Building a Kernel for the AMCC PPC440EP Bamboo Board

Building a Kernel for the AMCC PPC440EP Bamboo Board

[Zeighami, Roy]

Hello...

I am trying to build a kernel image for the AMCC Bamboo PPC440EP board.

My colleague downloaded a preview kit from MontaVista and that worked.

However, I am trying to build a toolchain using crosstool and create a
2.6.x kernel image.  However, when I type:

"make ARCH=3Dppc CROSS_COMPILE=3Dpowerpc-440-linux-gnu- menuconfig"

When I select 44x as the CPU type, I don't see "Bamboo" under machine
type. =20

Also, I tried building a 2.6.8 kernel image  with Ebony but I can't get
a successful build.

I get the following errors:

drivers/built-in.o(.text+0x3c7ec): In function
`floppy_release_irq_and_dma':
: undefined reference to `free_dma'
drivers/built-in.o(.text+0x3dc14): In function
`floppy_grab_irq_and_dma':
: undefined reference to `request_dma'
drivers/built-in.o(.text+0x3dddc): In function
`floppy_grab_irq_and_dma':
: undefined reference to `free_dma'
make: *** [.tmp_vmlinux1] Error 1

However, the crosstool web site says that the following combo should
build: gcc-3.4.2, glibc-2.3.3, binutils-2.15, linux-2.6.8

Any suggestions?

Also, if the kernel source provided by Monta Vista is some special
branch that isn't merged to kernel.org, does anyone know how to get the
latest source from Monta Vista?

Is one of these the version that I should be getting?

This won't work, as Bamboo BSP stuff is currently not added.

try to use ebony_defconfig

guess you should ask AMCC or MontaVista directly - or extract the 
stuff from the sources you already got from the preview kit.

Ciao,

Hi,
as I know there is no public available kernel tree with Bamboo support, =
you have to implement it yourself if you need it right now or just wait.
Please correct me if I'm wrong.

Best regards,

Correct.

Doesn't work, neither does ocotea.  Both are able to display "TUX!" on
the dot-matrix display, but panic before writing any serial output.

/me has one of these beauties as well and will try to hack up support
for it.  If anyone has patches or suggestions, help is always
appreciated.

Could not confirm that so far! Ebony and Ocotea are working out of the
box, using these defconfig files! (pristine kernel 2.6.11)

With PIBS and on a bamboo?  If I was just too stupid and made some
silly mistake, that would be great news.

I'm in doubt about having red my post carefully! I talked about EBONY
and OCOTEA, ebony with OPENBIOS, ocotea with PIBS!!!! NO BAMBOO!!!!!

Impossible. You need a 440EP/Bamboo specific port. Memory map is
completely different on 440EP.  For discussion sake, note that
440GP/GX are very similar parts with respect to memory map and
peripherals, then 440SP and 440EP each have very different layouts.

FWIW, there's somebody well into a 2.6 440EP port, dunno what the
ETA on submitting the code is.

Right.

Would be nice to get either somebody's name or the preliminary code.
I don't care about crashes too much (can't be worse than not working
at all) and am willing to help.  If neither is realistic - heck, we
need to get familiar with the cpu anyway, so there is no reason not to
race for submission. ;)
