Hi Eric,
I have the same board and same problem. It's just an incompatibility between the
DTB and u-boot.
Recent u-boots (and without a doubt also your u-boot 1.3.3) expect aliases
in the DTB, these ones I guess:
.
.
aliases {
ethernet0 = &enet0;
ethernet1 = &enet1;
serial0 = &serial0;
serial1 = &serial1;
pci0 = &pci0;
};
.
.
Not being able to find alias "serial0" (in the DTB) causes this problem.
see u-boot/common/fdt_support.c:fdt_fixup_stdout
Older u-boots don't expect them. My REV A4 board was shipped with
"U-Boot 1.1.6 (Aug 24 2007 - 13:10:12) MPC83XX" (which obviously not expects
the aliases).
If I flash a new/custom u-boot (U-Boot 2008.10) the problem occurs.
I assume Freescale ships their REV A4 boards with a u-boot not expecting the
aliases.
I assume your u-boot 1.3.3 is not the one the board was shipped with,
are are you saying it is ?

Hello,
This is getting frustrating and I am beginning to think someone messed this
board up and returned it. I would think it would boot up the default flash
image out of the box with very little trouble.
Board is a MPC8313e-RDB Rev A4. I set the dip switches per the instructions,
S4 all off and S3 all on.
Uboot comes up but I can not boot either the default images in the flash or
images I built with ltib and tftped. I did not touch the flash. I get
WARNING: could not set linux,stdout-path FDT_ERR_NOTFOUND and ERROR: /chosen
node create failed - must RESET the board to recover. The board resets.
A friend has the same board but his U-Boot is Version 1.3.0 (Jun 19 2008 -
13:41:53) MPC83XX and some environment variables are different. I do not have
the BOOTCMD variable but entered it manually.
I tried searching for on a solution but it is confusing because if aliases are
needed why does the default dtb in the flash omit them?
This is what happens:
