Your cap is going to the reset pin on your uno. I think it actually is supposed to go to the reset "line" from uno to BlueSaab (pin 13? Can't remember which pin is used as reset). Give that a try. On Thu, Nov 24, 2016 at 13:58 PetrW [via BlueSaab Forum] <[hidden email]> wrote: Hello All!

I tried reconect reset directly or disconect reset and happend little diferent error:
avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature. I found this: http://www.avrfreaks.net/forum/does-device-signature-0x000000-mean-atmega-bad looks that its some trouble with crystal

Hey mate,
Encountered a few similar issues when going through the process. In the end, it turned out it was a faulty solder connection somewhere. I went through and checked all connections and reheated them to ensure a proper connection was made. I recommend doing that before going too much further. Viv |

Ok thanks I will check it again, worst case I will resolder Atmega 328 from UNO :-) Petr W 2016-11-25 5:41 GMT+01:00 viv.g [via BlueSaab Forum] <[hidden email]>: Hey mate,

It looks like one of the pins on the crystal near the can chips is shorted to the case, which is ground. That shouldn't matter for the uploading but check that you don't have the same issue on the other crystal. No shorts, anywhere.
Also, make sure you're following the proper directions for burning a bootloader; you need to have ArduinoISP sketch uploaded to your Uno (you can't have anything connected to the uno while doing this), THEN you select the new programmer (Arduino as ISP), then connect to BlueSaab ISP header, then hit burn bootloader. You have to have the right 328 (if it's not a 328P, the chip signature won't match, but we're not there yet; it's a fixable problem).

Ok thank you very much for help ! I ordereded parts from Mouser chip which came i Atmega 328 AU its correct ?

I think that’s the “wrong” chip, but it will still work, it will just take some more work to get it to work because when the software tries to upload, the chip signature won’t match (it looks for a 328P and a 328 won’t match). It’s just a matter of changing a small value to get it to upload, but it can be confusing. Don’t worry about that until it happens.

Hello all,
I tried change chip signature in avertude.conf but still I couldn´t burn bootloader. There can be possibility that I some how bricked chip with fuses and ext / int crystal settings. SO finaly I used Atmega chip from my 3$ UNO clone and before unsoldering I also uppload CDC sketch to chip. I think this can be nice source of prebooted chips for beginers which don´t have programing skills but must have soldering skill :-) https://goo.gl/photos/wJMucr4FV8xd9XEU8

Are you using windows or mac? On windows, there are actually TWO locations for AVRDUDE.CONF and you have to modify the CORRECT one. And of course, the easy one to get to is the WRONG one. You have to navigate to a hidden folder in local_settings in your user folder, then navigate and find it there. If you modify that file, you should be able to adjust the signature to the chip that you have.
Of course, doing it your way works too :)

thanks ! Yes I have widows and I changed wrong one :-) 2016-12-01 15:11 GMT+01:00 Seth [via BlueSaab Forum] <[hidden email]>: Are you using windows or mac?

As I became, kind of, master in handling BlueSAAB v3.x (hardware and software) I decided to update my v4.2 with Karlis latest code.
I did it with the USB cable and selecting Arduino Uno as a board in Adruino IDE software... at that time I thought, "it won't work, I'll have to adjust settings, dig into parameters files, etc." BUT none of this was needed, I only had to select "download" and whoaaa O_O it did the job in seconds ! I knew that there was a big step in hardware between v3 and v4, and that's real ! We too often come on forums to say what's wrong but it's so pleasant to also mention when it's great ! Seth and Karlis, you are Gods ! Next step, burning bootloader to 328's on v5 I just finished to built :-D Cheers

Glad it worked so easy! Thanks for the compliments; Karlis & I must be doing something right 😁
Let us know if you have any trouble burning the bootloader; it can be tricky.
