I'm sorry, looks like I mentioned wrong 2 pieces. By softfloat I mean gcc flag |
| 18 |
-msoftfp and there should be -mcpu, not -mach. Basically, my 3 systems are based |
| 19 |
on |
| 20 |
1) arm1136 |
| 21 |
2) arm1176jzf with CFLAGS+=-softfp |
| 22 |
3) arm1176jzf without using FPU |
| 23 |
I think they could be built with same cross-toolchain. |
