Re: Flash Encryption Query

Doesn't make sense because if you can boot a firmware with enc/sb disabled then enabling it should boot the same way until it turns on enc/sb itself in the second stage bootloader. You didn't make any hardware changes or other menuconfig changes?

Re: DMA example for UART communication for ESP32

Yes tout interrupt generates UART_DATA event. Other than changing the wait timeouts not really. But you may want to ask do you need to use event queue and double buffered data or can you just do like this https://github.com/espressif/esp-idf/tr ... _rxtxtasks

Re: Bug of deep sleep with GPIO

After wake up from sleep, IO pad used for wakeup will be configured as RTC IO. Before using this pad as digital GPIO, reconfigure it using rtc_gpio_deinit(gpio_num) function.

Re: Bug of deep sleep with GPIO

After you wake up do you use rtc functions to read gpio or configure it back to normal gpio?
