Combined deep sleep and sdmmc causes write to fail (solved)

[druffer]

Both the deep sleep and sdmmc examples work on their own, but when I combine them, the sdmmc write tests fail after coming out of the deep sleep. The logs below show everything working properly on reset, but when I push the button connected to the deep sleep wakeup, I get "sdmmc_write_blocks failed"

This is probably caused by the 'rtc_gpio_isolate(12);` call in the deep sleep example: https://github.com/espressif/esp-idf/bl ... ain.c#L177

Since the SD card uses GPIO12, you need to call 'rtc_gpio_hold_dis(12);' once you exit the deep sleep, to re-enable this GPIO.

That fixed it, thanks
