Hello to all colleagues! ESP32-LyraT V4.3 board. Example PLAY_MP3. The possibility of connecting the ssd1306 monitor to the i2c bus on the LyraT V4.3 board is being studied. At the beginning of the playback of a fragment of mp3, the text "S O U N D S T A R T" should be displayed on the monitor. After playing mp3, the text “F I N I S H S O U N D” should be displayed on the monitor. SSD1306 is attached to I2C Header / JP5. The i2c driver and ssd12306 display are initializing. at the beginning of app_main after which the display shows the text - "S O U N D S T A R T".

Similar errors appear when connecting sd1306 to LyraT V4.3 board and executing VOIP, PLAY_MP3, wifi_bt_ble_coex examples. If you specify the I2C_NUM_1 parameter when installing the i2c driver, then the specified error does not appear. In my opinion, this is not a solution to the problem. In the VOPI example, when the monitor ssd13406 is connected to the i2c bus, an error appears: C:/Users/RN6LJK/esp-idf/components/freertos/queue.c:1443 (xQueueGenericReceive)- assert failed! abort() was called at PC 0x40089925 on core 0
