Hi,

I am using u-Boot 2013.04 to boot an AT91SAM9263-based board. I use a GCC/uClibc cross compiler which I updated to use GCC-4.7.3 and came across a strange problem (see attached log files).

uBoot_GCC-4.7.1.log - Bootstrap built with GCC-4.7.3 - uBoot built with cross-compiler based on GCC-4.7.1 - Kernel built with GCC-4.7.3

uBoot_GCC-4.7.3a.log - Bootstrap built with GCC-4.7.3 - uBoot is built with GCC-4.7.3 and throws the hash table error shown - Kernel built with GCC-4.7.3

uBoot_GCC-4.7.3b.log - Bootstrap built with GCC-4.7.3 - uBoot is built with GCC-4.7.3 and halts after the "using default environment" message shown - Kernel built with GCC-4.7.3

The uBoot source code is the same for all builds. The hash-tables problem seems to have occurred in the past with uBoot-2010.12. I tested the builds on 10 different boards and 8 resulted in the uBoot_GCC-4.7.3b log while 2 resulted in the uBoot_GCC-4.7.3a log. All 10 boards worked correctly when uBoot was built with the GCC-4.7.1 based cross compiler.

Initially I assumed that the fault was with the compiler but both the bootstrap and the kernel compile and run fine, only uBoot fails.

I did some further investigation and discovered that when the GCC/uClibc cross-compiler is built with the following sources, uBoot builds and runs correctly.

binutils-2.22 gcc-4.7.1 gmp-5.0.5 linux-3.6.11 mpc-1.0 mpfr-3.1.1 uClibc-0.9.33.2

When the GCC/uClibc cross-compiler is built with the following sources, uBoot builds without error but does not run.

binutils-2.23 gcc-4.7.2 gmp-5.0.5 linux-3.6.11 mpc-1.0.1 mpfr-3.1.1 uClibc-0.9.33.2

I'm continuing to narrow this down but I was wondering if anyone has already come across this and could help me resolve it more quickly.

Cheers,

Tom
