Hi all
Just got my USB-ISP programmer from MCS and it's alot faster then my o ld200/300
However, I cant write EEPROM contents from the Bascom AVR ISP Programmer.
If I change a value, press Write buffer to EEPROM or Auto program chip, it looks ok, but when I read back the data, nothing is changed... :S

Anyone have any ideas as to what is wrong?
Flash programming works fine.

Found out that you have to load a saved EEPROM image from disk for it to work.
If you just enter the programmer, edit some bytes and try to write, it doesn't work.
But if you save that after editing and then reloads it, it writes ok...
