Hello Dave,
Just got through watching the videos, and thank you
again for doing this. Definitely pulled a lot of ideas and issues together
for us.
I have a couple of follow-on questions that arose
during the videos:
1. When you are copying the uClinux kernal
image from the RAM to the FLASH, what format is it in and where is it actually
going? I thot that the FLASH was used under the JFFS2 file system to
be a mountable drive under uClinux, while the .BIT file loaded to RAM was raw
binary. What am I missing here? Is the FLASH somehow
partitioned? Is so, where is that defined?
2. You mention that for IP protection, you
can encrypt the bitstream and use a matching DES key set in battery-backed
storage in the FPGA. Does the Spartan-3 support this? If not, what
experiences have you had in protecting IP on that platform?
Thanks,
Jim Law
