Dear vlado
Hi to you and to all the members
I have an xprog m v 5.0 and i tried to updated
To v 5.5.1 but i got the atmega dead so i changed
The atmega 64
And now whe i try to program it it always
Give ff ff in all lines on flash and eeprom
I tried with usbasp and extreme burner
And with mini prog tl 866a
Same result
Can you please advise
Thanking you in advance

TL866A owner here:

Here are the steps:

1. You do not need to remove the ATMEGA64A MCU or any pin from Xprog.
2. Make sure your connection from TL866 to XProg are correct. TL866 has only 1 ground output so you need to make sure you split the ground connection to XProg.
3. Once you've verify the connections are correct. Here the most important step. Make sure you supply Xprog with a 12V dc. If you don't do this, it will not work.
4. Open MiniPro program and set the "Interface " to ICSP port and make sure ICSP VCC enable is check.
5. Select ATMEGA64A @TQFP64
6. Click on Check ID icon, it should show you the chip ID, mine read "1E 96 02". If no Id are shown, recheck your connections.
7. If it successfully read the chip ID than proceed to the next step. We are now ready to program the ATMEGA64A
8. Click on "Code Memo" ===>File open ==> select the flash file Mr. Luis provide. After you select the Flash file, a next screen will pop up. Just make sure that "Code Memory" is selected. Now click ok.
9. Click on "Data Memo" ===>File open ==> select the eep file Mr. Luis provide. After you select the eep file, a next screen will pop up. Just make sure that "Data Memory" is selected. Now click ok.
10. Click on "Config" check only the following items:
"Fuse Low Byte" BOOLEVEL=0, BODEN=0, SUT0=0
"Fuse High Byte" SPIEN=0, CKOPT=0, BOOTSZ1=0, BOOTRST=0
"Extended Fuse Byte" None
"Lock Bit Byte" LB2=0, LB1=0
11. First Erase the chip
12. Than click on Program
13. If all goes well, you should see successful at end of the programming state.
14. Now disconnect TL866 and the 12V power supply from Xprog.
15. Open Xprog 5.5.1 program provided by Mr. Luis
16. Make sure you select the correct USB COM port under Option ==>Enviroment.
17. Click on Update
18. Once the update is complete, you should see a successful message at the end.
19. Done!
