Cross toolchain for ppc405 (virtex-4)

Cross toolchain for ppc405 (virtex-4)

[Mirek23]

Hi All,

I am using for some time the crosstool tool-chain (crosstool-0.43) for the
ppc405 of my virtex-4.
It seems to be that the crosstool was not updated for awhile but the glibc
and gcc compiler has changed a bit meanwhile.

The latest working configuration to build the toolchain for ppc405 is
gcc-4.1.0-glibc-2.3.6.dat
Does any body has tried to adapt the crosstools to use for example glibc 2.7
?

Another alternative would be to use another tool than crosstool. Could
somebody recommend something which can refer to newer version of gcc and
glibc .

Best Regards

Miroslaw Dach

Hi Miroslaw,

I'm not sure on what version of gcc and glibc it's using, but I have been using ELDK 4.1 from denx.com. There are newer versions.

Thanks,
John

Hi Jonh,

If I use ml403 (with PPC 405) Did i change the predefined compiler flags
for ppc_4xx? The default value is -mcpu=403.

I don't know, I'm not familiar with what you are doing and it's not clear from the message.

I'm sorry.

I want build kernel linux 2.6 for ml403. 
Did I have to change the predefined compiler flags for ppc_4xx? The default
value is -mcpu=403.

Re: Cross toolchain for ppc405 (virtex-4)

[David H. Lynch Jr.]

I am not sure if this answers your question but to build a 2.6 Linux
kernel using the buildroot uclibc ppc cross compiler you would issue the
following make command

make ARCH=ppc CROSS_COMPILE=powerpc-linux-uclibc-

If you were using the crosstools compiler rather than buildroot, the
CROSS_COMPILE value would change.
For older version of GCC it might require a full path to the crosscompiler.

If you are building a BSP in the powerpc tree use ARCH=powerpc

I am fairly certain that when you are building a Linux kernel it is
irrelevant whether you use a glibc or uclibc or ... compiler.
The kernel is not going to link against any standard C library, those
library functions the kernel uses must be coded in the kernel.

However, when you are cross compiling applications for your target it is
a good idea to stick to the same standard C library and associated cross
compiler.

The more recent ELDK 4.2 supports 405s and its crosstoolchain uses
binutils 2.17.50.0.12, gcc 4.2.2, glibc 2.6 and gdb 6.7.
