Lock Bits programming problem about avrdudess HOT 9 CLOSED

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"

from avrdudess.

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.

from avrdudess.

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.

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.

from avrdudess.

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

from avrdudess.

There are no errors at 93750 Hz.

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

from avrdudess.

Can you ask a question there? And my English is bad. And I don't know many terms/names.
