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

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

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

That's one way of doing it.

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?

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

For example, from B), there are a lot of toolchains, how do I know which one I should use?

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

2. Where to find the particular configuration is precisely named

"omap4430sdp_config"?

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

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

Can anybody help please?

Best Regards

Amicalement,
