Last time I saw numbers on this, it was for the configuration memory on
a TAPR TNC-1.
The documentation said 100,000 writes, but it only counted if you
actually flipped a bit -- and it was per-bit, not per word or across the
entire device.
That means re-flashing with the same firmware shouldn't count at all,
since you're writing the same bits into the same words in storage.
I'm sure current parts are better.

Hi All,
I'm constantly doing projects with microcontrollers and
programmable logic devices. I've been doing this long enough that I've got
devices that have "lost their memory." Things that I designed and built
decades ago no longer function. Over time flash will lose its mind, I guess
just like we do.
At some point in time that will happen to our lovely little radios. From an
operator stand point we can re-flash the firmware as long as the boot code
is functional. Does Elecraft have a provision in the radios that will allow
an update of the bootloader to keep it fresh, so to speak? That is without
sending it back to the factory?
I know a lot of people don't keep stuff forever, but I pretty much do. In
old radios we replace caps, and a few other parts that age. With
programmable chips you need and ISP, unless there is another provision.
