Is there loadable driver support--insmod etc., for the M5249C3 ?
If so, where can one find relevant instructions ? Also, I am

Hi all,
I'm trying to compile a Hello World loadable kernel module for 2.6,

Edge Port Module LKM working for the MCF5275, but that's somewhat
irrelevant right now.
From the make output, it would appear that MODPOST can't find

Hi,
I'm trying to build an LKM for the MCF5275 Edge Port Module, based on
Phil Wilshire's which was posted a while back. His was written for
2.4, but I'm using 2.6, so of course the module build process is
different. I'm getting an error during the MODPOST stage and I'm
wondering if anyone

Specifically, I want to know what uClinux interrupt line is mapped to

For example, QSPI interrupt, which is source 18 on INTC0 would
be vector 64+18, so vector 82.
Thanks for your help, Greg. That magic 64 number is what I need.

Hi all,
Some background: I'm trying to use the mcf_qspi driver on an MCF5275
with 2.6.x. Originally, I had some problems compiling it, but after a
bit of hacking, it's compiling and initializing at boot. I've created
a /dev/qspi node in the ROMFS, and open() and ioctl() seem to be
working.
Hi,
Can anyone tell me where to find the MCF5275 Interrupt Vector Table?

I'm wondering what files I need to include in a user application to

Searching the web, it seems like I need some combination of these files:

Thanks for your replies, I just want to make sure I'm understanding
everything correctly here:
You could probably backport the 2.6.x driver to 2.4.x fairly easily.
Depends on how many of the new toys it uses :)
There is not a driver in 2.4.x that will work with Coldfire I2C? I'm
