Use the DENX cross-compiler, unless you are VERY familiar with gcc3.3-isms
Compiling u-boot under gcc3.3 powerpc hosted on x86 is possible, it is
just a HUGE pain getting the environment right unless you have done that
sort of thing before.

If you don't realy want to learn all the pitfalls and obstacles of
building a working cross toolchain you can simply download our ELDK
and use this one.

Hey, there. I am working with the MPC5200 Lite, and thanks to the
suggestions of using ELDK, I successufully (I think) compiled a boot image
for the 5200 under RH9_i386. I used the patch for lowboot (although, because
patch on RH9 didn't seem to like the diff file regardless of "-p" levels, I
had to apply it with VIm). I move the jumper over, hit the reset button, and
I get this on minicom:

The BAUD settings appear to be the same as I've been
successfully using with the Motorola dMon (115200), and it seems to be
writing to minicom quite legibly, but it doesn't seem
to be reading the serial port. Any suggestions where I could look to see
why? The ethernet is at its default of bootp, but I didn't think that shold
make any difference to the serial terminal. I'm also curious about it
booting the image at 0x100000 (doesn't exist, obviously), but I expect I'll
figure that out once I see how to set up initrd (or whatever ramdisk is
needed).

Did you make sure to disable all handshake (software and hardware) in
minicom? Most probably minicom is waiting for some modem handshake
lines which are not set by the MPC5200 serial driver.
Better, avoid minicom. See

Well, you can also read the output and follow the instructions:

I'm having some trouble with the lowboot config on the MPC5200LITE.
In looking through the configs, I notice, where TEXT_BASE=0xFF000000
#define ENVADDR=CFG_FLASH_BASE+30000
Since the u-boot image goes from FF000000 to FF035250, this would
appear to drop the environment inside the u-boot code. This is apparently
confirmed by the fact that when I do saveenv, u-boot will not come up
anymore. (this is without setting any environment variables, even).
When I write a virgin copy of u-boot to the flash, the addresses at FF0030000
appear to hold something other than environment values. After saveenv, they
hold environment variables, and everything after the values is filled with
zeroes (and u-boot is dead).
Is there a particular reason for having the ENV below the end of the u-boot
image? Is there a better place to put it? Possibly the beginning of the next
sector (0xFF040000)

This is the problem. The U-Boot image should never get that big. It's a bug.

Yes, there was a configuration error which caused the environment to
get embedded instead of placed at the intended location.

The location at 0x0xFF030000 is OK (as long as U-Boot doesn't grow
much); just the configuration was wrong. Sorry.
Thanks for pointing this out!

Thanks! That fixed the problem. I figured it was something like that when
the image shrank by one block when I moved the ENV up to FF04000. If I can
just figure out how to build an initrd when I don't have any of the ppc
executables, I think I'll be in business. I think I'm going to have to dust
off the old Apple 8500 and see if I can figure out the yellowdog install.

You have all the PPC executables when you install the ELDK :-)
Also you can download a ready-to-run image from our FTP server: see

D'oh! That works! I've got it booting BusyBox. What threw me is I was
searching all over the ELDK tree for anything that looked like "initrd."
Once I knew what to look for, I also found another possible in the Metrowerks
BSP tree. Didn't think to look for ramdisk. Next stop: IDE. It LOOKS like
there is support for the internal IDE in the kernel config (MGT 5xxx?)...

So far, it looks like it's working good (without DMA :-). I've been able to
mount an ext2 partition under a directory in the ramdisk. One odd thing I've
had is that I can't seem to use a compressed uImage since I added the IDE
config. If I gunzip the vmlinux.gz and use mkimage to create an uncompressed
uImage, I can upload it to 100000, change kernel_addr to 100000, and run it
just fine with flash_self (I have the initrd in flash at ff180000).
If I use the SAME vmlinux, and create a gzipped uImage, it starts to boot,
then has a fatal error while trying to uncompress the image (this happened
with the image that was created with "make uImage," which is why I started
monkeying around to begin with.) Oddly, though, the gzipped uImage file I
made wasn't exactly the same size as the one "make uImage" made -- different
gzip versions? "mkimage -l" seems to like the image, so the header is okay.
I can't help but think that this has something to do with the size, since
there's not much else that gunzip cares about. The "stripped" uImage is
670072 (0xA3978) bytes compressed (I don't remember the uncompressed size,
but I think it was about a meg and a half), and the IDE-enabled image is
785281(0xBFB81) compressed, and 1887000 (0x1CCB18) uncompressed.
Could the gunzipper be running out of allocated space? I certainly have
enough flash to store an unzipped kernel image, but I don't like mysteries.
On this processor, too, it takes only a split second to unzip the kernel, so
boot speed isn't an issue.
In looking around for memory allocation defs, I did find a typo in
cmd_bootm.c:
#if defined(CONFIG_MPC5XXXX)
Every other reference I've found refers to "CONFIG_MPC5XXX"
Thanks again!

This just means that your kernel image has become too big to be
loaded at 1 MB; try downloading to and booting from 0x200000 instead.

It's overwriting the image as it uncompresses.
