Rebootloop when using esp_now on the ESP32 #12258
Description
Description
When using the esp_now network module on the ESP32, the processor keeps rebooting and the system is unusable.
This does not happen when using the esp_now module on an esp8266.
Steps to reproduce the issue
- Checkout the RIOT tutorial according to the instructions
- Install riot/riotbuild in docker according to:
http://doc.riot-os.org/group__cpu__esp32.html#esp32_manual_toolchain_installation - Go to task-05
- Add USEMODULE+=esp_now
- connect esp32 board.
- Try to make and flash and connect to the example using:
make BOARD=ESP32-WROOM-32 PORT=/dev/cu.usbmodem1410 BUILD_IN_DOCKER=1 WERROR=0 ESPTOOL=esptool.py flash term
Expected results
You can connect to the esp32 and use the shell.
Actual results
The shell does not respond and the ESP32 keeps rebooting.
This reboot gives the following information:
