Hi,
I should have written the infomation for u-boot's board configuration.
> (2) build u-boot(2010.03) by the (1)compiler.
I rewrite configuration file for 'qemu-mips':
u-boot-2010.03/board/qemu-mips/u-bool.lds
--[original]
/*
OUTPUT_FORMAT("elf32-bigmips", "elf32-bigmips", "elf32-bigmips")
*/
OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradbigmips")
--[new]
OUTPUT_FORMAT("elf32-bigmips", "elf32-bigmips", "elf32-bigmips")
/*
OUTPUT_FORMAT("elf32-tradbigmips", "elf32-tradbigmips", "elf32-tradbigmips")
*/
---
And I use 'qemu-mips' board configuration for building u-boot.
$ cd u-boot-2010.03
$ make qemu_mips_config
$ make all
( I get 'u-boot.bin' )
