I cannot seem to get the formatting write but hopefully you see what I mean.

Doing some math, I think I know what one of the 800 MHz diff values is for. I swear I’m terrible at math and have no idea how I saw this :-).

00f0 vs 00ee = If my math is right, this is a counter going backwards from 255 (ff). It seems to correlate with your number of flashes if I guessed your order. Because originally your post said “flashed 14 times before”, well the max hex value is FF, so if you subtract 14,15,16,17 etc. you end up with the values your showing in and order that seems to fit your flashing sequence.

255-14=241
255-15=240 (00f0)
255-16=239
255-17=238 (00EE)

If I’m right, it’s likely a counter that when you reach 1 or 0, it will stop you claiming you’ve used up the reliable flashing writes? In other words maybe the designers placed a 255 flashing limit for whatever flash they used?

Tell me if you think that math works. I’d image the rest is a CRC or other kind or checksum/rolling counter to verify firmware image integrity on a basic level?

I swear it just came to me, tell me if you think I’m on to something.
