Исхоные данные: плата SK-iMX6S/D-SODIM, материнская плата starterkit для неё, buildroot-2014.08-sk с ядром linux-imx_3.10.17_1.0.2_ga-sk и неизменённым файлом imx6qdl-sodimm.dtsi, пустая sd карта на 2Гб с файловой системой FAT. Ситуация следующая: после загрузки платы, если вставить карту памяти, то она определится и примонтируется. С ней можно работать, считывать и записывать данные. Если карту извлечь, то появится соответсвующее сообщение. Однако если вставить карту памяти до загрузки платы, то при загрузке возникнет сбой и зависание системы. Вот вывод коносли:

Мог бы кто-нибудь проверить у себя загрузку с неизъятой картой памяти?
Аналогично поведение и на сторонней материской плате с модифицированым файлом
imx6qdl-sodimm.dtsi. В этом случае присутсвуют 2 разъёма sd карты(sd1 и sd2). Загрузка с любой неизъятой картой памяти приводит к краху и зависанию.
И ещё один вопрос касаемо подключения карт.
Вот так происходит подключение карты памяти SD1:
mmc0: host does not support reading read-only switch. assuming write-enable.
mmc0: new high speed SD card at address b368
mmcblk1: mmc0:b368 00000 1.83 GiB
mmcblk1: p1
А вот так происходит подключение карты памяти SD2:
mmc1: host does not support reading read-only switch. assuming write-enable.
mmc1: new high speed SD card at address b368
mmcblk1: mmc1:b368 00000 1.83 GiB
mmcblk1: p1
mmcblk1: error -84 transferring data, sector 64, nr 56, cmd response 0x900, card status 0xb00

mmcblk1: error -84 transferring data, sector 840, nr 8, cmd response 0x900, card status 0xb00

mmcblk1: error -84 transferring data, sector 1032, nr 8, cmd response 0x900, card status 0xb00
mmcblk1: retrying using single block read
В обоих случаях с картой можно работать, но чем могут быть вызваны ошибки в начале при подключении кары SD2?
