So to me it looks like 1) your sketch has a bug but otherwise 2) the contents of your EEPROM are correct. --- End quote --- Well, this comes to my conclusion, that no ScopeId is stored on that EEProm or I am wrong as only license keys stored? As long this ScopeId is is wrong, no deal to decode the options keys. |

Example 2: As from a different DSO dump: The Scopy ID is complete incorrect 00000000 F0 00 00 01 02 00 00 02 00 00 FF FF 00 00 42 38 ð.............B8 00000010 34 33 39 36 41 38 36 38 43 31 34 43 42 34 00 01 4396A868C14CB4.. |

The options have ScopeID inside (the correct one). 2. Where did you get this dump? Place here the whole dump (or via pm). |

Sorry hpw, I joined this thread to help DaJMasta fix his scope, not explain to you about the scope id ^-^ Try shorting your EEPROM data line to GND or pulling it high with a small resistor and see what happens. An inquisitive mind with the reading skills of a bassoonist should be able to figure it out if he tried a bit. |

In addition the mentioned EEProm Reset Tool :-+ So as @ollopa mentioned, if the the contents is marked as trash, now way to clear the contents and enter the options key as from scratch. This is IMHO all very scare as looking about a dog :-DD |
