Hi all,

I am trying to boot TQM5200 with linux 2.6 kernel. i am using latest version of linux and u-boot from denx. And compiled with ELDK4.1 

i use dtc compiler with following command:
dtc -O dtb -o tqm5200.dtb -b 0 tqm5200.dts

Booting process gives following error and reset the board.

WARNING: could not create /chosen FDT_ERR_NOSPACE.
ERROR: /chosen node create failed - must RESET the board to recover.

Regards.

The following switches to dtc taken from
http://www.denx.de/wiki/UBoot/UBootFdtInfo work for me:

dtc -b 0 -V 17 -R 4 -S 0x3000 -I dts -O dtb -f tqm5200.dts > tqm5200.dtb

You might want to try them out, especially the "-S 0x3000".

Bartlomiej

-V 17 is the current default, btw.

Latest U-boot need a chosen node in your DTS  file, So u need to add a
chosen node in your DTS file.

Take mpc8272ads for example: in its DTS, has the following:

        chosen {
                name = "chosen";
                linux,platform = <0>;
                interrupt-controller = <&Cpm_pic>;
        };


BRs,

It does not.

Please don't use that file as an example. :-)
