Repeating last byte for all addresses

[8BitMark]

I'm having some difficulty with writing to the 256 eeprom. If I link pin 8 of the 74HC595 to GND the eeprom erases but won't write the test data. When I remove these the correct number of test bytes are written but they are all set to the value of the last byte of the test string. Any help would be appreciated.

My guess is that you might be seeming the DataPolling output. This sets the data for all address to the last write value while the internal memory is being written. It should stop after about 10ms?

I am having this issue as well, did you manage to fix it?
