(1) The Ubuntu cross toolchain does not support compiling for pre-v7 targets -- it doesn't have a v4t-only libgcc, only a v7 one, so when that is linked into your binary then it will not work on a v4t target. You'll need to find a different cross compiler which does support targeting v4T. (Maybe the debian or codesourcery ones??) (2) QEMU doesn't support emulating the ARM920T. -- PMM
