Hi I use ZRouter build system and make arm-boot image. I add to armv4 setting ZRouter. Also I make change to mov from bx instruction at this directory assembly code. secure/lib/libcrypto/arm/ contrib/compiler-rt/lib/builtins/arm/ I checked bx instruction at kernel and init binary. There is nothing. It's right armv4 binary. If dts have bad geom_flashmap infomation then hang up at pause() at vfs_mountroot.c. This time can't use break. I think nearly close...
