How large of an initial TLB are you setting up for all of this in your simple bootloader? >the problem that i face is kernel crashes in different places while booting >for different linux images, but always mentioned that >TASK = 'swapper' > >Can anyone tell what would be the problem..? I won't quote the file itself since your email is terribly word-wrapped, but the #address-cells = <1> in the root node looks incorrect for a 440 based CPU. It should be 2, as 440 does 36-bit addressing. Similarly for the PLB node. You would need to fix the memory reg property for this. The CPU node should probably have #size-cells = <0>, though I don't think that matters much. The serial port appears to be at an odd address for a 440 based SoC, but I have no idea if that is correct or not. Outside of those issues, I can't think of anything off the top of my head that would cause the panic you are seeing. josh _______________________________________________ Linuxppc-dev mailing list [email protected] https://lists.ozlabs.org/listinfo/linuxppc-dev
