Topic: Load the bootloader using AVRStudio (Read 1 time) previous topic - next topic

How I do it is via  isp, using the avr mk2

And set the fuse brown out voltage , and set it for 8mhz extranal xtal.
If you get it wrong you can just re change the settings after.
But it all depends on what xtal mhz , chip etc.

I have this problem some time ago...I ask in avrfreaks and all answers were that I only can reset this fuse using a Higth Voltage programmer.

No , I think if you have a isp programmer , I don`t think you can brick it.
I`ve installed the bootloader on 3 168 chips so far and loaded a hex file direct to the chip so cutting of the need of the boot loader, which frees up 2 extra k

Here are the relevant fuses, as shown in AVRStudio:

Nope, with just an ISP programmer, you can 'brick' an ATmega. The easiest way is choosing an impossible oscillator setting or disabling SPI. (Notice above how AVRStudio can't alter this value in ISP mode.)

Conveniently, the AVR-Dragon IS a high voltage programmer.
