...it crashed, possibly because the memory was overloaded.

It's nice to see that code jockeys still think that memory is unlimited. It's a universal constant that I've grown accustomed to.

Here's what I don't understand.

From watching the press conferences, I know that the rovers each have 512M bits of flash memory, divided into two 256M bit mirror image partitions.

Now 256M bits / 8 = 32M bytes. If Spirit had 13,000 files, and assuming 100% flash utilization (unlikely, to say the least), that's 2.5K bytes per file, on average.

If I mis-understood the bit/byte thing, then that's still only 20K bytes per file on average.

I have a hard time believing that the file sizes are that small.

There is 128M bits of RAM, and some EEPROM, how much I don't know. I assume there is a boot loader or somesuch in EEPROM, and I know (from the press conferences) that at least some of the actual run-time image is in flash, further reducing the memory available for file storage.

Anybody got a clue? I sure don't.
