Hi! I have a dumb question about booting up an i860. In the hardware reference manual, under section 8.9.2 Certain Gotchas when Debugging with i860 Microprocessor, it says "After reset, the instruction and data cache may contain data so the cache flush procedure should be used to reset the instruction and data cache." How do I get the boot code into cache in the first place? Is there a possibility that the cache contains random data and "thinks" that the boot location (0xffffff00) is cached and refuses to read the real boot code? Wilson Chan wilson@athena.mit.edu
