Hi all, need a little help and Google is not helping much.
I have purchased a USBASP v2.0 for ISP programming attiny & atmegas. Its working fine on an attiny85, I can upload the blink sketch and it runs. So far so good.
At the moment the tiny is running at 1MHz but I want to set the fuses for 8MHz. So I select "ATtiny85(internal 8MHz clock)" as board and "USBasp" as programmer and click "Burn Bootloader" but I get:
avrdude: invalid byte value ({bootloader.unlock_bits}) specified for immediate mode
avrdude: read from file '{bootloader.unlock_bits}' failed
Error while burning bootloader.
Any ideas where I get this missing file, and where it should go?
I am using IDE 1.6.5 on Ubuntu 14.04
Thanks very much in advance for any help/suggestions.
Thanks, the instructions on that link worked great.
To summarise for anyone finding this thread later, I added https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json to "additional board manager URLs" in File-->Preferences, then opened the board manager (under Tools-->Board) and installed the attiny option.
Because I am using Ubuntu, I also previously created the file /etc/udev/rules.d/99-USBasp.rules and put the following in it: SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="05dc", GROUP="dialout", MODE="0666"
