problem with ESP32 before run

[pdemianczuk]

Hi, since yesterday my board had a strange behavior


I have a log from monitor like that:

first time:
rst:0x10 (RTCWDT_RTC_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371
ets Jun 8 2016 00:22:57

after reset and I again attempt to connect
ets Jun 8 2016 00:22:57
