EEPROM verify failure

3hex

Hi

I am new to this forum and basic stamp in general, I have searched for help on this subject
but have been unable to find anything, sorry if it is a simple or obvious or answered question.

I have the BS2 on a GROWBOT board which I am trying to get to know how to use.
It only has the 2 servos, 2 led's and piezo speaker.

I have writen and dowloaded a few basic programs which worked and ran OK so I am sure that I
am doing everything correctly, all of a sudden when attempting to download it responds with a

"EEPROM verify failure" error message

Does this mean the EEPROM is damaged, it has only been written too a few hundred times?
How do I go about fault finding this?

Thank you in advance

Jeff

No, this is the "Generic" error you get whenever there's a noisy communication line between the PC and the BS2.

Causes:
1. Worn out EEPROM. Only happens if you've been using the "WRITE" command.
2. Loose cable.
3. Flaky connection IN the cable.
4. Low power supply/low battery
5. Bad grounding -- either serial cable to board, or battery to board, or both.

I have never used the WRITE command so it should be one of the other things you mentioned.
Thank you for the detailed response, I should be able to fault find it now.
