[microblaze-uclinux] Porting of redhat linux on PPC processor for memec board !!! pls help

[Ujwal <ujwal.mailinglist@xxxxxxxxx>]

Hi John,

this link 
http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/uclinux_powerpc/#linuxppc-2
talks abt PowerPC linux . but i want to port redhat linux 2.4/2.6 kernel to powerpc on memec board.
but this link says.... 
"This IS NOT uClinux for the PowerPC - it's a regular Linux kernel (a
modified MontaVista 2.4 kernel), build inside the uClinux-dist
environment and toolset commonly used for uClinux environment"

i dont understand if this is used for uClinux or powerpc
separately????  How do i compile for powerpc when im in
uClinux-dist directory without using the uClinux kernel??


Hi,

I have to Port Redhat Linux with kernel 2.6.x/2.4.x to PowerPC on Memec
Board - fg456 with Virtex II Pro FPGA. I'm using 2.6 kernel at the
moment.

As far as my knowledge goes, porting redhat linux to ppc has not been done by any1.
Only Montavista linux 3.1/VxWorks can be ported to powerpc processor
and usually done to ML300/400 series boards. The reason for choosing
redhat is, its free OS.

I have done the following until now :( not able to do step 4 and step 6)

Step 1) peripheral selection : I have been using the Xilinx EDK
(Embedded Development Kit) version 6.3i with the ISE 6.3i for selecting
the various peripherals like Ethernet MAC, SDRAM, FLASH etc....
Step 2) making a Board Support package(BSP) for Memec : generating the board support
package , but generating it for montavista linuxv3.1 OS(this is the
only procedure available) . Also , i read somewhere that , it should be
done like that only.
Step 3) generating the system.bit file : after doing the step 1 and 2 ,
i generate the libraries 1st using "libgen" and then generate the
hardware(system.bit file) using "generate binary files" option.
Step 4) now i get some files regarding the peripherals of the memec board 
in the BSP. A file called x_paramters_ml300.h contains the peripheral addresses
of the memec board.
Step 5) Meanwhile, i have created a cross compilation toolchain for powerpc
using gcc3.4.1 and glibc ....and done that in the linux2.6.x.
Step 6) I have my linux sources in /usr/src/linux-2.6.9 directory.I
have to cross compile this kernel for powerpc, but the problem is that
somehow i have to
incorporate all the BSP packages in the linux kernel and make it know that
x_paramaters_ml300.h file contains the board peripheral addresses and that
the system should compile for this board.
Step 7) that should generate a zImage.elf file that would be suitable to 
download to the board.


Please give me info on the same if u know... especially Step 4 and Step 6.

Thanks and Regards,
Ujwal
