 Re: nxt eeprom life cycleThe NXT's main processor is a Atmel AT91SAM7S256. It's rated at 10,000 write cycles: http://www.keil.com/dd/docs/datashts/at ... 256_ds.pdf

Re: nxt eeprom life cycle I have bricks that I've had for years and never had issues with. I flash and reprogram my bricks a LOT. Some friends of mine that write firmwares for the NXT probably do this even more. I have only ever heard of a flash failure once and that was someone who deliberately went ahead and did file IO non-stop. This eventually, after a LOOONG time caused failure.
Keep in mind that if the brick fails because of this, you can easily get LEGO to replace if for you. I wouldn't worry about it, if I were you. - Xander _________________ | Professional Conduit of Reasonableness | (Title bestowed upon on the 8th day of November, 2013) | My Blog: I'd Rather Be Building Robots | ROBOTC 3rd Party Driver Suite: [Project Page] |

Re: nxt eeprom life cycle I'm afraid you can't just load it into RAM and not Flash. I believe nxtOSEK does support this, though, but nxtOSEK is a lot more complicated than ROBOTC. It also means that programs can only be very small (64K) since that is the amount of RAM on the ARM chip.
