Problems compiling Linux for MPC8272ADS

Problems compiling Linux for MPC8272ADS

[Manil Gaouar]

Hi there,

I am trying to compile the latest Linux from the git repos: git clone
git://www.denx.de/git/linux-2.6-denx.git linux-2.6-denx, I checked out
the code a few weeks ago and was able to build my uImage no problems. I
did a git pull this morning and I can not compile anymore, here is the
error message I have:

  BOOTCC  arch/powerpc/boot/ps3.o
  BOOTCC  arch/powerpc/boot/treeboot-bamboo.o
  BOOTCC  arch/powerpc/boot/cuboot-sequoia.o
  BOOTCC  arch/powerpc/boot/treeboot-walnut.o
{standard input}: Assembler messages:
{standard input}:184: Error: Unrecognized opcode: `mfdcr'
{standard input}:185: Error: Unrecognized opcode: `mfdcr'

{standard input}:217: Error: Unrecognized opcode: `mtdcr'
make[1]: *** [arch/powerpc/boot/treeboot-walnut.o] Error 1
make: *** [uImage] Error 2

here are the commands I am using:

make mrproper
make ARCH=3Dpowerpc CROSS_COMPILE=3Dppc_6xx- mpc8272_ads_defconfig
make ARCH=3Dpowerpc CROSS_COMPILE=3Dppc_6xx- uImage

Do you have any ideas, or I should check out the 2.6.22 stable release
instead and try again???

Thx

I added this to my boot/Makefile near the other mcpu=440 lines.  I
believe there may be a fix coming?

$(obj)/treeboot-walnut.o: BOOTCFLAGS += -mcpu=440
$(obj)/4xx.o: BOOTCFLAGS += -mcpu=440
$(obj)/ebony.o: BOOTCFLAGS += -mcpu=440

Apply this:


    [POWERPC] 4xx: Fix Walnut wrapper compile errors
    
    Pass the appropriate -mcpu flag to the treeboot-walnut.o object to prevent
    some toolchains from erroring out with unknown opcodes

I believe there is.

It should be -mcpu=405 for Walnut, though.
