Lock Bits programming problem
Sorry for my bad english. Google translator.
Thank you very much for your development. I really like your program.
When programming atmega168p/328p, attini45/85 an error occurs when recording Lock Bits. This happens if factory fuses are installed in the microcontroller and I do the firmware of the microcontroller and fuses automatically. This doesn't always happen. Two times out of ten.

I've noticed you have added an addition command line argument of -B0.5 (bit clock at 1500000 hrz) which is too fast to program chips with the stock clock settings. This will override your default setting and cause issues.
It does not help. I remove this setting and set the frequency to 187.5kHz. Error again.
And I still don’t understand why the default frequency is 375kHz? At this frequency, the microcontroller will not be programmed with factory settings (internal quartz).
Therefore, I use the firmware for usbasp with automatic frequency detection. https://github.com/dioannidis/usbasp
This error occurs on any usbasp firmware.
375KHz is the default frequncy that AVRDUDE uses (or maybe it's the default of USBasp, I'm not sure) if no -B option is supplied.
As for your problem, try enabling verbosity in the Options panel. That might help tell you what's going on.
I don't know what to watch. Tests have shown that there is no error with verbosity 4. I am attaching the files.
verbosity_1_error.txt verbosity_2_error.txt verbosity_3_error.txt verbosity_4_NOerror.txt
Question about settings manager. All settings are saved. Problem with "bitclock" setting. It is saved in the presets.xml file. But when selecting a saved preset, "bitclock" is not set.
Hmm, it could be a timing thing. Verbosity 4 might be slowing avrdude down enough that it just about works. Does it work without verbosity and a very slow clock?
Can confirm the bit clock restore problem, I've made an issue here #68
Ok, it's a timing thing with AVRDUDE. I think it would be best to make an issue over at https://github.com/avrdudes/avrdude
Can you ask a question there? And my English is bad. And I don't know many terms/names.
Your English is fine :) Put a link back to this issue so they can see what's been happening. Title it something like "Fuses sometimes fail to write"
