Hello friends
Please help to restore my Xprog 5.84 clone one, with UPA 1.3 v progammer
Xprog 5.84 is not working well since i bought it, one time bearly read eeprom but since then device is silient fault or communication error fault, in short not working properly, I would like to downgrade to 5.55 version as people say it works good with 5.55 version
Please help to program Xprog Atmega64a with UPA 1.3v USB Chines clone
Now when I connect Xprog its appaering on PC port as Xprog but when i try to update or check athuriation its showing device is silent.
Before it was updating (while internet off) and showing software authorization
I downloaded from forums 5.5.5 version flash and eeprom, lock and fuse setting have. (if there is better version Please advise also)
I tied all options: like read, verify, clear, program operations while Atmega is in Xprog board, and also unsoldered it and tried directly on Atmega64 to read, verify, erasing, progam operations...
Unfortunatily
when you erase eeprom or flash, eeprom is fully erased but flash not erasing fully, even if you repaet 3,4 times erase, still something is not erased on flash memory
after writing eeprom or flash I read to check if it is written correctly, but not writing all eeprom or flash,,,
I did it 3.3 volts or 5 volts UPA setting, setting J Open/Close not
result is same
Please tell me what is problem ?
