of an old u-boot version, as far as I remember.
Cheers,

The patchset in question is a 'quilt' patchset, and all you have to do is
1) check out latest u-boot.git 2) check out the patchset and put it in a 'patches' subdirectory 3) do 'quilte push -a' 4) do 'make gta02v4_config && make'

hello Harald Welte
today i spend some more time to browse all the patchs in the web you have remind me again.and have gotten more, it is because: 1)i read less about the patchs before; 2)your patchs's info is a little less; that induced i think your project is in a mess,i apologize for the before letter,you have really done a very good job, i will try to build my minimal system in the reference of your patchs. by the way can you give me the gta02v2's schematic,thanks
B.R.

I am afraid this is not possible, since the product is not yet in the market. As far as I know, the schematics might be available under a permissive NDA (and NDA that allows you to write free software such as u-boot), but only after the product has entered MP and is available in the market.
Please feel free to contact michael@openmoko.org about this.
You might find some of the information at http://wiki.openmoko.org/wiki/Bootloader and http://wiki.openmoko.org/wiki/Bootloader_commands helpful.
