Hello,

I found this register field: RTC_CNTL_BROWN_OUT_CLOSE_FLASH_ENA which in the header file says it's hw reset value is 1, but in the he reference manual, the reset value is 0. I want to make use of the brown out feature, and I'm interested in:
- a description of this register field
- what's ...

Hi,

Many thanks for fixing the issue. I cannot apply it from the patch you sent, as I use esp-idf v3.0 and there is a big refactoring of the bootloader between the master branch and v3.0, so we will retrieve this patch with further esp-idf updates.

Any idea if this patch will be included in the ...

Hi ESP_igrr,

I've sent you a private message with the binaries.
Hope it helps!

Thanks,
Valentin

Dear Espressif Support,

When testing a small application, the board (ESP32 WROVER kit v3) reset infinitely inside the boot-loader. See in the attached file the exception that occurs.

It is not a power surge issue, as this kind of exception usually is, as the board is supplied by external 5V supply ...

Hi xiaoxufeng,

Thanks for your answer. I have some updates on this topic.
First of all, I got another ESP32 board to be the SPI counterpart, to be sure I don't mess something up on the SPI slave. So, 2 ESP32-WROVER-KIT are connected now.

Then, I changed the GPIOs I use to be sure I use non-native ...

I wired 2 ESP32 WROVER together via SPI, to be sure I don't have an issue on the STM32F7 board, but things are not improved. I also changed the SPI pins to fit with the esp32 example:

#define SPI_MODE 0 // Default SPI mode 0

#define SPI_CLK_GPIO GPIO_NUM_15 // Shared with JTAG/MicroSD
#define SPI ...

Hello all,

I try to use the ESP32-WROVER-KIT as an SPI master and a STM32F746DISCO as an SPI slave and I am having some problems with the communication. I use the latest official release of the esp-idf, v3.0.

Below the ESP32 configuration and code snippets:

#define SPI_CHANNEL HSPI_HOST
#define ...
