Repairing a broken Arduberry



Ouch … that was my fear. Do you think I could repair it by changing the ATMEGA328P? Is it enough to buy a new blank component or should it be preprogrammed with a special bootloader ?

Do you know how I could test my AVR ?

Thank you in advance for your help.


You can get some ATMega328’s from Mouser, desolder and remove the old one (It would be pretty hard). And solder the new one. After that you can simply use it with the Raspberry Pi. We don’t use a bootloader on the Arduberry so the only thing needed to be done is to burn the fuse but that should be pretty straightforward.



Hello Karan,

Thanks for your response !

Well, I’ve ordered a new blank ATMEGA328P, I’ll receive it next week.

There’s a IC socket for it on my Arduberry, so no need to desold.

I’m a little confused about the “fuse”. I’ve found some informations on this site :

But it’s still a little unclear for me. Do you know where I could find more precise directions about what to do for burning fuse(s) ? Do I have to build some specific electronic assembly for that ? I’m going to read Atmel specs for trying to better understand this.

Many thanks by advance.
Best regards


The fuse settings are:
LFuse: 0xFF
HFuse: 0xDA
EFuse: 0x05

Put the new chip on the Arduberry, note the orientation of the old one before you put the new one in.

Once it’s properly mounted, run: avrdude -c gpio -p m328p. The chip should be detected.

Next burn the fuses one by one:
avrdude -c gpio -p m328p -U lfuse:w:0xFF:m
avrdude -c gpio -p m328p -U hfuse:w:0xDA:m
avrdude -c gpio -p m328p -U efuse:w:0x05:m

Once all three are done, your Arduberry is ready to be used.



Ok ! I let you know when I’ll receive my new chip and perform the handling. Thanks again.

Best regards



Well, I received my new chip this morning. After exchanging it my Arduberry is now working !

Many thanks for all the advices.
Best regards
