I am new to this program and don't know if I am doing something wrong, but when I write to the at28c256 eeprom, the verification fails at address 0x19C0.

Found TL866II+ 04.2.132 (0x284)

Erasing... 0.02Sec OK

Writing Code... 6.69Sec OK

Reading Code... 0.47Sec OK

Verification failed at address 0x19C0: File=0xD0, Device=0xFF

Upon reading the file from the eeprom, the file has FF writen from 19C0 to 19FF, the file also has FF from 59C0 to 59FF I don't think the chip is bad because I was able to write a file with no problem using xgecu's windows software a while back
