mpc8349-mITX DTB load failure
Hello All, I am trying to boot the mpc8349-mITX board with Compact flash support, and am unable to boot the Linux kernel. Here is the pertinant versioning information: DTC 1.2.0-rc2-g17773b0e U-Boot 1.3.4-rc1-00012-g1953d12 Linux-2.6.26-05752-g93ded9b I've built the DTB using the following two commands - neither change the error I get during boot-up. $ ../dtc/dtc -b 0 -I dts -O dtb -R 4 -S 0x3000 -o /tftproot/ssparks/itx/cf2/itx.dtb -V 17 arch/powerpc/boot/dts/mpc8349emitx.dts $ ../dtc/dtc -I dts -O dtb -o /tftproot/ssparks/itx/cf2/itx2.dtb arch/powerpc/boot/dts/mpc8349emitx.dts Can anyone shed any light onto what I am doing to cause the following error? I haven't been able to find this error message in the mailing list or by asking google... ## Booting kernel from Legacy Image at 01001000 ...

No luck there, either. I ran into a issue with space a year ago, and was getting the FDT_ERR_NOSPACE error until I added the -S 0x3000 option. This looks like something completely different.

Does your dts source file already have a chosen node? There had been an issue where u-boot cacks if chosen was pre-created. g. ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

Nope, there is no reference to chosen in the dts --Sam ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

Can you try different load addresses, preferably with the two images at least 0x3000 bytes apart?
