Hi again
In meantime I have built gnutools arround GCC 4.6.0:
gcc-4.6.0
newlib-1.19.0
binutils-2.21.51 (+ OS patch, see note below)
gdb-7.2
First tests are encouraging, I was able to get "Hello world" with both
HAL and devs serial driver.
Note regarding binutils-2.21.51:
> -. binutils-2.21.51 (patched snaphot with OS
> support for cortex-m4)
I don't quite figure out whether you mean that you downloaded
binutils-2.21.51 already patched or you have applied the patch. I
downloaded binutils-2.21.51 today and it is didn't have the OS patch,
(Btw it seem to have been committed yesterday):
http://sourceware.org/bugzilla/show_bug.cgi?id=12296
However gcc-4.6.0 works for Cortex-M4, or at least for Kinetis - with
both -mcpu=cortex-m4 and -mcpu=cortex-m3.
I am looking forward to your tests.
Regards
Ilija
