Процессор не грузится с SD карты! Если отдельно записать FLASH, то плата запускается нормально! Читаю память iMX51 - GPIO_BT_SEL = 1, конфигурирование с GPIO заблокировано! Можно вернуть к заводской прошивке? На работающей плате fuse такие-же, но загрузка с SD карты работает!

The processor is not loaded from the SD card! If you write FLASH separately, the Board starts normally! I read memory iMX51-GPIO_BT_SEL = 1, configuration with GPIO is blocked! Can I return to factory firmware? On a working fuse Board are the same, but loading from the SD card works!

Это и удивляет! С помощью JLINK читаю регистры на рабочем процессоре и на этом. На обоих GPIO_BT_SEL = 1! Но рабочий грузится с SD карты, а второй нет. 

This is surprising! With JLINK I read registers on the worker processor and on it. On both GPIO_BT_SEL = 1! But the worker is loaded from the SD card, and the second is not.

Hi Sergei

>Can I return to factory firmware?

unfortunately blown fuses can not be reverted to original state.

It is OTP (One Time Programmable) fuse.
