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

Using unknown device ping failed; host 172.16.52.20 is not alive

Could you please give me any pointers for this problem?

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

Check the source code and find out why ping reports an "unknown device".

Hi Wolfgang,

I solved the unknow device issue by enabling the CONFIG_ETHER_ON_FCC1 in my config. Will check the TX clock configuration. Currently getting the blow messages. It says using the FCC1 ETHERNET.

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?

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.

Hi Wolfgang,

I have taken the sources of u-boot for version 1.1.6. I don't see flat tree support enable for any Board based on mpc8260 (CONFIG_OF_FLAT_TREE)I checked for IDS8272,MPC8260ADS. Can you let me know is there support for Flat tree structure for 603e cores. Also I don't see ft_setup function for this process.

Regards, Smitha

U-Boot 1.1.6 is nearly five years old (29Oct2006). Please consider updating to a modern version.

Hi ,

Can you point me to the latest stable uboot sources.

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.

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?

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.
