This document details the silicon errata for the ESP32

Errata

• When ESP32 is powered up or wakes up from Deep-sleep, a spurious watchdog reset occurs
  
• When the CPU accesses external SRAM through cache, sometimes random read and write errors occurs
  
• When the CPU accesses peripherals and writes one address repeatedly, random data loss occurs
  
• The Brown-out Reset (BOR) function is not functional. The system fails to boot up after BOR
  
• The CPU crashes when the clock frequency switches from 240 MHz to 80/160 MHz
  
• The pull-ups and pull-downs for the pads with both GPIO and RTC_GPIO functions can only be controlled by the RTC_GPIO registers. For these pads, the GPIO pull-up and pull-down configuration fields are non-functional
  
• There is a limit on the frequency range for the audio PLL
