[U-Boot-Users] Single ARM Toolchain?
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.) - Dan

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.

2. Same problem as #1 BINUTILS_DIR=binutils-2.11.2 BINUTILS_URL=ftp://ftp.gnu.org/pub/gnu/binutils GCC_DIR=gcc-2.95.3 GLIBC_DIR=glibc-2.2.5 LINUX_DIR=linux-2.4.3 GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.2.5
3. The kernel refuses to try to compile with GCC 3.2.x
4. Compiles Linux but has an error with U-Boot

I see. Yes, this has been reported before.

I will try this. Hopefully there are build instructions for the tools.
Of course (or just install the binaries).
