[AVR] AT328P Revive suggestion

[johnny78]

hello guys

i have an mikro prog AVR Programmer which its was a bad choice to buy
i have alot of AT328 chips Bricked by doing nothing but reading it on AVR Flash
any suggestion to get a programmer can revive those chips?

thanks
Johnny

How to Fix Dead Atmega and Attiny Avr Chips

How to Fix Dead Atmega and Attiny Avr Chips: Atmega fusebit doctor, as name says it, device for repairing dead Atmega and Attiny family AVRs by writing fabric fusebits. Most common mistakes or problems are a wrong clock source (CKSEL fusebits), disabled SPI programming (SPIEN fuse) or disabled…

do you think it can set the fuse bits back by programming through parallel?
thanks for suggestions

I had an AVR locked for the same reason that the programmer from the above link proposes to fix, the incorrect setting of the clock source in the fuse bits; however in that case unfortunately the device was SMD and I had to desolder and scrap it. The correction procedure is exactly as described, programming through the parallel port dedicated to this purpose. BTW, in my opinion this was a cruel decision by Atmel, not everyone who did the same mistake that you had the IC socked on the board (e.g non-Arduino based projects).

so you think building this circuit will help ?
oe should i look for Parallel programmer?

thanks

Hi,

At first I'd verify the failure cause.
Are you sure it is the fuse programming?

Maybe ESD killed the devices. Or a bad power supply....or something else.

hi Klaus

my chips killed with MikroProg Programmer
i thought maybe reading them will give me the default fuse bits programmed
but when reading each one it gave me errors & the chip isnt usable anymore
i have contacted them but they dont have any solution
i want to understand what is happening & find a solution to revive those chips
i have almost 9 of them dead
not for this 9 chips only for sure But for future cases
i didnt made any mistake anyway No wrong fuse bits set or anything else

thanks
Johnny

If you have an Arduino Uno/Nano, you can try to make:

Might be that the fuses are wrong. If not, ask refund for s----y MikroProg programmer.

i couldnt find the arduino sketch for this project
would you please help ?

thanks

C'mon, it is easy to find sketch, just follow links in the article.
Do your own search.

Hello Guys
is there a programmer which can make this solution for me ?
can the mkII do this job for me
or any suggestion please?

thanks
