esp_reset esp_EN is low

[hustzju]

Hi, I have a question, at host side, after exec esp_reset function, the ESP_EN is LOW, so esp32 is powered off, why?

I don't understand why the code is just like this:

        /* HOST's resetpin set to OUTPUT, HIGH */
        gpio_direction_output(resetpin, true);

        /* HOST's resetpin set to LOW */
        gpio_set_value(resetpin, 0);
        udelay(200);

        /* HOST's resetpin set to INPUT */
        gpio_direction_input(resetpin);

        esp_dbg("Triggering ESP reset.\n");

High-> delay-> low-> delay->high should also have same effect

[hustzju]

I have followed your suggestion,High-> delay-> low-> delay->high. ESP32 is enabled ， but have not got any event，the espsta0 doesn't appear.

Could you give me some advice?
