Cross development tools under Linux (X86_64)

Petter — Wed, 15 Nov 2006 22:00:30 GMT

I'm new to Coldfire development even though I have some experience programming the 68k Macintosh using MPW in the mid-eighties.

I recently got a 52235EVB and managed to get a simple hello world style application up and running under Windows. However, I would like to do cross development under Linux/X86_64. I've installed a version of (gcc 4.1.0) with m68k-elf target support.

But I would like to know what options I pass to m68k-elf-gcc and m68k-elf-ld to build an object file to upload to the board. Also I would like to know if there are tools avalilable under Linux for writing the flash, or if the flash writing algorithm is described somewhere.

I would like to point out that I'm not looking for an IDE. I'm perfectly happy with Emacs, a makefile, and gdb over a serial line or similar.

Seems like

has most of the stuff that I'm looking for...

I've managed to compile and link (had to change the linker script tough) a hallo world style program using the codesourcery gnu tool-chain. I uploaded the resulting srec file using the dl or dn commands in dbug.

My next question is: are there any public header files and libraries for the 5223x and the
52235evb available?

Hello,

You could download codeWarrior 6.3 special edition, and you will find all headers for coldfire.

The CW header file does not appear to contain any copyright information so I guess they should be ok to use.

Using the CW header files seem to work, but there is more work do be done:

1) The assembly files have to be converted to GNU syntax, not a big job since it's basically to prefix register names with %

2) The linker scripts have to be converted. The link scripts (cfg files) seem to define some of the locations for __IPSBAR, __SP_INIT, etc. I'm a little uncertain on how to do this in a GNU linker or if I should define them in some of the source files.

Have anybody been through this job already? Can I find the already converted files somewhere, or something similar for the GNU environment?

Thanks
