Короче дело явно в частоте. Ячего-то не понимаю, но я меняю в at91_mci.h частоту, а она всё равно 400000. Что бы я туда не писал. Не пойму, как так может быть...

Так, с сообщением понял. mci_write с участием CLKDIV из AT91_MCI.H выставляется после вывода сообщения. Соответственно сообщение от него не зависит.

Ушёл читать даташит про MCI, может прояснится чего...

Цитата

Короче дело явно в частоте.

Частота у всех одинаковая, но неработает только у тебя. Так что дело явно не в частоте :) Например у меня частота MCK другая из-за нстроек plla но частота все равно почти такая же:

mmc0: clock 400000Hz busmode 1 powermode 2 cs 0 Vdd 20 width 0 timing 0
clkdiv = 122. mcck = 399609

Дык а какие ещё варианты-то могут быть? Вроде платы все одинаковые, тем более 24е ядро что-то особых проблем не испытывает...

БП, карточки не пробовал менять ?

Интересно, а почему у нас с вами powermode разные???

Меня больше интересует почему у тебя логи покалечены, или это просто издержки копипасты ? Ничего что я на ты ? powermode одинаковые а вот Vdd разные, но у меня в начале тоже такое значение, потом оно переключается на Vdd 20
