Post HOW TO NOT DELETE ON NXT
Is there any way to prevent files to be delected on NXT ?

I really need it, there is any firmware that allows it?

Thanks

Deleted by the user or by the system or when you upload a new FW?

The idea is the NXT be on a exhibition.

So, the public(user) should not be able to delete anything...

I only want that the NXT execute one (or two) programs.

it is possible to , for example, when i turn on the robot, it will execute the program ? and nothing else would be available?

In that case, when we (programmers) want to delete anything, we upload the regular firmware...

You could set the number of exitclicks verry high in your program. No one can exit your program this way and thus not delete it.

maybe try to set the number of exit clicks to a negative value...

first, like ford said, negative exit clicks if possible. next, make sure that your nxt can't turn off because of a time limit (if you have looping code, put alive(1); (maybe mess around with the alive number too make it work better (negative number?)) somewhere in frequently running code. next, for keeping it alive battery wise, get the rechargeable battery pack with the powercord taped (duct taped) to the battery, and tape the power adapter to the wall also. as of actually keeping everyone from the programs if they reset the nxt, well there isn't a fix. Make sure to cover the reset button on your robot.
