* [U-Boot-Users] Testing a cross compiler for a mpc8540 cpu @ 2003-12-30 19:13 Matthew S. McClintock 2003-12-30 19:22 ` Ed Okerson 0 siblings, 1 reply; 4+ messages in thread From: Matthew S. McClintock @ 2003-12-30 19:13 UTC (permalink / raw) To: u-boot 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 -- Matthew S.

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.

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?

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. - kumar On Dec 30, 2003, at 1:26 PM, Matthew S. McClintock wrote: > That seems like a good idea.
