I try the example available on m5stack GitHub (https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Application/Bala2) without success. I build project from Arduino IDE and from plaformIO with the same issue. After download binary file on bala2, screen remains black and motors are turned off. I can just do gyroscope calibration when btnB is pressed at power on. With verbose log enable, there is following error: "getBytesLength(): nvs_get_blob len fail: angle NOT_FOUND "

Please let me known how I can solve problem, all framework and libraries seem to be updated.
