TWR-KV58F220M I2C DOESN'T WORK

I'm using MCUXpresso IDE v10.02_441 for TWR-KV58F220M programming.I connected TWR-KV58F220M to Elevator model(TWR-ELEV) and then I run "driver example" code in this processor.I followed "driver examples" --> "IC2" --> "interrupt_transfer" --> "read.me" instructions.
Firstly I connected A-71 to A-7 and A-72 to A-8 on A side expension port from TWR-ELEV.I didnt change anything from the example code but I debuged the code and I realized this code can't enter "i2c_slave_callback" function and stuck into "while(!g_SlaveCometionFlag){}" loop and output
"I2C example -- MasterInterrupt_SlaveInterrupt.
Master will send data :
0x 0 0x 1 0x 2 0x 3 0x 4 0x 5 0x 6 0x 7
0x 8 0x 9 0x a 0x b 0x c 0x d 0x e 0x f
0x10 0x11 0x12 0x13 0x14 0x15 0x16 0x17
0x18 0x19 0x1a 0x1b 0x1c 0x1d 0x1e 0x1f"
and stop.
Can anyone help me about this topic?

And I checked I2C0_SCL(83),I2C0_SDA(84),I2C1_SCL(137),I2C1_SCL(138) pins with oscilloscope and there are no change in signals.

Hi BERK,

After connect the I2C signals on TWR-EVEL according to the readme file.

I can see the whole information from the terminal.

I import the i2c\interrupt_transfer example refer 'How to choose UART output during the project import' MCUXpresso IDE and Semihosting.

The on-board debugger use the CMSIS-DAP (Default Image) in TWR-KV58F220M-QSP.

Best Regards,

Robin
