Saving data into local flash memory as a file.

Hi gurus,

I would like to save some sensing data into local flash memory as a file, in order to make then a software application to download directly that file.

It is possible? How?

Thanks & Regards

You'd have to rewrite the bootloader.

Why not use an SD card or the EEPROM? How much data?

Adding to AWOL's questions: How often will the stored data need to be updated? The easiest way to store data in flash memory is to hard-code it in your sketch. Naturally, this means re-uploading your sketch when the data changes. If the data changes frequently, that wouldn't be practical. However, note that the flash memory has limited write cycles anyway.
