Reading the webpage linked it seems like that thing has a hardware FPU, |
| 22 |
so you can use your suggestion. However, arm-unknown-linux-gnu will |
| 23 |
procude ARM OABI code. You might also want to try |
| 24 |
|
| 25 |
arm-unknown-linux-gnueabi |
| 26 |
|
| 27 |
to use ARM EABI instead. See |
| 28 |

Furthermore according to |
| 33 |
http://www.arm.com/products/CPUs/ARM1136JF-S.html |
| 34 |
http://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/ARM-Options.html#ARM-Options |
| 35 |
|
| 36 |
I would use |
| 37 |
|
| 38 |
-march=armv6j -mtune=arm1136jf-s |
| 39 |
|
| 40 |
in the CFLAGS. |
| 41 |
|
| 42 |
Have fun! |
