BAPI = BestComm Application Programming Interface, i. e. the code in
arch/ppc/5xxx_io/bestcomm/

There are three ways to get something done:
        (1) Do it yourself.
        (2) Hire someone to do it for you.
        (3) Forbid your kids to do it.

Hi David,

   I have never done patch (I am a kid, help me grow
:-). the directories look a bit different to me as
compared that in the patch. PWD gives me this

nuguru@SW-server:~/linux_2_4_21_5200/arch/ppc$ pwd
/home/nuguru/linux_2_4_21_5200/arch/ppc

nuguru@SW-server:~/linux_2_4_21_5200/arch/ppc$ ls
4xx_io   8xx_io  Makefile  boot       configs   
iSeries  lib       mgt_io  platforms    xmon
8260_io  CVS     amiga     config.in  defconfig 
kernel   math-emu  mm      vmlinux.lds
nuguru@SW-server:~/linux_2_4_21_5200/arch/ppc$


I dont see the 5xxx_io .. but everything in mgt_io has
output files 

nuguru@SW-server:~/linux_2_4_21_5200/arch/ppc/mgt_io$
ls
CVS        Makefile  fec.c  fec.o     psc.c 
sc_task.impl.S  sdma.o
Config.in  bestcomm  fec.h  mgt_io.o  psc.o  sdma.c   
      sdma_5100.c

the bestcomm directory doesnt have "capi" folder in ..

Attaching the bestcomm folder on my system, and daring
to ask to send me a patch for this one. 

If you feel that it will take more of your time can
you please suggest me some other options :-)

yes David i am using rev.B1 and I tried setting the

I tried also ur second suggestion trying to boot
through ramdisk, with rootfilesystem in
ramdisk.image.gz and building kernel in pImage both in
Compact Flash.

It is working fine ( I have no idea of the
configuration and what args are passed by U_BOOt to
kernel) .. does this mean that there is problem with
root filesystem on my remote computer or does this
mean there could be a problem connecting to the remote
computer (Probably problem with BESTCOM as pointed by
Wolfgang Denk) ?????

I want to have the root filesystem on the remote
computer instead on ramdisk because i need to add
applications into the root filesystem in runtime.

boot failure help needed

[Susheel Raj]

Hi all,

 I am using freescale mpc5200B on the board. I have a
tftp-server on my machine and connect to the board
through this server. 
  the Kernel and the root file system are ion my
desktop PC in the directory /tftpboot/
  kernel --->  /tftpboot/pImage
  root fs ---> /tftpboot/rootfs/

We have U_Boot for booting system and it fetches the
kernel from the server (that is my esktop PC) through
the ETHERNET connection. rootfile systems stays here
in the server ,

ls command shows  like this in /tftpboot/rootfs/
[root@localhost rootfs]# ls

bin  build_dir  deep_sleep  dev  etc  lib  mnt  opt 
proc  sbin  tmp  usr  var

console interface is console=ttyS0 on to the board

now the problem is that if i use MPC5200 Rev A then
the kernel boots without any problem and gets into the
command 

but when i am using MPC5200 Rev B it shows like this

You need BAPI v2.2 for the Rev. B processors.
