проверьте качество питания МК. Бывает фантомной запитки хватает при потоке данных, а вот с фьюзами начинаются проблемы.

проверил - эффекта не дало.

PS: на Arduino Pro Micro стоят танталы на 10мкФ до и после LDO + керамика
пробовал подключать коротким качественным кабелем microUSB (20cm) на заднюю панель.

Ну у меня последняя идея - притормозить всё как следует

Эммм, а avr109 - это вы не системный загрузчик(SPI) используете, а свой? Может в этом проблема?

да, шью встроенным бутлодером. он не умеет прошивать фьюзы?
могу для чистоты эксперимента попробовать avrisp, но надо будет подпаяться.

Что-то я совсем того... http://microsin.net/programming/AVR/avr109...rogramming.html
Этот загрузчик не умеет записывать fuse-биты. По простой причине: программа МК не имеет никакой возможности менять fuse-биты. Собственно от них[fuses] зависит её[программы] работа )))

Alternatively,
the Boot Reset Fuse can be programmed so that the Reset Vector is pointing to the Boot Flash
start address after a reset. In this case, the Boot Loader is started after a reset. After the applica-
tion code is loaded, the program can start executing the application code. [b]Note that the fuses
cannot be changed by the MCU itself.[/b] This means that once the Boot Reset Fuse is pro-
grammed, the Reset Vector will always point to the Boot Loader Reset and the fuse can only be
changed through the serial or parallel programming interface.

нда.. рано радовался.. теперь выдает такое после первой перешивки фьюзов:

Код
avrdude -F -p atmega32u4 -c arduino-ft232r -P ft0 -U lfuse:w:0x90:m -U hfuse:w:0xd9:m

avrdude: Device is not responding to program enable. Check connection.

avrdude: Device signature = 0xe80ed1
avrdude: Expected signature for ATmega32U4 is 1E 95 87

не понимаю - как вообще Device signature могла смениться??

встроенный - это тот, который SPI использует.

сигнатура не менялась. просто МК не отвечает.
Там фьюзами случайно SPI не был выключен?
Ещё может быть установлен тип генератора не тот.

разобрался в чем накосячил - выключил кварцевый генератор - настроил на внешний клок, вот он и затих...

теперь вот какая непонятка: не могу снять защиту с бутсектора.
фьюз LOCK=0x2F а я хочу туда залить 0xFF - как?
