TMDX570LC43HDK: I2C demo communication problem

Hy,

I use two TMDX570LC43HDK board and I want to test I2C communication,

I followed example_i2cSlave_TX_RX but is not provided an Halcogen description, so my description was to enable I2C1 as slave and to pinmux I2C1 pins in a way to use the pin 71 and 72 of J11,

so

pin71 of TMDX570LC43HDK_board_1 is connected to  pin71 of TMDX570LC43HDK_board_2

and

pin72 of TMDX570LC43HDK_board_1 is connected to  pin72 of TMDX570LC43HDK_board_2

the same for the master created on

example_i2cMaster_TX_RX as before is not provided an Halcogen description, so my description was to enable I2C1 as master and to pinmux I2C1 pins in a way to use the pin 71 and 72 of J11,

running the example tx is blocked triing to send and RX is blocked triing to receive.

what could be the problem?

Thanks

Antonio
