This helps tremendously, especially in the fact that now I can actually boot and run the kernel on my fads... while the ADI & mpc8bug are connected. Before that, I would always get the InstructionTLBMiss exception - and of course, mpc8bug didn't really know anything about the address. Also, I'm also now running in "stand alone" mode - with the ADI & mpc8bug disconnected. Straight from the flash. For me, this is great news. I know that most of you don't give a hoot! :) So, I'm attributing this recent success to: A) Setting SYPCR in the rom code fairly early on. B) Issuing a "rms der 0" to mpc8bug when it is connected. I'm a happy camper at the moment. Mostly. :) I just need to get my regular system setup to allow bootp and host an nfs root for the fads. Also, I just noticed - the kernel couldn't mount root, so it's doing its "Rebooting in 180 seconds.." act. However, about all I'm seeing after that is a: <0>Kernel panic: Kernel Mode Software FPU Emulation and then the duo is repeating every 180 seconds... Not quite what I call a reboot. I would think it would at least manage to restart the rom initialization code. Anyways, thats relatively minor... have a good night! -Dan ** Sent via the linuxppc-embedded mail list.
