After some investigations, I managed to workaround the problem. First, I found that the monitor stops working within the function self.process_panic_output(self._panic_buffer) (idf_monitor.py), so I just commented it as I do not need gdb_panic_server to start. #self.process_panic_output(self._panic_...

Earlier I used esp32 and I often used idf.py monitor to define the cause of crashes. However, with esp32c3 it seems impossible as the Monitor crashed itself upon register dump printing. For example, when my esp32c3 crashes it prints the following to serial port: abort() was called at PC 0x42125df9 o...

Thank you, boarchuz, your answer really help me. Currently, I can access both I2C chips correctly!
Now, I am wondering why Espressif didn't consider disconnecting the previously used Gpios upon the new pair of gpio assigning?

I am trying to communicate with two devices having the same I2C address, so I connected them to different gpio pairs (18,19 and 22,23). In my code, I start the driver (i2c_driver_install), configure it (i2c_param_config) with the first pair of gpios and write 5 bytes to the bus (to the first chip). ...

@PeterR, do you mean it may be necessary to increase tasks stack size if stack overflows? By dumping tasks heaps I get Task name Time spent StackHighWaterMark main 3239354 6364 IDLE0 631724392 1012 Net 49639 2740 tiT 1172789 3304 Tmr Svc 98 1584 BTC_TASK 23726 2872 sys_evt 7911 2816 wifi 50635043 11...

First I faced the problem in my custom firmware and later I reproduced it in a simple example code. In the code below I just merge two examples: examples\bluetooth\bluedroid\ble\ble_spp_server\ and examples\wifi\getting_started\station\ into one file. The resulted code is as following: /* This examp...

Thank you, it really helped to solve the issue!

I'd like to override the original bootloader to extend its functions. Guided by the description from https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/bootloader.html I copied the folder /esp-idf/components/bootloader to /my_project/components/bootloader. The page said one shoul...

@esp_angus, thank you for the explanation. Can you fill us in on the big picture of what this critical section is protecting? I use the critical section as an alternative for mutex in order to decrease overhead. In the case described I use it inside a function that read ADC value which additionally ...

Thank you, ets_printf() is the function I usually use to avoid problems within a critical section but is not convenient each time to predict whether the current procedure will or not be used within a critical section. I was hoping some more convenient practice exists. Nevertheless, is it possible to...
