Chapter 2. Development environment
2.2.5 How to troubleshoot in ESP32 Boot mode？
• The ESP32-WROVER uses 1.8 V 󰝙ash and PSRAM, which is 0x33 by default in boot status and
0x23 in download mode.
• Other modules use 3.3 V 󰝙ash and PSRAM, which are 0x13 by default in boot status and 0x03
in download mode.
• For detailed information, please refer to Section Strapping Pins in ESP32 Series Datasheet. Taking
0x13 as an example, the pins are as follows:
Pins GPIO12 GPIO0 GPIO2 GPIO4 GPIO15 GPIO5
Level 0 1 0 0 1 1
You can also refer to the Boot Mode Selection documentation directly.
2.2.6 When debugging with ESP32 JLINK, an ERROR occurs as: No Symbols For
Freertos. How can I resolve such issue?
This issue will not a󰝗ect actual operations. For solutions, please go to the ST Community.
2.2.7 How to monitor the free space of the task stack?
The function vTaskList() can be used to print the available space of the task stack regularly. For
detailed information, please refer to CSDN Blog.
2.2.8 Is it possible to use JTAG to debug with ESP32-S2？
Yes. For detailed information, please refer to ESP32-S2 JTAG Debugging.
2.2.9 How to modify the log output without changing the output level of menucong？
To modify the log output without changing the output level of menucon󰝘g, you can use the
esp_log_level_set() function. This function allows you to set the log level for a speci󰝘c module
or subsystem, rather than changing the global log level.
For example, to set the log level for the network module to ESP_LOG_DEBUG, you can use the following
code:
esp_log_level_set("network", ESP_LOG_DEBUG);
For more information about this functinality, please refer to Logging library.
