[U-Boot-Users] Single ARM Toolchain?

[U-Boot-Users] Single ARM Toolchain?

[Allen Curtis]

I have created several versions of ARM cross-compiler
toolchains but have not discovered a configuration
that works with both "u-boot" and Linux 2.6.

Using crosstool-0.27:
GCC 2.95.3, BINUTILS 2.14.90.0.8, GLIBC 2.2.5 - builds
the Linux kernel but not U-Boot

GCC 2.95.3, BINUTILS 2.11.2, GLIBC 2.1.3 - builds
U-Boot but not 2.6 Linux kernel (.incbin support)

The newest GCC I can build on my system is 3.2 since
my host compiler is 2.96.

I have searched the archives and found that this is a
common question. Unfortunately I did not find a
definitive answer.

TIA

Can you post the errors?
(btw, crosstool-0.27 had some arm issues,
and crosstool-0.28-rc13 has the vfp printf patch,
but I'm not sure those matter for this.)

Ummm... I've tried only few, but all seemed to work.

What is the problem when building U-Boot? Which version of U-Boot?

Use the ELDK?

Version 1.1.1. From other postings on u-boot it
appears that the issue is soft float support...

I will try this. Hopefully there are build
instructions for the tools.

*** Copy of an email sent to Dan Kegel regarding this
issue. The U-Boot compilation errors are below.

1. This will not compile Linux 2.6 because the
binutils are too old. Need support for .incbin.

BINUTILS_DIR=binutils-2.11.2
BINUTILS_URL=ftp://ftp.gnu.org/pub/gnu/binutils

2. Same problem as #1

3. The kernel refuses to try to compile with GCC
3.2.x

4. Compiles Linux but has an error with U-Boot

5. This appears to compile both but we are using 2.4

cross compiler fails.

I see. Yes, this has been reported before.

Of course (or just install the binaries).
