Thanks Frank, I actually have seen that, but it looks like an internal module, not an external module... unless I'm missing something. I've tried configuring a few drivers that used bestcomm as <M>, and once I used insmod on them they complained about all of the bestcomm API functions as missing.

It's an external module, and I'd like to use Bestcomm with it. I've already tried a bunch of horrible things to get it to work. I could say it's close, but by close I mean the FEC still runs, my stuff doesn't. 1. Can the Bestcomm I/F be used by an external module, or is the module required to be built in if built-in drivers use Bestcomm? TasksInitAPI (no so bad) and TasksLoadImage (yeah, bad) aren't really supposed to be called more than once from what I've read, and the kernel loads them for ethernet and ATA (no disk in my system if that matters). 2. If it can be used by an external module, how would I do it? I've tried compiling the source into my module and replicating the initialization the kernel does in addition to my own stuff. It's not too bad, though I don't get any interrupts yet. The LTIB from Freescale includes AIC23 and AC97 drivers that use Bestcomm. I built my kernel with them set as modules, and they had the same unresolved problems that my driver has on insmod, so I'm pessimistic. If someone could put me out of my misery one way or another, I'd appreciate it. Might check out the driver posted by Bob Petersen: http://ozlabs.org/pipermail/linuxppc-embedded/2005-September/020210.html using DENX linuxppc_2_4_devel/arch/ppc/5xxx_io/ i2s.c, psc.c and Bestcomm/ Frank Thanks.
