Building XDev To Build U-Boot #164

Closed ThothK closed 7 years ago

ThothK commented 7 years ago

Hello People,

I have been having problems with building the Cross Development tools.

Some of the variants I tried include:

With one exception stddef.h is not found. ===> lib/libc++ (obj,all,install) /usr/obj/armv6-freebsd/usr/src/lib/libc++ created for /usr/src/lib/libc++ ... In file included from /usr/src/lib/libc++/../../contrib/libc++/src/algorithm.cpp:10: In file included from /usr/src/lib/libc++/../../contrib/libc++/include/algorithm:624: In file included from /usr/src/lib/libc++/../../contrib/libc++/include/initializer_list:47: /usr/src/lib/libc++/../../contrib/libc++/include/cstddef:43:15: fatal error: 'stddef.h' file not found

include_next

The one exception I mentioned was a linker error. However, the above is what I received most of the time.

I have tried with FreeBSD versions 10.0, 10.3, and 11.0.1. All fresh installs as Virtual Machines.

If I understand correctly, U-Boot has to be compiled with gcc and we need an ARM 'version' of gcc to compile U-Boot for our purposes. However, I seem to be unable to build the Cross Development tools.

This seems to be a FreeBSD problem and I should let someone know, but I do not know who nor how.

I would appreciate help and / or suggestions. I really would like to be able to compile U-Boot in the FreeBSD VM so I can try pushing it to a device.

Hi,

IIRC xdev is deprecated. Why are you using it? What ARM board are you building it for? We have ports for a lot of them that you should use instead if possible.

Most Crochet boards now use U-Boot from ports, so Crochet should no longer need to compile U-Boot at all. In particular, xdev should not be needed.

Hi Brad,

I did not realize that XDev was deprecated. I thought it was no longer required. Even still, I should have been able to build the tools with FreeBSD 10.3, right?

I was trying to get the Cross Compile tools to build U-Boot. This is the only way I know how on FreeBSD.

I am building it for an NVidia TK1 (ARM Cortex-A15) in an NVidia Shield K1 tablet.

I did not see Jetson or any of the other NVidia products in the boards Crochet boards list. Did I miss it? I will slap the back of my head if you did, but still. Is there someplace other than the supported boards list I should be looking?

I have the U-Boot source that NVidia is using for their Ubuntu distribution. Since I know that works, I thought I I should determine how to build it, find out the changes Crochet makes (used to make), implement those, and build it again with the Crochet changes or whatever is appropriate.

Hi Tim,

Do you mean U-Boot from FreeBSD Ports? Should this be in my ports tree in the FreeBSD VM? If so, I did not make that connection after reading /freebsd/crochet/blob/master/lib/uboot.sh or anything else.

You have answered a different question I have been trying to find the answer for. That is that Crochet does not need to compile U-Boot for the most part.

Hi,

Since there is a different path now, does anyone have any suggestions on how I should compile U-Boot on FreeBSD? Unless I can find a FreeBSD ready version of U-Boot NVidia is using for their Ubuntu distro, I think I need to learn how to build it on FreeBSD.

If there is something obvious that I am missing or a different tack I should take, please let me know. The objective is to get FreeBSD running on the NVidia Shield K1 tablet.

Yes.

Yes.

That code is legacy code and should probably be removed. At the time it was written, the ports tree did not have working cross-compilers for ARM, so xdev was the best available option. Since then, the ports tree now has solid cross-compilers available, xdev is no longer supported, and there are U-Boot ports for the most popular boards.

suggestions on how I should compile U-Boot on FreeBSD?

Start by copying one of the existing U-Boot ports. They use cross-compiler tools from ports, which are stable and supported now. Best of all, if you can get a new port working, you can submit it to the FreeBSD ports collection for others to use.

Hi Tim,

Thank you. I am going to close this issue since building the cross compiler tools is no longer part of the process.

I intend on submitting whatever I can get working that someone has not already done. If this effort pays off and I can get the company I work for to switch to FreeBSD for the project, and we make improvements or whatever, I intend on pushing to submit that as well.

This just reminds me about how much I have to learn about FreeBSD.

Great! We would welcome your contributions to getting FreeBSD to work on another ARM device. It can be difficult to get drivers and things written, but I wish you luck!

brd commented 7 years ago

Oh, I forgot to mention you should email the freebsd-arm list and ask if anyone else has that hardware.
