Build process is complete, but U-Boot does not work correctly. Because of linking the wrong version libgcc.a, which contains armv5 instruction such that arm core raises a undefined instruction exception then code hanged. > > >> > NAK.

I found another way to solve this issue. In arch/arm/cpu/arm920t/config.mk, change this line from PLATFORM_CPPFLAGS += -march=armv4 to PLATFORM_CPPFLAGS += -march=armv4t Then everything goes well. This solution won't make any modification on top level Makefile. But I don't know exactly that the solution will incur other side effect or not? BTW, If this solution is the right thing to do, shall I issue another patch?
