[U-Boot] Where to find usable CROSS_COMPILE toolchain and the particular config?

[U-Boot] Where to find usable CROSS_COMPILE toolchain and the particular config?

[JIA Pei]

Hi, all:

Sorry for my entry-level question on uboot.

Just start learning how to build uboot, and get some education from
A) http://www.omappedia.com/wiki/Get_started_with_ubuntu_on_omap4
B) http://www.alwaysinnovating.com/wiki/index.php/U-boot_compilation

make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omap4430sdp_config

The above command has been used in A) shown above.
Actually, I myself am working under Ubuntu 12.04, and my target is a
pandaboard ES with omap4460 ...

Two questions:
1) Where to find all the possible CROSS_COMPILE toolchains? and which one
is what I should use?
For example, from B), there are a lot of toolchains, how do I know which
one I should use?
2) Where to find the particular configuration is precisely named
"omap4430sdp_config"?

I tried to grep "omap4460*" and "*gnueabi*" under the extracted (untared)
uboot folder, but nothing has been found....



Can anybody help please?


Best Regards

Hmm... Any reason you're not directly reading the Denx U-Boot site?

That's one way of doing it.

Any recent toolchain that generates ARM EABI code should be ok.

You have one in Ubuntu, btw (from Linaro), for instance.

Do you mean "how should I guess the configuration from the
device's name known to the general public"? If so, the answer is "by
Googling". There is no "general name to config" mapping that I know of.
But if I understand correctly, you already know which config to build,
right?

I don't understand what you are looking for there. Can you explain what
your problem is, rather than what solutions you are trying?
