*SOLVED* Built a Pro Mini - What fuse settings?

Projects Programming
1

i built my own pro mini from the sparkfun's files so there is a 16MHz resonator on it. i have an avr isp MKII programmer in addition to the arduino ide 0022.

i can read the settings from within AVRStudio just fine - it is a blank chip so all the 'stock' settings are in there. i have the hex for the bootloader from the arduino ide, but i thought i need to set the fuses first w/ AVRStudio. please advise.

also, when attempting to use arduino 0022 to burn the bootloader from it, regardless of what port it select i get an error about a usb error. even when i have no com port selected and just select the pro mini board and then go to the bootloader section and select the avr isp mkII programmer, again, an error about no usb programmer - but it is there since it is working fine w/ avrstudio.

running win7 64bit - i have programmed other atmega328p before w/ no issues, so if somebody could let me what fuses need to be set that would be great.

thanks,
bob

ps - i have read the tutorial here about programming the bootloader for the mini/pro mini but it does not talk about any fuse settings

Have you tried burning the bootloader through the Arduino IDE? It will take care of the fuse settings for you.

tried that, but the arduino ide doesn't see the avr isp MKII programmer if you have the jungo usb drivers that are installed when you install avr studio 4, but i did get the bootloader on it through the arduino ide on a different xp machine that has never seen avr studio 4...

i ended up using the drivers that are here - C:\Temp\arduino-0022\arduino-0022\hardware\tools\avr\utils\libusb\bin on a xp machine that doesn't have avr studio 4 on it for the avr isp mkII as i had read they don't play nice together. after that, the arduino ide did see the avr isp mkII and i was able to program the bootloader through the arduino ide on that machine, but not the machine w/ avr studio 4 on it.

kind of a weird way to get from point a to b, but i am @ b so all is good now :slight_smile:

Thank you for the follow-up.

no probs, hopefully it will help somebody out.
