Hi,
I have a custom board, based on Freescale M5271EVB, use codesourcery
toolchains 2010.09-41.
Board code are almost same as the evb board:
- include/configs/M5271EVB.h
- board/freescale/m5271evb/
- arch/m68k/cpu/mcf52x2/
$ export CROSS_COMPILE=...
$ make M5271EVB_config
$ make
1. I got linking error in version 2010-09 and later: libgcc.o not found.
It is just fine in 2010-06, which use libgcc.a from the toolchains.
How to change back the build rules to link to libgcc.a in the latest
version of u-boot?
2. I have u-boot 2010-06 booted on my board. Everything seems ok
(uart, ethernet, ram, flash,...)
* 0x00000000 - 0x00FFFFFF SDRAM 16M
* 0x20000000 - 0x2000FFFF Int SRAM 64k
* 0xFF800000 - 0xFFFFFFFF Flash 8M

I have no idea why the command i just typed is in this address.
The problem seems u-boot memory is overwritten, But I think it must be
in the preserved range (> 00f8bf96) after relocating.
Thanks in advance.
