cross compiling Uboot

[vibnwis]

Hi there,
This is driving me crazy. I just don't what files and how to edit the required to point to the tools-chain. I could set the gcc of the tools chain but not their libs as well as the header files. Has anyone compiled Uboot in using cross-compiler? Any advice is welcome.

Thanks

Hi,

Here is a reference link for how to build uboot source code on CD-ROMs.

I've been able to compile it well. The uboot from denx doesn't support the S3C2440 processor but the openmoko.org uboot implementation does. It compiles well but I haven't tested if it really works.
good luck

Great! May I know what version of OpenMoko u-boot is it? also did you compile using MacOSX GCC4.3.2 tools chain? I recently managed to hack into some files of U-boot 1.1.6, and it finally worked out. However, I don't to give it a try on the OpenMoko you just mentioned.
Thanks

I can only find QQ2440 config in the .tar file in the ftp here, no trace of the MINI2440. That QQ config file is also not present in the u-boot git tree

So, is the QQ compatible with the mini ?

trying to sort out the huge mess that is software for that board.

+ the u-boot 1.1.6 present here at esky-dh does'nt have support for the 2440, only 2410
+ the u-boot 1.1.6 present at develpmentboard.net has support for 2440
+ however, that months old patch is not in u-boot git tree
+ the develpmentboard.net u-boot doesn't know about mini2440, only the QQ

In other words, despite the board description everywhere, the mini2440 doesn't have u-boot support. Including the source code doesn't count

I managed to get a patched u-boot 1.3.4 version on the board. It's still 'ancient' and the patch doesn't apply to the u-boot git tree, but it's progress... Haven't tested it all tho.

I now got a full u-boot working, instead of trying to work on the official u-boot tree, I started from the openmoko one, since they already have basic 2440 working.
I had trouble with starting from nand but now it all work, including MMC, network, etc etc. Nice to have a proper bootloader !

Now for the kernel. Thats toughter, right now the kernels I make don't even display anything and hang silently :/
