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

Thanks in advance.
