Check which initializations are done in the BDI init sequence, and
check which of them are needed and missing in U-Boot.

Hi Wolfgang ,

On my target board with MPC8247 is interfaced with the BCM5221 chip. Iam
using FCC 1 of the processor. 
Had defined below in my board config file. Configured the BCM5221
control register with 0X3100. 
Had set environment variables ipaddr, serverip, ethaddr ,netmask. When I
execute the PING
Command I get the following error 

>ping 172.16.52.20

Check your clock routing.  Eventually you have misconfigured the Tx
clock.

Did you solve this "unknown device" issue?  THis must be done first.

Hi Wolfgang,
 
I solved the unknow device issue by enabling the CONFIG_ETHER_ON_FCC1 in

[U-Boot] Flat tree structure dts file

[smitha.vanga at wipro.com]

 
Hi,

I am trying to port WindRiver linux 2.6.21 on to mpc8247 custom board.
Does for mpc8260 core is there support for 
CONFIG_OF_FLAT_TREE . 
How do I supply the device tree structure to the kernel. Do I need to do
this in the u-boot?
If yes how do I do?

Thanks & Regards,

In the first step, you should update your Linux kenrel code base.
Version 2.6.21 is about 20 releases behind (more than 4 years).
It makes absolutely no sense to invest any efforts in such old code.
Please do your self (and us) a favour and grab the recent kernel code
instead.  Device Tree support will then just fall in place.

Best regards,

Wolfgang Denk

[U-Boot] Console bring up on WR linux kernel on mpc8247 board

Hi Wolfgang,

I am trying to bring up WR linux 2.6.38.2 on a custom target board based
on mpc8247, We are using SCC1 for the serial console. Have initialized
the scc node in the dts as below. Had set the bootargs as setenv

My serial console doesn't come up. Can you give any pointers to this
would be of great help. I am stuck here and there is a project release.

This has nothing to do with U-Boot, so you are off topic here.

But before reposting the same question on a Linux related mailing
list, please make sure to check your boot arguments.  I huess your
console device is not /dev/ttyCPM, but /dev/ttyCPM0 or /dev/ttyCPM1 or
similar.

Best regards,

U-Boot 1.1.6 is nearly five years old (29Oct2006).  Please consider

Start here: http://www.denx.de/wiki/U-Boot/WebHome

and from there you will find a pointer to the release schedule

http://www.denx.de/wiki/U-Boot/ReleaseCycle

eventually you will find your way to the git repo for u-boot.

[U-Boot] Bootm command

Hi Wolfgang,

I am trying to boot linux by using the bootm command. It fails when it
tries to compare the filesystem header with the IH_MAGIC  and fails and
gets reset. Could you let me know what should I need to change this
number. This in cmd_bootm.c file in do_bootm_linux () function. Below
are the logs.

You certainly have some very old stuff here. The load addr 0x1000000 and 
0xfe340000 seem quite far from each other. Maybe that's the case, you're loading 
the stuff from some strange place?

[U-Boot] Bootm command

[smitha.vanga at wipro.com]

 
Hi Mark,

I didn't understand what you mean to say. Actually I have built a cramfs
image and programmed the file system at the location 0xfe340000(this is
flash address where it is programmed) in the flash .
I loaded uImage kernel image at 0x1000000 this is my ram area address. I
have loaded .dtb at 0x2000000
In ram. I have set my bootargs as

setenv bootargs console=ttyS0,9600 root=/dev/mtdblock4 rootfstype=cramfs

Now I try to boot the kernel image loaded at 0x1000000 address. As per
the log messages I see that
Kernel gets uncompressed and loaded at 0x00000000 address. It starts
loading the file system and
Then tries to read the header from the loaction 0xfe340000 and compare
the IH_MAGIC with the hdr->ih_magic the it says Bad Magic Number and
gets reseted.

Below is the piece of code where it fails.


if (hdr->ih_magic  != IH_MAGIC) {
			printf ("Bad Magic Number\n");
			SHOW_BOOT_PROGRESS (-10);
      
		 /* 	do_reset (cmdtp, flag, argc, argv); */
        if(auto_boot)
		        do_reset (cmdtp, flag, argc, argv);  
        else  
		        return 1;
     
		}

Regards,
Smitha

[U-Boot] Bootm command

Dear smitha.vanga at wipro.com,

The bootm command expects as second argument the address of a U-Boot
image containing a ramdisk.  A U-Boot image gets created using the
"mkimage" command and is something fundamentally different from a file
system image (it can contain such a filesystem image as payload,
though - but this is obviously not what you want to do here).

I think you should define proper MTD partitions on your flash and
provide a proper /dwev/mtdblock? as root device to your Linux kernel.

Best regards,

Wolfgang Denk

Unfortunetely these are incomplete, as they don;t show the actual
error.

And this effectively prevents me to reply.  Sorry.

Yes, I can.

My suggestion is to read the FAQ.

Ideally _before_ posting.

Do saveenv on console and reboot, see if message disappears.
