Добрый день. Пытаюсь завести u-boot на процессоре NIOSII (больше для изучения, чем для практических целей). Но при инициализации u-boot зависает. Судя по логам решил, что это как-то связано с serial девайсом. Прошелся отладчиком, увидел, что зависание происходит в функции display_options при вызове printf.

int display_options(void)
{
	char buf[DISPLAY_OPTIONS_BANNER_LENGTH];

	display_options_get_banner(true, buf, sizeof(buf));
	printf("%s", buf);

	return 0;
}

Прошу подсказать куда копать дальше.

Следовал туториалам отсюда: https://www.rocketboards.org

U-boot брал здесь: https://github.com/altera-opensource/u-boot-socfpga

Тулчейн собрал с помощью crosstool-ng

Хм... Оказалось что в дереве устройств адреса надо указывать учитывая смещение MMU (0xC0000000). Странно, как тогда у авторов статей с rocketboards работало без смещения.

Было:

Или может быть поддержка MMU включается каким-то конфигом в u-boot?
