[linuxsh-dev] Compiling Linux kernel on ST407750 Overdrive board

[<kl...@fu...>]

Hi,

I hope this is the correct mailinglist for this kind of question.

We are currently working on porting the Linux kernel to a ST407750 =
Overdrive board. We have found the document =
(http://linuxsh.sourceforge.net/docs/building-source.php3) describing =
how to build the kernel for SH processors. We do, though, have some =
problems.

We use the following kernel configuration:

CONFIG_SH_STB1_OVERDRIVE=3Dy
CONFIG_CPU_SUBTYPE_SH7750=3Dy
CONFIG_CPU_SH4=3Dy

along with default configuration. The problem seems to be that the gcc =
version does not support the -m4-nofpu option. We have tried to change =
this in kernel/arch/sh/Makefile:
diff Makefile_org Makefile_changed
49,50c49,50
< CFLAGS                +=3D -m4-nofpu
< AFLAGS                +=3D -m4-nofpu
---
> CFLAGS                +=3D -m4
> AFLAGS                +=3D -m4

but this give rise to other problems.

As we need the Overdrive board as a reference for other ports, we would =
like to know if there is a "safe/easy" way to make the kernel work on =
the Overdrive board. We also experience problems in getting the sh-ipl+g =
to compile. Which version of gcc, binutils and the kernel should we use =
and where should we obtain them ? Is the above mentioned document still =
up-to-date?


thank you,
