Using Arduino as ISP to burn sketch directly to ATmega328 without first installing a bootloader on the ATmega328

It is possible to skip the Burn Bootloader step. When you do Upload Using Programmer the bootloader is overwritten and thus serves no purpose. However, there is another reason for the Burn Bootloader ...

When using Arduino Uno as ISP does "Yikes! Invalid device signature" mean a bad connection, bad config, or bad version of avrdude?

I had exactly this problem. If the ATtiny is set for external clock, then the ArduinoISP will not be able to program it without an external crystal. Connected a 16 MHz crystal and 2 capacitors ...

Using Arduino as ISP to burn sketch directly to ATmega328 without first installing a bootloader on the ATmega328

The bootloader only enables serial programming of the device; it is perfectly possible to run Arduino programs without it provided that the code is compiled with the same hardware options (MCU model, ...

Suddently, "avrdude: Device signature = 0x000000" with ArduinoISP. Is my chip dead?

Mostly this error is due to connections/powering issues (as already mentioned in your output ). Check connections, especially power and ground also check the resistance between Vcc and GND of your ...

Help understanding how avrdude works with ArduinoISP and why its not working for me

The target board was not reset. The "Arduino as ISP" sketch uses pin 10 to reset the target, not the SS pin. So even on Mega, wire reset of target to pin 10, not to pin 53. Is this an error ...

As Ignacio mentioned, using ISP does not require a bootloader, however, it is also very nearly mutually exclusive with retaining one. Does programming via ISP clear the bootload, if installed ...

Can I avoid having a bootloader if I use ISP to flash to an arduino?

It looks like the Trinket Pro has an Atmega328P processor. You can change the fuses to not run the bootloader, in which case you don't need the space taken by it. I have a hex uploader sketch which ...

Arduino as ISP - program is being uploaded on Arduino, not breadboard

Use the "Upload using programmer" in Sketch menu to upload a sketch over ISP warning, it deletes the bootloader

How can I program a ATmega328 au tqfp32 ( SMD ) chip?

To upload compiled code (.hex) to a bare atmega which doesn't have a bootloader installed you can use ISP. As this stands for in-system-programming you don't have to flash the chip before assembly, ...

How to use reset pin as I/O pin with ATtiny44

The data sheet gives insights: Chapter 1.1.4 states: The reset pin can also be used as a (weak) I/O pin. "Weak" means here, that the output function cannot deliver as much current as the ...

How do I use ATTiny pin 5 (RESET) as a digital output?

RSTDISBL is bit 0 of the high fuse byte. Use avrdude to read the current value of the high fuse byte (-U hfuse:r:-:h), clear bit 0, and then write the value back out (-U hfuse:w:0xXX:m).
