DIY Moteino Mega - Bootloader and fuses
« on: March 13, 2019, 08:20:58 AM »
Hi! :)  I have made a DIY Moteino Mega based on the R2-USB schematic. So far, the circuit seems good, and the voltage regulator outputs 3.3V as it should.

Now I'm trying to burn the bootloader and fuses. I was only able to get a JTAGICE MKII, which only seem to work with Atmel studio 7 (AVRDUDESS did not work properly).

I have used the DualOptiboot_V5.0_atmega1284p_BlinkD15_SPIdisable .hex for the bootloader. But I am little unsure about the fuses and lock bits.

In Atmel studio, I get the following registers.

EXTENDED: 0xFF
HIGH: 0x91
LOW: 0x62
LOCKBIT: 0x00

Can I use these registers? I don't want to do anything before I'm sure if it works..
