Normal reset after timed wakeup with firebeetle DFR1075
Wolfgang.Koch 2024-11-25 04:24:31 711 Views1 Replies Hallo,
I am using the following code to get the Firebeetle (ESP32-C6) into deep sleep and wake up after some time. Code ist compiled in Arduino IDE.
esp_sleep_enable_timer_wakeup(2000000);
esp_deep_sleep_start();
I need to store an integer value in RTC-memory to be available after restart. It is defined with RTC_DATA_ATTR attribute.
But this does not work. The ESP32 wakes up, but the variable contains 0, and the wakup-reason is not the timer but a normal hardware reset. I use esp_sleep_get_wakeup_cause() for retrieving the wakeup-reason.
It is not a problem of power supply, I have tested it with different supplies which deliver enough power.
The code works for me with an older ESP32.
Thanks in advance for any ideas!
I have the same problem with deep sleep wakeup. But what i see is that there is a ROM logging at serial monitor like this:
09:59:51.982 -> ESP-ROM:esp32c6-20220919
09:59:51.982 -> Build:Sep 19 2022
09:59:51.982 -> rst:0x3 (LP_SW_HPSYS),boot:0x2b (SPI_FAST_FLASH_BOOT)
09:59:51.982 -> Saved PC:0x4001974a
09:59:51.982 -> SPIWP:0xee
09:59:52.026 -> mode:DIO, clock div:2
09:59:52.026 -> load:0x4086c410,len:0xcf8
09:59:52.026 -> load:0x4086e610,len:0x2e30
09:59:52.026 -> load:0x40875728,len:0x113c
09:59:52.026 -> entry 0x4086c410
Than the ESP performs a reset. This happens at different times and only sometimes it works fine.
May be it helps to find a solution.
Thanks.
