I noticed that AVRDUDE 5.5 is now available and supports usbtiny. Have you tried it yet?
The current version (5.3.1) that supports usbtiny also has an annoying bug for some chips that was fixed in AVRDUDE 5.4.
Code: Select all
avrdude: Device signature = 0x1e9502
avrdude: safemode: Verify error - unable to read lfuse properly. Programmer may
not be reliable.
avrdude: safemode: To protect your AVR the programming will be aborted
avrdude done. Thank you.
