Rainmaker OTA problem (MEGH-4280) #234

Open Assis08 opened 1 year ago

Assis08 commented 1 year ago

Hello everyone.

I'm using the following rainmaker example with ESP32-S3-WROOM-1-N16 and Arduino IDE:

https://github.com/espressif/arduino-esp32/blob/master/libraries/RainMaker/examples/RMakerSwitch/RMakerSwitch.ino

together with the u8g2 library:

https://github.com/olikraus/u8g2

after finishing rainmaker provisioning, the following error is occurring:

Guru Meditation Error: Core 0 panic'ed (Unhandled debug exception). Debug exception reason: Stack canary watchpoint triggered (Tmr Svc) Core 0 register dump: PC : 0x40380bb3 PS : 0x00060136 A0 : 0x80380d77 A1 : 0x3fcf6080

when I disable the option: RMaker.enableOTA(OTA_USING_TOPICS); the error no longer happens. Can anyone tell me if this could be a rainmaker bug with OTA?

Hi @Assis08 Does the same error occur on the standalone RMakerSwitch example (without adding the u8g2 library) ?

Hi @sanketwadekar

Yes, the problem occurs without the u8g2 library.

@Assis08 Thanks for reporting this issue. The error seen is due to less stack memory allocated to "Tmr Svc" task. This can be configured using CONFIG_FREERTOS_TIMER_TASK_STACK_DEPTH. Increasing it's value will solve this issue. We will fix this in the next release of Arduino (2.0.7).
