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:
- 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.
- 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,
