XPROG Clone Repair

[jakesman]

new problem xprog was 5.3 with dongle updated to 5.5.5 but was not very stable and went back to 5.5.1 all good but after time starting to get verify errors and wrong reads so reflashed and something went wrong during the flash wit fuse and lock bits and now device is silent , desolder the eeprom and read it al FFFFF reprogram the eeprom with a dump now xprog identify when i put usb cable but it looks like the atmega is locked or busted , i put 4Mhz ossicillalator on crystal pin of atmega to see if it will wake up but no luck , Should i replace the atmega64a or another way to wake it up ?

oscilator not is 4Mhz ,is 11,059Mhz.not work with another quartz.this value ist specified in configuration word.

[jakesman]

ok but how do i wake the atmega chip up , it looks like it had a problem when programing it with the lock and fuse bits ?
atmega fuse recovery

hook up an oscillator (not a crystal) to the clock line on the atmega.
(any freq, usually 4MHZ)
erase the device with your ISP program, then reprogram the CLSEL fuse.


The above works 99.99% of the time!

yes,i know this program for erase atmega.i dont know for what raison your atmega not wake-up ,after erase,maybe ist broken.i use evrytime for this work upa for programing,and ist very fine.

wel i ordered new ones , strange the eeprom i put in another programmer it all read FF FF FF and ftdi chip also no data the whole xprog got wiped clean no lights not reconized by usb nothing , so reprogram eeprom from a dump i got here reprogramed the ftdi chip and now it reconize it when plug in usb but for sure atmega is dead , options , buy xprog repair set $45 and maybe it stil not work , replace atmega $1.00 and reprogram , or new xprog , damm this thing started with verify errors and after reflash it is dead i use TL866A ISP to flash it never had problem even did it with AVR extreme burner so i am sure atmega is not locked but busted

Hi mate
try erase atmega, (flash & eeprom)
progarm lock bits all "true"
program your fuse bit (for xprog)
program flash memory
program eeprom
set lock bit false, false true, true, true....

and be happy

report..

thanx for reply
with avr extreme burner first time it was good , second time i use it when it start with verify error it give message "incorrect chip selected " like WTF there is only 1 atmega64 in the menu but it did flash and after that it just refuse to connect "fail to switch power" so with avr no go , tl866 isp it ID the chip as 00000 and if i power it the id change to FFFFFF i can erase it and program it like u said all ticked but it stops with error chip not blank but with blank check it is good , u tried thanx mate but this i will keep in mind for future , just gona replace the Atmega chip then i will come back here and report

is best way to change Atmega.i think is burned,for this is unstable

[f2f2]

Xprog original ATMEGA64 files
Reading Xprog box ver.5.7.2 and Xprog box ver.5.7.5



with original PC software Certification need Authorization only official registration

restore old version only atmega64 rewrite

1.chip erase
2. all fuse bit setting and program...
3. lockbit all TREE =all 1...
4. write eeprom block
5. write flash block
6. lockbit lb1 lb2=0 False and program...

ok
finaly got replacement chip , used avr extreme to program it ver 5.5.5 and also had problem with it then i saw that one lock bit is not correct in the instructions and wow now my xprog lives again and is even better performing than what it use to it is more stable and reads faster than before , maybe they use cheap low quality chips in factory
