[U-Boot-Users] Problem building U-boot for RpxLite with Mpc823e

Sorry I meant the RPXlite section in the U-boot project.

I was talking about Readme file : "doc/README.RPXlite" file. I thought that 
the section 1 might be obsolete.  With the documentation of my RPXlite, I 
have'nt found any VisionClick flash programmer.

About the documentation link you've sent me, I read everything except the ELDK 
section.  I did compile a u-boot, u-boot.bin, and everything without any 
error messages.  (Compiler used is 2.95.2, just in case).  Before writing 
everything into the flash memory, I wanted to test it by loading it into the 
ram and execute the binary file.  ( the same way I do when I want to run 
linux on the box, I load a kernel at 0040 0000, and then run the code 
starting at 0040 0000 or 0041 0000 (when the 64k ELF header is not 
stripped)).  And as for the u-boot binaries, they do not want to run, and I 
get no error message, my RPXLite either reboot or freeze.

I also tried the u-boot.srec, just in case the S-record image would run 
better, but it did'nt.  I guess that's why I'm looking for someone who could 
give me a few hints about how to run u-boot.  

As I understand it (and maybe this is where my problem is) I am supposed to be 
able tu run u-boot's binary (or s-record image) directly from the ram. Now, 
this task seems impossible to me.  I even tried to run the elf binary in the 
linux box that I have made (mounted via nfs) and it crashed (Segmentation 
fault error only)

I know these questions might sound "newbee" to you guys, but I really need to 
know if this code is suppose to work alone, without any kernel, or it 
absolutly need to work under linux (a bit like when you run lilo from a 
"normal-i386" linux box)

I thank you a lot for your time, this is really helpful.  Like they say, the 
firsts steps are always the hardest and theses are my first in the embedded 
world...
