Hi TI pals
I want to fine tune TAS5756M on the board directly, and connect the purepath mother board(J3) to the target board's I2C bus.
select the target as below:
the PPC2 show some warning information as below :
the connection between the purepath mother board to the target customers board is successfully or not?
the configuration profiles is correct or not?
pls give us some suggestion,
many thanks .

hi andy
more question ,please help
this is my conditions，PPC2 mother board 's I2C bus connect to the target board by wire directly.
do you have some guidelines for this use case ?
I follow the material you provided , some different there;
1st, how to get the turning file (.xml), generate it by ourselves? if not, can you give us a sample?
2nd, in Step 1.3. the icon is not like this, it's a warning icon. and I can't stop the hybrid flow.
the below pic is capture by my side:
Hi Andy
we try to use our main board to control the target TAS5756 board by i2c directly, and we try to read the I2C address 0x99~0x9f, there is no ACK signal.
in our design, we pull down the PIN20(ADR1) & PIN26(ADR0) to GND, the i2c address of TAS5756m is 0x98/0x99.
we think the i2c communication is fail , right?
can you give us some suggestion , our schematic and layout design is following the TI's application, is there some key point need to comfirm firstly?
by the way, if we give the i2s signal to the TAS5756m board, the amplifier is work now. we think the TAS5756m is working , but we don't know why the i2c communication is fail.
many thanks for your support.
