Need help ragarding MPC8360 Kernel bootup failure

Hello all,

I need help regarding the bootup of linux on MPC8360 MDS Board.

After doing tftp the uImage from u-boot, with the bootm command the kernel gets uncompressed and stops there. The serial output from kernel could not be seen.

Source being used:
uboot - U-Boot-1.1.3
linux - Linux-2.6.11 supporting mpc8360epb.
board - MPC8360 MDS

The dump is below:

After Uncompressing kernel, nothing comes onto the minicom.
I have tried the console env in bootargs to ttyS0, ttyS1, ttyCPM0, ttyCPM1, ttyUCC0. But could not succeed.

Anyone Please help me in this regard.

Thanks & Regards

Your minicom is set to 115200, so your U-Boot must be using that, but you'll need to tell Linux too, try:

console=ttyS0,115200

Hi,

1. I copied the ftp and telnet commands to my /bin, and the needed library is also copied to my /lib, but they still don't work so far, can anybody tell me why, thanks!

Hi,

Since there is no "ldd" command in busybox1.1.3, so I copied it from ELDK4.0 to my bin,
but it didn't work, can anybody tell me how to add a new command to my ramdisk ?

bash-3.00# ldd /bin/ftp
sh: applet not found
bash-3.00#

These sound like /etc/services is missing?

Consider adding strace to your build, it saves a LOT of guessing.

Lee

Yes, it is the root cause, thanks Lee!

Hi,

I am now succefully to bring up my kernel on my PPC440GP custom board, but I failed to up my eth0, the eth0 is link down after the kernel is booting up.

There is no effect, after the command ifconfig eth0 up.

Can anyone tell me what may be the root case, and what reason may cause the eth0 unstable, thanks a lot.

below is my log:

Hello All,

I got this problem sorted out.
I have changed the bootargs at u-boot to
setenv bootargs root=/dev/ram rw console=uart,io,0xfe004500 Now i could boot the linux and login.

Thanks & Regards
