1 month ago Hi @chen-laodi
I was able to reproduce the issue and it went away after increasing stack size of the main task. It seems that if exceptions are disabled, the reported fatal error isn't very readable. After enabling exceptions it just reported stack overflow.

1 month ago @david-cermak Yes, after turning the main task stack size up it seems to be working fine.Thank you CONFIG_ESP_MAIN_TASK_STACK_SIZE=8192

2 weeks ago Hi @david-cermak I encountered another stack overflow issue occurring at esp_modem_new_dev. From examining the source code, I discovered that the exception occurs at this point.
Adjusting the dte_config.task_stack_size to 8192 did not resolve the issue, despite having plenty of PSRAM space.
If you need the complete code, please provide me with your email, and I will send it to you.

auto term = std::make_unique<UartTerminal>(config); // this code stack overflow

The issue is happening in esp_timer task, not the main task, nor the DTE task.

2 weeks ago Hi @david-cermak
I am indeed using esp_timer, but the exception is not generated by esp_timer itself. I created a timer synchronously during the initialization of PHY. If it detects that the Ethernet cable has not been inserted within 10 seconds, it then shuts down the PHY and starts the MODEM.
Due to the insufficient detail in the output logs, I am unable to fully pinpoint the problem. However, I am quite certain that the stack overflow occurs when executing this line: dce = esp_modem_new_dev(ESP_MODEM_DCE_SIM7600, &dte_config, &dce_config, ppp_netif);

General issue report
Problem Description
When using idf4.4.7 ppp to access the Internet, there is an incompatibility problem when starting wifi smart_config at the same time. When switching to idf5.2.1, it can run normally. Is it probably caused by freeRTOS?
After transplanting the pppos_client routine to my project, mqtt sending data and voip receiving calls will also cause this exception. The cost of migrating my project based on idf4.4.7 to idf5.x is very high.
In the attached test code I roughly identified the code that caused the problem
uxBits = xEventGroupWaitBits(s_wifi_event_group, CONNECTED_BIT | ESPTOUCH_DONE_BIT, true, false, portMAX_DELAY);, but I did not have the ability to solve itDebug Logs
