вероятно у вас кастом-борд
попробуйте с простейшего - прописать один порт, потестить на стабильность, потом исправить на второй порт - аналогично..
смысл действий - проверить, что интерфейсы независимо исправны..
хорошо бы проверить чистоту питания, хоть карточки кушают мало, но мало ли источник уже на пределе..
как понимаю - подтяжки вверх стоят..
это по аппаратуре..
по софту - смотрите внимательно, как в драйвере проходит инициализация ресурсов - по симтоматике смахивает на обработку прерывания "не для того порта" или ее отсутствие..
беглое гугление показало, что 2 карточки для 9263 редкость, т.ч. драйвер может быть с ошибками..
содержимое борд-файла в части прописания sd/mmc и схему подключения не спрашиваю - на ваше усмотрение..

На любой вопрос есть любой ответ.
