My system is a MPC8275 based PQ2FADS-board. U-Boot 1.0.2 is running on it. Toolchain ELDK 3.0.
The base board in the kernel menuconfig is the MPC8260ADS. I read in the user manuals of both MPC8260ADS and PQ2FADS. Their base adresses of immr and bcsr are identical.
The FCC MDIO support was changed for the PQ2board.
Where are the problems?
TEA signal of my ppc ?? I've greped the traps.c in arch/ppc/kernel of the denx linuxppc_devel kerneltree. RAM Problems ??


What do you know about this message ??

Thanks in advance

Marco

kernel hangs

[ganesh.patwardhan]

Hi,

         I have compiled linux-2.6.25 for MPC837X processor and generated "vmlinux.bin" image and then
          integrated this image with "rootfs" to generate "uSystem".(This is done using mkimage utility)
         Then downloaded this uSystem image in flash and tried to boot linux from u-boot. but linux hangs  at
         "Transferring control to Linux (at address 00000000)"
         .....please refer log below.

         If you have any idea due to what this problem may occur, please help me.
