Подключение MMC Flash card по SPI

[Dioptimizer]

Только что обновил LEDE trunk - мод заработал.
Видимо обновление ядра до версии 4.9.57(и более) повлияло на работоспособность.

Вот мой лог загрузки

Напомню:
Это лог первого варианта мода, т.е. без дополнительного GPIO. И SD-карточка подключена через микросхему Gate Inverter к SPI-флеш памяти напрямую.
