Re: MPC5200b MMC over SPI into PSC6

Hello,

in uboot i have setting the bootargs variable:

=> bootargs debug console=ttyPSC0,115200 root=/dev/ram
=> saveenv

If I'm not wrong, the right sequence of commands should be the following:

$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
.. [customizations]...
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- cuImage.lite5200b

and this is the output:
..
 CHK     include/linux/version.h
 CHK     include/linux/utsrelease.h
 CALL    scripts/checksyscalls.sh
 CHK     include/linux/compile.h
 CALL    arch/powerpc/kernel/systbl_chk.sh
 WRAP    arch/powerpc/boot/cuImage.lite5200b

At this point I've loaded the cuImage and rootfs.uimage on the board:

=> usb start
=> usb scan
=> fatload usb 0 0x03000000 cuImage.lite5200b
=> fatload usb 0 0x04000000 rootfs.uimage
=> bootm 0x03000000 0x04000000

but it still hangs after this:

Where is the problem? The problem is the my rootfs.uimage?

Do you have any idea?
Best regards,

Thanks for the patches, now some more rows are printed after RamDisk loading:

Doesn't look like you are passing a kernel parameters line.  The
kernel probably is booting, but doesn't know where to output the
console.  Try adding "console=ttyPSC0,115200".
