eeprom failure. please help.

mctrivia

For some strange reason I keep getting "eeprom programing error on com 12". this is on multiple boards. in fact only 1 of 6 didn't give me the error. This is not a problem I usually get.


Running F10 results in everything working properly on all boards. Multimeter shows 10k ohms between SCL and SDA to Vcc and infinit to ground and pins around it. meter also shows 0 ohms to the eeprom.

Any sugestions on where else to look?

problem solved. There was a second device trying to write random data on the scl and sda lines while I was programming.
