ESP8266_RTOS_SDK I2C example causing abort()

Hi, the i2c example code from ESP8266_RTOS_SDK\examples\peripherals\i2c is causing abort().
The example code has not been modified and I have already successfully tested other examples.
I don't have MPU6050 connected !

I made the git clone again from the repository and run the commands:
Code: Select allmake menuconfig
make -j4 flash monitor

Logs:

Code: Select allLeaving...
Hard resetting via RTS pin...

I am using NodeMCU ESP8266 LoLin V3, I have already tested it with other cards and the result is the same.

Does anyone succeed in running this example from the current version ?

Solved. The abort() occurs because I don't have the MCU6050 connected.

The function i2c_example_master_mpu6050_write is called with macro ESP_ERROR_CHECK

ESP_ERROR_CHECK(i2c_example_master_mpu6050_write(i2c_num, PWR_MGMT_1, &cmd_data, 1));

This macro calls abort() function if the return value esp_err_t isn't ESP_OK.
I replaced ESP_ERROR_CHECK for ESP_ERROR_CHECK_WITHOUT_ABORT and the abort() didn't happen anymore.
