Buenas, construí una placa con una ATMega32U4, estoy intentando quemar el bootloader usando un arduino Uno como ISP, pero no lo consigo. He probado casi todo lo que he encontrado en este foro, pero no hay manera.  
Dejo el error que me da, por si alguien me puede ayudar  
Gracias.

He revisado todo y están bien las conexiones , he probado a hacer el Reset manual y conseguí que escribiera pero al final me da este error.

Ahh no usas el comando.  
Dejame investigar como se hace.

No es facil pero este hilo es el mejor que encontré

> hei guys,i want to modify the arduino code slight_smile ,avrdude is readymade and working accepting the new option. @Jantje yes i could do it, but i prefer to recall the flag optionally because it is dangerous as it skips the signature check and goes on programming and could even program a wrong mcu by mistake (more powerfull than -F) option and it could mess with the fuses and brick the chip.

Mira el post 8 me parece el mas adecudado para modificar considerando que los otros requieren tener VSC++

Si usas VSC (Visual Studio Code) éste permite pasar flags y hacerlo con facilidad.

Gracias Surbyte,

Voy a instalar VSC y probare, ya vi algunos videos de como se instala para arduino.

Lo que no entiendo que esta misma placa la hice un un arduino mega (hace algún tiempo ya) y no tuve problemas para quemar el botloader. Supongo que el leonardo será algo mas complejo.

Nada es mas complejo, son AVRs del viejo ATMEL ahora Microchip. Funcionan con similitudes.  
A pesar de que uno crea que las placas son iguales, ya sabes que no lo son. No dije nada brillante, pero solo quiero expresar que no debes asumir que estas en la misma situación. Hay que mirar mas fino y no dejar pasar detalle alguno.  
Siempre esta ahi, solo que no se ve.  
Dejalo x 1 o mas dias y luego vuelve a la carga, a veces ayuda no repetirse en los procedimientos.

Al final Surbyte compre un programador USBASP por 6€ y funciono perfecto.  
Como siempre muchas gracias por toda la ayuda.
