I believe it does, problem is I'm "emulating" JTAG via a parallel
cable on LPT1. I'll try and get a hold of a USB JTAG cable and connect
it directly to the Parallel III (or IV) connector on the board. Will
this help?

That's what I was curious about, I chose the base SDRAM address as the
start address (in my case 0x81800000), I guess that was correct since
I was able to mount the FS, unfortunately it crashed seconds later..

Here's another concern. I cannot seem to "RESET" the soft-processor
(through XMD), I basically need to re-implement and re-upload to
restart the boot process.

Any advice would be helpful, I personally don't mind hacking around
with the kernel, but I will not attempt to do so until I resolve the
upload speed issue.


Thanks,

Edmond
