Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : How many Erase / Rewrite cycles can I put my Pico's through?

Every time I edit a BASIC program on my Pico, it erases and rewrites it to the device.    
And the same thing happens every time I make a tweak to the MMBasic firmware.  The device gets erased and rewritten.

How long until I start to have problems?

Around 100,000 so I wouldn't worry about wearing it out.

Just get a spare. Or two. :)

At 4-writes per hour, 24 hours day, 365 days per year, that would work out at about three years minimum if there's no wear-levelling. That's for the flash, of course, there's no restriction on RAM. In real life you could probably expect at least three times that.

Wow!   Thank You so much for the information....

I was trying to figure out and resolve as many bugs and problems as possible before I did an erase / rewrite cycle.    I'm glad to know that isn't necessary.

If you are really concerned then there are versions of MMBASIC for the PC Windows and Linux

(Linux)

(Windows)

Obviously the IO parts of the pico ext will not be available, but if you are just sorting out standard routines then it's a useful testing setup.
