RE: ep8260 board linux port

Allen,

quoted

  I am trying to port linux 2.4.22 onto ep8260 board. (256 MB RAM on
6xx
bus/ 32 MB Flash) using tools and source code from denx webisite.
  I was able to port u-boot and trying to boot linux now.
  i couldn't find any specific files to this board in the platform
directory
although est8260.h file has the basic bd structure. the problem i am
facing
is the processor loops in serial_console_write/ timer interrupt
handler. i
made sure that i am passing the baudrate proeprly by looking

at the bd

structure while passing teh control to start_kernel function.

How are you creating your boot image. If you are following the u-boot
directions then you don't need any board specific support in the
kernel. If you are trying to boot zImage, then you have more work to
do.

Do you mean zImage.embedded? I have been using make_image utility from
uboot and using image arch/ppc/boot/images/vmlinux.gz to create image that
uboot downloads via tftp.

  My console does display everything properly running u-boot

but once

the
control goes to linux don't see anything on the console.

Did you happen to customize the BAUD rate information for u-boot or
Linux?  The u-boot default is 115K, Linux default is 9600.

Another thing that I have run into is the clock divider configuration
by u-boot. Try changing your minicom baud rate up or down by
4X and see
if you see anything then.

I tried changing the baud rates didn't make any difference. If I attach
the BDI it is looping in serial_console_write. I did verify that clock
rate is getting passed from uboot to kernel correctly. In uboot I am
not setting the variable clock_in_mhz.

Doea anybody have .config file for EP8260 that I can use?
