Newbie on embedded linux on PPC: error: cannot find boot.o

Newbie on embedded linux on PPC: error: cannot find boot.o

[Thomas Gerlach]

hi folks,


my name is thomas trying to make embedded linux run on a powerpc, but we've got special boards here, although we use a xilinx virtex4 fpga...

as you said in the nabble-thread (see subject), i set up edk9.1 software platform settings und ran libgen to get the xparameters* files. i copied those bsp files into the kernel tree (i use your kernel linux-2.6-virtex from git.secretlabs.ca/git). after configuring the kernel settigs, i try

$ make ARCH=ppc CROSS_COMPILE=powerpc-eabi-

what i get is the following output:

>   CHK     include/linux/version.h
>   CHK     include/linux/utsrelease.h
>   CALL    scripts/checksyscalls.sh
>   CHK     include/linux/compile.h
>   LD      init/mounts.o
> powerpc-eabi-ld: cannot find boot.o
> make[1]: *** [init/mounts.o] Error 1
> make: *** [init] Error 2

so, i searched for boot.o (it exists) and even copied it into several dirs of the linux kernel tree (where i thought i would make sense), but the problem still remains.

googling results in

and this, too, doesn't take me further in solving the problem.

i hope you can help me.

many thanks in advance,

Flash on ep8248e standard motherboards

[Bennett, Alan]

Hello;
We have a custom board based on the ep8248e design from Embedded Planet
and I'm trying to use something other than codewarrior to flash u-boot
srec's=20

I'm not sure where the problem is, but I'm unable to flash the
u-boot.srec onto the Embedded Planet board (using the BDI2000), let
alone our custom board.
   1. Embedded Planet ep8248E
        64 MB SDRAM
        64 MB Flash (x2 Am29LV256M)
   2. Custom
       128 MB SDRAM
       128 MB Flash (X2 Spansion S29GL512N)

NOTE: CW successfully flashes both parts, but then again, it's CW.


BDI 2000 Config File:
  ;  initialize - FLASH BR0 & OR0 (64 Mbyte)
  ;*******************************************
  WM32	0xf0010100 	0xfc001801
  WM32 	0xf0010104 	0xfc0008c2
  [FLASH]
  CHIPTYPE    MIRRORX16
  CHIPSIZE    0x2000000
  BUSWIDTH    16

I then attempt to unlock/erase/program
Check for Sanity (NOTE: using BDI 2000 PROMPT)
  md 0xf0010100 2
  f0010100 : 0xf8001801  - 134211583  ....
  f0010104 : 0xf80008b2  - 134215502  ....
  md 0xfff00000 2
  fff00000 : 0x10101010    269488144  ....
  fff00004 : 0x10101010    269488144  ....
All looks good.  (10101010 is the existing planet core header)

TRY TO UNLOCK
  unlock 0xfff00000 1000
  Unlocking flash at 0xfff00000
  # Invalid parameter for flash programming

TRY TO ERASE
  erase 0xfff00000 UNLOCK 1000
  Erasing flash at 0xfff00000
  # Erasing flash memory failed
BUT
  erase 0xffff0000 UNLOCK 1000
  Erasing flash at 0xffff0000
  Erasing flash passed
HOWEVER
  mm 0xffff0000 0xdeadbeef
  md 0xffff0000 1
  ffff0000 : 0xffffffff
SO it doesn't seem to allow write access afterall...

Is there anyone that has a BDI 2000 config file for flashing the ep8248e
motherboard the 8MB Flash Version (64 MB flash version)=20

Thanks
-Alan

Hi Thomas,

Xilinx is building the tools in the EDK to work with VxWorks and for Standalone systems. In order to compile a Linux kernel you need to get a toolchain from one of the Third Party vendors, such as MontaVista. They have the correct linker scripts for building a kernel.

Cheers,
   Wolfgang

hi,
thank you much for this hint, i'll try it. this was the last thing i 
thought of... ;)

kepp on cross-compiling, :)

You can also build a ppc405 toolchain using Crosstool, and it works
fine..

You should be using a Linux cross compiler, not powerpc-eabi-.  The
Xilinx cross compiler will not work to compile Linux kernels.

You can build yourself a cross compiler using 'crosstool':
http://www.kegel.org/crosstool.

Alternately, you can download ELDK:

hi,
thank you much for this hint. this was the last thing i thought of... ;)

so long, keep on cross-compiling! :)
