Different best difficulty in AxeOs and the pool at version 2.0.7

[chillingbee]

There are different best difficultys in the AxeOs and the pool!
At ckpool my best dif. is about 8.19G and the AxeOs has about 4.29G

Normal.
Pool best diff is your all-time best, since day 1 that you connected to it.
AxeOS best diff is your session best. It resets after reset/power cycle.

We have been saving best diff to NVM for a while now. I should persist across restarts. But I NVM can be reset when uploading a new firmware in some cases.

I am seeing a very similar thing and the differences are pretty drastic. I haven't updated my firmware recently, and the best hash appeared well after my last upgrade.
Running 2.0.7 as well.

  {
   "workername": "X",
   "hashrate1m": "422G",
   "hashrate5m": "442G",
   "hashrate1hr": "506G",
   "hashrate1d": "469G",
   "hashrate7d": "461G",
   "lastshare": 1708830059,
   "shares": 414621980,
   "bestshare": 209250669786.6476,
   "bestever": 209250669786
  },

and on the bitaxe

Results
Hash Rate:	443.68 Gh/s
Efficiency:	35.09 W/Th
Best Difficulty:	4.29G

That´s funny and wierd! Two of my Bitaxe do have the exacly same difficulty of 4.29G

I have the same issue, the I had a best difficulty of 34.9G in pool, but only showing as 4.29G in the miner

[weixiongmei]

Would like to have the session best difficulty rather than just the life time best difficulty in the Home page, because some of the pool doesn't shows the best difficulty...

Hi @skot,

/Volumes/SSD/Codes/ESP/ESP-Miner/components/bm1397/include/bm1397.h:14:38: warning: overflow in conversion from 'long long int' to 'int' changes value from '4294967296' to '0' [-Woverflow]

Yeah I have the same 4.29G best difficulty
