[microblaze-uclinux] Video tutorials - follow on questions



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,
