    @mfalkvidd If the ATMEGA is detected then all you have to do is input the Fuse Bits and program. It should work. Just select the bootloader hex file in Flash. Check Set fuses and hit program.

    @Suresh-Mali the Uno is detected, but the Uno works fine. I am not able to detect the Pro Mini, which is the one I want to load the bootloader on.

      After more experimenting and reading I have concluded that I am clearly in over my head. I need to understand the basic concepts before I continue. @m26872 has graciously offered to help IRL so hopefully we'll be able to figure something out.

        Adding the result of my experiments with Nick Gammon's ISP tools for future reference.

        This is from a working Pro Mini:

        Atmega chip detector.

          These are from my failed attempts at uploading new bootloader to the working Pro Mini, which resulted in a Pro Mini that can no longer load anything using FTDI but it can still be accessed over ICSP (which the first Pro Mini can not, so I seem to have done something different this time).

          I hope to one day be able to explain all this, so someone else can avoid making the same mistakes.

            These are from my failed attempts at uploading new bootloader to the working Pro Mini, which resulted in a Pro Mini that can no longer load anything using FTDI but it can still be accessed over ICSP (which the first Pro Mini can not, so I seem to have done something different this time).

            I hope to one day be able to explain all this, so someone else can avoid making the same mistakes.

            @mfalkvidd Do you have an USBasp? It works great burning bootloaders. You will be able to recover the fuse as long as you have not set the fuse to disable SPI. If SPI is disabled then the only way to recover is using High Voltage Programmer.

              I don't unfortunately. I have borrowed an avrisp mk ii but I haven't been able to get it working.
              I can absolutely buy an USBasb but if I am unable to get the avrisp mk ii to work, I will probably not succeed with the USBasp either so I need to learn more first.

                By the way, I found http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p&LOW=E2&HIGH=DA&EXTENDED=FD&LOCKBIT=FF for calculating fuses. I find it easier to view than Engbedded's fuse calculator, and it is possible to link directly to any fuse settings which is really nice.

                  @mfalkvidd AVRDudess works with AVRISP mkii as well. Have you tried to detect the Pro Mini chip using AVRDudess+AVRISPMkii. Are you able to detect the chip using Mkii in AVRDudess?

                    @Suresh-Mali I have tried, but without success. See the last three paragraphs in http://forum.mysensors.org/topic/3304/bootloader-and-fuses-for-pro-mini-3-3v-using-arduino-uno-as-isp/11

                      Finally some success!
                      I am now able to read and write the fuses on my Pro Minis using Arduino as ISP.

                      I have uploaded the Arduino as ISP sketch (File->Examples->ArduinoISP in the Arduino IDE) to my Uno and connected the Uno to the Pro Mini as per the instructions in the sketch. The key was to use -b 19200 as parameter to avrdude, without that I'm unable to connect.

                      Log from reading the fuses:

                        And I'm also able to upload a new bootloader to Pro Minu from Arduino IDE using an Arduino UNO as ISP.
                        The ArduinoISP guide says that I might need to put a capacitor between reset and gnd on the Uno, but what I had to do is put a capacitor (0.1uF) on between reset and gnd the target Arduino Pro Mini.

                        I don't understand why I need to do that, but uploading fails (avrdude says "verification error") 10 out of 10 tries without the capacitor. Upload is successful 10 out of 10 times with the capacitor.

                        This is the log from a successful upload, in case it is useful for anyone else:

                          The cap definitly has to on the programmer (uno) between reset and ground. Otherwise when you try to reset the target board for reprogramming you just reset the programmer (and then the programming fails).
                          Strange that it worked the other way.

                            After visiting @m26872 and getting great insights to his workflow and his projects, I can report this:

                            • The avrisp mk ii I borrowed from a co-worker does not work. So that's why I wasn't successful using that device. AVR Studio gave some helpful error messages, much more helpful than Arduino IDE, so lesson learned: Use AVR Studio when troubleshooting.
                            • Using my Arduino Uno as ISP worked fine at his place, even without the capacitor. When I got home, I tried 10 times without the capacitor and all but 1 were successful. Strange. But at least it works :)
                            • We were not able to revive any of the 4 Pro Mini i "bricked" when experimenting. Good thing they are so cheap :)

                            A BIG thanks to m26872 for helping me and for a nice visit to his home.
