[U-Boot-Users] Testing a cross compiler for a mpc8540 cpu
Does anyone know a good way to test to see if a cross compiler is working? I have what I believe to be a cross compiler for a mpc8540 cpu. However I am not sure if its working. I can compile u-boot with the compiler but that does not tell me much since u-boot does not support the board I am using specifically. I really don't want to go forward working on getting u-boot to run on this board only to find out of compiler is broken. Anyone have any ideas?
Thanks
Use the UNIX command "file" on the output of the compiler. When I do this on u-boot I get:
# file u-boot u-boot: ELF 32-bit LSB executable, MIPS, version 1 (SYSV), statically linked, not stripped
This shows that it is a little-endian (LSB) executable for MIPS.

That seems like a good idea. My output is the following:
u-boot: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), statically linked, not stripped
However what I am worried about is the fact that I am using an e500 processor. I am told there are subtle differences, however I am not entirely sure how. However the file command makes no mention or not if this is compiled for an e500 processor. I have little doubt that my compiler makes code for a PowerPC processor. I guess my question should have been how can I verify if my cross compiler produces code for an e500 processor code?
Thanks, Matthew

Matthew,
A few things that may be useful. 1. from an application stand point the main differences focus on floating point and availability of new SPE functionality. Pure integer code that runs on PPC should work (Compiling app code with -msoft-float -mno-string) 2. for building u-boot/kernel style code a standard PPC compiler with a new binutils (2.14 or greater) should be sufficient. 2.14 or greater adds support for the full Book-E and e500 ISA and the -me500 option to the assembler.
Hopefully this provides some help.
