Hi,
We are using ELDK 4.0 with U-boot-1.1.4 and Linux kernel 2.6.15
we have ported u-boot to our MPC7447a based VME SBC board, it is working
fine.
but now we have compiled Linux kernel for our board.
we have used u-boot mkimage utility to create image file, by using
following commmand
./tools/mkimage -A ppc -O linux -T kernel -a 00000000 -e 00000000 -n
"linux_svme7447a" -d
/opt/svme_bsp/ppc_74xx/usr/src/linux-2.6.15/arch/powerpc/zImage
/tftpboot/linux_svme7447a.img
once this image is created we are using tftpboot command to download and
bootm command to boot image here it is giving problem.
the error log is attached below.
