Hi Bob,

I started a port to MCF53xx, but it is basically untested. Current state is: compile-clean, ethernet is not implemented (all configuration options involving network have to be disabled), but not tested on a board. I used the MCF52xx for my modifications, as you were already suggested to do.

Hi Wolfgang,

I've followed your directions, which were pretty easy, given I had just done it yesterday for my first attempt. However, when I tried to compile my port of your stuff, it fails in an unexpected area - specifically, it fails attempting to build the tools! To make sure it wasn't my stuff (pretty sure it couldn't have been, but I've been confused before!), I tried to build your cobra5329, using the following:

make clean make cobra5329_config make

I got the exact same error, so it's clear it isn't my stuff. Here is the message

make[1]: Entering directory `/root/u-boot-git/tools` make[1]: *** No rule to make target `/usr/lib/gcc-lib/i486-linux/3.3.5/include/stddef.h', needed by 'img2srec.o'. Stop.

Seems some incompatibility in our respective gcc setup. BTW, I have Gentoo Linux, and am using gcc 3.4.4 - my libraries show up under /usr/lib/gcc/i686-pc-linux-gnu/3.4.4. I don't know how the u-boot build system determines where to look, but it's clearly looking in the wrong place for me! Any ideas?

BTW: Am I to understand the MCF532x family is approximately equal to the MCF537x family, with respect to porting u-boot?

Thanks! -Bob

My problem is that I was not yet able to access the flash on any of my boards (Cobra 5329 EVB and our prototype with MCF5373) and neither dared to use CONFIG_RUN_FROM_RAM (or whatever this option is called).

You can grab my current tree at http://leila.dyna.ping.de/wolfgang/u-boot-git-mcf53xx.tar.bz2

(it is based on what I got some days ago with "git clone", but I do not know if this is really the most actual tree)

To adapt to your board, you should make a new subdirectory in "board", probably starting with cobra5329 as a starting population. Then edit the Makefile in the main directory (probably also taking the lines for cobra5329 as a starting point) and do a "make M5329EVB" (or whatever you want to call your port). You definitely have to edit cobra5329.c (which you also want to rename ;-) ) in the board/M5329EVB subdirectory to use the correct settings for your SDRAM. Apart from that, you are probably on your own, as I am not any further either. :-(

Regards, Wolfgang

Hi,

I'm getting started porting U-Boot to the Freescale/LogicPD M5329EVB board, based on the ColdFire MCF5329 processor. As suggested in the "U-Boot Porting Guide" in the README file, I've subscribed to this list, and I'm admitting I am (currently) clueless - hence this email!

At this point, my only real question is this - has anybody done this already? If so, can/will you share? Or are you working on a similar port, and would you like to share the load? I'm very open to working with others on this, though if there are no takers, I'll go it alone and post it all later.

Thanks, and take care, -Bob
