[Buildroot] MIPS Crosstoolchain for MIPS24K with dsp amd 24k compiler options

[sathesh babu]

Hi, 
   
  I would like to build cross toolchain for MIPS24K processor with "-mdsp" and
   "-m24k" compile flag options for linux-2.6.18.8 kernel.
   
  I tried with below combinations of
  - GCC-4.2.1,GCC-4.0.1, GCC-4.1.0
  - binutils-2.15, binutil-2.17,binutil-2.18 
  -  uClibc-0.9.27 
  but i couldn't succeed any of the above combinations.
   
  I checked the mailing list and it is mentioned that GCC-4.2.x version of gcc has problems.
   
  Could you please guide me the, the exact versions of
   - GCC 
   - binutils
   - ucLibc
  to be used to build toolchain with "-mdsp" and "-m24k" compiler options for linux-2.6.18.8 kernel version.
   
  Thanks. 
   
  Regards,
  Sathesh

Try gcc-4.2.0 binutils-2.17-50 and uClibc -0.9.28.

Alternatively you can download a timesys toolchain from 
ftp://ftp.mips.com/pub/tools/software/timesys/toolchains/LDE-3.00.00/


If you are just building a kernel and nothing else you can get away with 
the 'bare' gcc here: ftp://ftp.mips.com/pub/tools/software/sde-for-linux/
