I'd like to control a GPIO PIN in the deep sleep wake stub. I tried the following code but the GPIO does not turn on. #define SU_HARDWARE_PWRREG GPIO_NUM_23 void RTC_IRAM_ATTR esp_wake_deep_sleep(void) { esp_default_wake_deep_sleep(); gpio_pad_select_gpio(SU_HARDWARE_PWRREG); // Ripped from gpio_set...

Hello, my device is sometimes stuck in the bootloader. This is the last output that I get [2019-01-30 17:34:54] I (12) boot: ESP-IDF v3.1.2-dirty 2nd stage bootloader [2019-01-30 17:34:54] I (13) boot: compile time 15:34:11 [2019-01-30 17:34:54] I (13) boot: Enabling RNG early entropy source...

I have this problem too after using Bluetooth. Current is slightly above 1mA when BT was used and well below if not.
Did you ever find a solution for this?
Thanks

I also have this problem. Anyone has a solution for this?
Thank you

Hi John,
did you ever find a solution to this problem? I'm trying to understand the difference between ORIG and EVED and which one is better?
Thank you

I have this problem too.
Is there any solution to prevent this message?
Thank you

Just solved this myself.
I need to reconfigure the SDA line upon recover from deep sleep:
Then I2c works as expected.

Hello, I'm using I2C and deep sleep in my application. And I want to wakeup ESP32 by low level on SDA line. After hard reset I can receive data in I2C slave mode without any problems. The same code fails after configuring SDA for deep sleep, entering deep sleep and waking up. I2C setup code: i2c_con...

Sprite, you're right that the first SDMMC slot is shared by the flash (SDMMC_HOST_SLOT_0).
The second slot (SDMMC_HOST_SLOT_1) is directly wired to the SD card holder in ESP-WROVER-KIT v3.
So I guess the reason for the crash is something else.

Hello, I've two ESP-WROVER-KIT and the SD card example crashes always on one board, and works with the second one. The example is exactly as provided by IDF, only with modified SD slot number: sdmmc_host_t host = SDMMC_HOST_DEFAULT(); host.slot = SDMMC_HOST_SLOT_1; This is the console output: I (298...
