Добрый день!
Работал Тион с подключенным дисплеем 5.7". Возникла необходимость переназначить режим порта 2 на RS232. Поправил файл
mxs-auart.c. Пересобрал ядро, и началось:
пингвин стал больше и отображается непонятными цветами, графика вообще вся уехала, такое ощущение что неверно выбран граф.режим.
Прочитал, что обновилось ядро. Решил заново его собрать. Удалил текущую сборку ядра, подготовил её снова:
./ltib -p kernel, далее, применил все патчи.
Разумеется столкнулся с ошибкой
make: *** [_modinst_] Error 1. Решил эту проблему Genues в
http://www.zao-zeo.ru/forum/index.php?topic=747.msg4946#msg4946: файл localversion, удаляем строчку "-zeo" (почему эта проблема не решена???).
Далее, всё успешно собрал, добавил строчку
video=mxs-fb:tag=5.7 в настройках загрузчика. Залил, но результат стал ещё хуже: белый экран, без признаков изображения.
Проверил на др комплекте - результат тот же. В чём проблема?
