Posted - 06/06/2005 : 16:01:49 I have the dual power programmer and i cant get it to program my 2732 chips. It says chip read ok, verify ok, and device empty, but i get an error message when i try to program it. it says ERROR at 0x000000 CHIP= 0xFF Buffer=0x4A Ive notice that 4a is the first set of numbers in my hex, and ive also noticed that the checksum isnt right when i load the bin into the program. How do i change the vpp? could this have something to do with it? I cant find the jumper settings anywhere on this site. HELP |

The checksum in software is a simple-add-on checksum. As long as every time load the data you can get same checksum, then that is OK.
