What is TEXT_BASE?
Hello,
I'm just trying to build barebox for the first time, for processor OMAP4 and board Phytec phycore pcm049.
Now i have to enter something for "TEXT_BASE", what should i select?
And in general, are there some important settings beside selecting the processor and board, or are the default values good for the first try?
bye
Norbert

TEXT_BASE is the address barebox will be linked at. Normally this is somewhere near the end of SDRAM, but could be also in some internal SRAM in special cases. If you use the pcm049_defconfig it should be configured correctly already.

Ok, thanks, i didn't know there are those configs.
Now it's building and produces some files. Is there somewhere an explanation what the files are and what i should do with them in the next step? In my case with an OMAP based board? I would have expected at least the "MLO" file, but there are just the barebox files..
I don't intend to get personal teaching lessons here, but the whole documentation is somehow - suboptimal. I am writing down the steps i'm doing, so in return i could add a howto or tutorial or something like that.
bye
Norbert

For OMAP boards there are two defconfigs, one for the MLO (or xloader) and one regular barebox binary. See
http://wiki.barebox.org/doku.php?id=boards:omap
(I just saw it's a bit outdated, because the file generated for the xloader is nowadays MLO, not barebox.bin.ift.
So you have to:
make pcm049_xload_defconfig
make
cp MLO /mnt/MLO
make pcm049_defconfig
cp barebox.bin /mnt/barebox.bin

That would be great. I could give you an account for the wiki if you have something to improve there.
Thanks
