[U-Boot-Users] Uboot failed to run with little endian.
Hi, all: My situation is: Board: customized board based on dbau1550. Uboot: 1.1.4 Toolchain: ELDK 4.0 Flash Progrmmer: From Macraigor System LLC. When I compiled Uboot as big endian(CROSS_COMPILE=mips_4KC-), everything was OK, Uboot worked perfectly. But when I compiled Uboot as little endian(CROSS_COMPILE=mips_4KCle-), It didn't run. And I debugged it. If it was big endian, the first instruction at 0xBFC00000 was 0x1000000ff, and if it was little endian, the first instruction at 0xBFC0000000 was 0xff000010. Can anybody explain this for me, and why uboot failed to run? Thanks Ray.

ummm... You understand the difference between little endian and big endian?
