"EEPROM programming error on port COMx"

Hi,

I've been working with the prop recently and I was programming it (the EEPROM) today, and this message popped up:

"EEPROM programming error on COM27"

I have no idea why it is saying this, maybe I need to restart my computer. I am currently using prop tool v1.3. Anyone have an idea what it could be and how I could fix? I might just be a simple restart, haven't tried it because it takes such a long time to boot up my computer.

Thanks,

John

    EEPROMs can go bad, but I would recommend restarting your computer first before replacing your eeprom. Mine drops out on me sometimes as well. If this is the first time programming that eeprom, be sure you have your 2 data lines correct and not backwards. I made that mistake yesterday as well.

    A little off topic, but if your computer starts up slow, you should probably get Ccleaner and run it to clean up a bunch of junk from your computer as well as disabling unneeded startup programs in your msconfig :)

    Hi John.

    First of all -- Have You attached any EEPROM to Propeller (Propeller don't have any internally)
    Second -- That EEPROM need be at least 32KB else more but never smaller.

    Is your EEPROM soldered to a board (if so what board)? Is it on a breadboard?

    As Tim said, it's easy to get the wiring wrong when using an EEPROM on a breadboard. The wrong size of jumper wires will also cause problems when used on a breadboard.

    Do you have a multimeter to check continuity to each EEPROM pin and where it's supposed to connected?

    You have a 10K pull-up resistor on the EEPROM's data pin right?
