TDA4VEN-Q1: Does Entry's MCU20 support I2C communication?

Part Number: TDA4VEN-Q1

Tool/software:

Hi experts

I used tda4ventry https://www.ti.com/product/TDA4VEN-Q1 .

SDK 10.0

In muc20 vision app,  opening i2c will result an open failure.

gI2cHandle = I2C_open(i2cInst, &i2cParams);

mcu 20log:

I2C Instance = 1
 VX_ZONE_ERROR:[tivxMutexLock:102] Mutex is NULL
 I2C: ERROR: I2C Open Failed!!!
 VX_ZONE_ERROR:[tivxMutexUnlock:128] Mutex is NULL


After adding appI2cInit() in app_init. c(vision_apps/platform/j722s/rtos/common/app_init.c)

	#ifdef ENABLE_I2C
	appI2cInit();
	#endif

It won't open fail,  But there is no waveform for i2c reading and writing.

Does Entry's MCU20 support I2C communication? 
Have ever encountered this situation ?
