Есть микроконтроллер ATtiny85 и программа - под виндой для прошивки пользуюсь унипроф (программатор Громова - http://easyelectronics.ru/avr-shag-p...grammator.html) флэш нормально стирается и программируется, соответственно программа в микроконтроллере работает как надо.
В линукс для прошивки пользуюсь avrdude делаю всё под рутом. Винда и линукс на одном и том же компьютере.
Вот строки в конфиге avrdude.conf для программатора Громова
programmer
id = "gromov";
baudrate = 9600;
desc = "serial port banging, reset=dtr sck=rts mosi=txd miso=cts";
type = serbb;
reset = 4;
sck = 7;
mosi = 3;
miso = 8;
;
Сразу скажу что комментирование строки baudrate = 9600; результата не принесло.
В начале стираю командой:
avrdude -P /dev/ttyS0 -p t85 -c gromov -e -v

Вроде как кристалл не стёрся, но стирание вроде прошло нормально.
Естественно программа на микроконтроллере работает не так, причём иногда бывает так что записывается без этой ошибки, соответственно тогда всё работает нормально.
Подскажите пожалуйста в чём может быть проблема!!
За помощь заранее благодарен!!!!
