Or with the resonator removed you can apply an external clock signal to the xtal1 pin of the target chip, using an alternate version of ArduinoISP sketch that provides clock out such as Adafruit's version. I suppose you could remove the resonator and replace it and see what happens. The supporting circuitry on the board, such as the resonator, could be bad. Double and triple check your wiring before going any further. There is a 16mhz resonator on the flight control board, is this of any help in diagnosing my problem please. When I looked at the error output above it says "Oscillator : Off" When I googled this it seems to possibly point to the fact that there is no functioning oscillator in the micro. So I assume that the crux of the problem are the lines Reading | # | 100% 0.02sĪvrdude: Device signature = 0x000000 (retrying)Īvrdude: Yikes!

Can I do this and if so how do I connect it please. The bit that I am having trouble understanding is that I look at pins 10, 11, 12 and 13 on the Uno and yes D11 is Mosi, D12 is Miso, D13 is SCK so they all correspond to the same pins that are available at the FCB programming pins but D10 on the Uno is SS, which I think is Slave Select? but the other pin required on the FCB is RST not SS as on the FCB. This is when I thought that maybe I can flash the FCB Atmega the same way with the Uno as ISP. Icircuit resize driver#Then I went to try and flash the Atmega that is in circuit on the FCB, via the programming pins on it but as I said the USBasp programmer will not work because of a Windows driver issue that I cannot resolve. Yes prior to thinking about trying to use the Uno to flash the bootloader onto the Atmega32u4 on this flight controll board (FCB), I soldered a Atmega32u4 to a breakout board and successfully flashed the bootloader onto it and verified its success by uploading a modified blinky to it. ![]()
