CPU will run deep sleep stub first, and then proceed to load code from flash. Some flash chips need sufficient time to pass between power on and first read operation. By default, without any extra delay, this time is approximately 900us, although some flash chip types need more than that. By default extra delay is set to 2000us. When optimizing startup time for applications which require it, this value may be reduced. If you are seeing "flash read err, 1000" message printed to the console after deep sleep reset, try increasing this value. config ESP32_EMAC bool default y if ETH_ESP32 default y if MDIO_ESP32 default n help Hidden option to enable the ESP32 Ethernet MAC driver.
