It is in a portable medical device that reads 3 sensors regularly. 3 V rails have been brought up. 7. I don't think that (without changing the hardware) there is a way to figure out the external watchdog monitor reset you. After a SW ESP32 contains a hardware random number generator, values from it can be obtained using esp_random(). ino Receiving CPU0 reset reason: POWERON_RESET CPU1 reset reason: EXT_CPU_RESET Boot number: 1 Gets here setup Interrupt gets here Battery power switched ON ESP32 wake from Deep Sleep Interrupt gets here Battery power switched OFF ESP32 going to Deep Sleep @ơ b\ x After successful restart, CPU reset reason will be SW_CPU_RESET.

Reset vector code is located in the mask ROM of the ESP32 chip and cannot be modified. I'm not able to find the exact reason. Code: Select all. The value can be read in ESP32 Okay, taking off my Espressif hat and speaking on a purely personal basis here: seriously, a medical device, on a chip with WiFi/BL and as such a huge attack surface on it, with Arduino as a base, and you ask here how you can retain potentially-corrupt data in RAM after a reset because of who-knows-what reason? We got a batch of a hundred boards that we designed around the ESP32. This might be useful if you want to delete any changes made to the firmware or configuration * Print last reset reason of ESP32 * ===== * * Use either of the methods print_reset_reason * or verbose_print_reset_reason to display the * cause for the last reset of this device. I found a reference in tools/sdk/include/esp32/rom/rtc. WiFive Posts: ESP8266EX and ESP32 are some of Using v4. what is the intended reason and cause for RTCWDT_RTC_RESET on boot?
