uboot patch/source mismatch

I tried to follow Jeff's link http://jeff.doozan.com/debian/uboot/build_uboot.htm to build uboot from source, but patch failed for "makefile" in "/tools/env".

After adding "-static" to "makefile", I got many SDRM related errors.

Has anyone tried to build uboot recently?

Does anyone know how to roll back to old source code?

You should find the old sources here: http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=shortlog

grab the tarball (link is labeled snapshot) or use git

Thanks.

I found "u-boot-a59e27997637a2395ae2cc7f809127f24119a167.tar.gz" (06/2010).

It seems to me download "tarball" is most preferable to avoid source/patch mismatch.

Also tarballs seem much faster to download.

I don't think I'm going to use git or snv to download source again.

@DockstarPBX,

Yes, I tried to compile u-boot source from Oct 5 and it does not compile.

It looks to be that some source files are trying to be compiled without having CONFIG_SYS_ARM_WITHOUT_RELOC defined.

I have rolled back to 2010.06 source code and built "doimage" from Pogoplug uboot source code to build "uboot.mtd0.kwb".
However, the "uboot.mtd0.kwb" failed to boot from SDRAM. The patch from Jeff's link may not be the one Jeff used to build his recent mtd0 uboot.

@ygator
I downloaded latest u-boot, patched it with my patch and take your build steps. When I set TEXT_BASE to 0x00c00000 it's running on dockstar at 0x800200.
They made changes to relocation, you can read more here.

nevtag and ygator,

Your posts on building mtd0 u-boot are very helpful and I'm trying to catch up. Currently I'm following your steps to build u-boot on Dockstar and found it's more convenient than build u-boot using cross compiler on Debian on VirtualBox.

I'll read the link about your patches for new u-boot source code. I got only few hours each day for Dockstar, but I'll try to catch up.

Thanks

@nevtag

I am not sure how you are getting it to compile.
I just git the latest uboot and did not patch anything.
I did a:
make mrproper
make sheevaplug_config
make u-boot.kwb

It did not compile. It blew up trying to compile arch/arm/lib/board.c.
So the original source does not even clean compile.

I use the git command Jeff posted in compiling u-boot.
git clone git://git.denx.de/u-boot.git u-boot

The master branch of the u-boot tree has "moved on" since then, and now has a bunch of ARM-related changes that cause the Marvell boards not to compile (yet).

If you go back to the current stable release you should have better luck applying the patches and compiling:

git co v2010.09

After changing "mkDockstar.mtd0"
from "sed -i 's/^TEXT_BASE = 0x00.00000/TEXT_BASE = 0x00600000/' board/Marvell/sheevaplug/config.mk"
to "sed -i 's/^TEXT_BASE = 0x00.00000/TEXT_BASE = 0x00c00000/' board/Marvell/sheevaplug/config.mk"

I was able to build mtd0 uboot from 2010.06 source, tested it on SDRAM and flashed it to NAND.

I'm not sure why Jeff set TEXT_BASE to 0x00600000 in his patches and mkDockstar.mtd0.

@ygator

You need to add this to include/configs/sheevaplug.h

/* additions for new ARM relocation support */
#define CONFIG_SYS_SDRAM_BASE           0x00000000
/* Kirkwood has 2k of Security SRAM, use it for SP */
#define CONFIG_SYS_INIT_SP_ADDR         0xC8012000

I downloaded 2010.09 release u-boot tarball, applied all Jeff's patches (including the patch to set TEXT_BASE to 0xc00000) and your above changes, I was able to build "u-boot.mtd0.kwb", but it hang at:

go 0x800200
## Starting application at 0x00800200 ...

tar -xzf u-boot-2010.09.tar.gz
cd u-boot
patch -p1 < 2010.09-LED-SDIO.patch
chmod +x build

./build

If you load u-boot to RAM, u-boot uses the environment in mtd0.
If you dont want this, disable nand environment, but enable it if you write u-boot to flash, otherwise you couldn't change the env parameters.

I was able to apply you patch to 2010.09 source with a single error on "/tools/env/Makefile": I added "-static" manually.
I was able to run "uboot.mtd0.kwb" from 0x800200 using Jtag or from 2nd stage u-boot but it not from mtd0 u-boot.

If you flash it too mtd0, check out if 0x00600000 for TEXT_BASE works.
I have the feedback that the u-boot works on mtd0.

Either 0x00600000 or 0x00c00000 for TEXT_BASE worked.

I did a search of "TEXT_BASE", it didn't seem "TEXT_BASE" was used for "Marvell" or "sheevaplug" in uboot source code.

See arch/arm/cpu/arm926ejs/start.S and Makefile.

I did search on Windows, it missed "start.S" for some reasons. Comment in "start.S" says:

*
* do important init only if we don't start from memory!
*
Is the "TEXT_BASE" used when u-boot is loaded to and executed from SDRAM "Destination address" and "Execution address" in u-boot headers?

u-boot header:

filename = c:\Dockstar\uboot-original-mtd0.kwb
Boot from NAND
Default ECC
Page size = 2048 Bytes
Image size = 470268 Bytes
Source address = 0x00000200
Destination address = 0x00600000
Execution address = 0x00670000

I found when "TEXT_BASE" of mtd0 uboot was 0x600000, uboot was only relocated to 0x600000, when "TEXT_BASE" of mtd0 uboot was 0xc00000, uboot was relocated to 0x600000 and 0xc00000.

I believe mtd0 uboot can't be loaded to SDRAM and run from SDRAM by another mtd0 uboot because they are relocated to the same SDRAM address 0x600000. To test mtd0 uboot in SDRAM, it should be loaded using Jtag or from a mtd3 uboot with different relocate address (0xc00000).
