![]() High Voltage Serial Programming is a separate programming method and this does not apply to newer ATtiny devices with a Tiny Programming Interface (TPI) such as ATtiny10. So, what is now the best solution for AVR High Voltage Programming? This was available on AVR Dragon, STK500 and STK600 but since these have been discontinued, there is a lack of suitable programmers. This is looking more hopeful, but at this point it seems like my schematic just doesn't work.The only way to re-enable Reset or SPIEN fuses on some older AVR chips like ATtiny13A, to allow them to be reprogrammed, is to use High Voltage programming (HVP) method.

Is there something wrong with my schematic, or with my software approach? Again, I'm a complete beginner to this, so any information at all is useful.ĮDIT: I plugged it into a different USB port on my computer and now lsusb lists: "Bus 001 Device 020: ID 03eb:2ff4 Atmel Corp. ![]() I tried the command avrdude -p m32u4 -P USB -c avr109 to intialise it, just in case that port happened to work, but the output was: avrdude: ser_open(): can't open device "USB": No such file or directory However, when I pressed the reset button, I couldn't find which port it's communicating over. ![]() I assumed that when I pressed down SW1, the bootloader would activate and and the device would register as a serial device on my computer, so that I can program it using avrdude. Now I've soldered all the parts onto the PCB, and I've plugged a micro usb cable from my computer into J1. ![]() I made a PCB with the following schematic: This is my first time trying to program an Atmega32u4. ![]()
