Hi Scott.
What type of board and processor do you have? What is the version of the RPX utility program?
The CPU model is MPC850SRZT50. Version: RPX-Lite BW 850SR 50Mhz/8Mhz Ic ~Dc RPXU v1.39
I finally got the cross-compiler stuff setup (x86->ppc), but in the final linking stage of compiling the kernel, I get a whole bunch of 'undefined reference to...' errors (whether or not I have 'Set version information on all symbols for modules' defined). I found that commenting out the offending symbol EXPORT lines in arch/ppc/kernel/ppc_ksyms.c got rid of most of the errors (mostly isa/pci stuff and a few other things that it seems the RPX board doesn't support, and I also tweaked a Makefile to exclude ADB support). The only error left is:
arch/ppc/kernel/kernel.o(__ksymtab+0x0): undefined reference to `request_irq'
I also get:
uart.c: In function `serial_console_setup':
uart.c:2705: warning: zero-length format string
which doesn't seem critical, but makes me wonder whether console on serial port will work correctly.
I am using the embedded-2.2.5 sources I got from the linuxppc.org ftp site. I guess they're not completely setup to compile cleanly for the RPX-Lite (on my x86 RH5.2 system anyway). I'll try booting your kernel, but in the end I've got to be able to compile my own. If all else fails, if I gave you my .config could you build a kernel for me?

I'm trying to load the zImage.rpcg.srec-2.1.127 kernel...
That's a pretty old kernel too. Download the 2.2.5 sources and build a newer one.

Is it possible for you to post a v2.2 kernel in SREC format,
I have a 2.2.5 kernel for the RPX-Lite 823 board that I will upload to the linuxppc.cs.nmt.edu server. If that matches your board, give it a try. I am just on a slow telephone line right now, so it may be a while before it is up there :-).

... and/or the program you used to convert the binary kernel to SREC format so I can compile a custom kernel?
I attached the program "
zsrec.c", which is a simple S-record generator I use for the kernel. To run it is pretty simple, "zsrec zImage > /tftpboot/zi.rpx". It creates the S-records to load at0x200000, which works nicely on the RPX. You can also get objcopy to do the same thing, but it took less time for me to write this program than to figure out what command line parameters I needed :-).Good Luck. Have fun.
